Looking at Bumgarner's season
Probably the most debated prospect of the year. Season looks to be finished (besides maybe a playoff start). Ended the season with some pretty good stats for a 20/21 year old.
18 GS
111 IP
3.00 ERA
3.72 FIP
86 K (6.97 K/9)
26 BB (2.11 B/9)
3.31 K/BB
Ended the season on fire. In 5 September starts, Bumgarner has a 1.12 ERA in 32 innings while striking out 32 and walking only 4 and giving up only 1 HR.
It also looks like Bumgarner's veloctiy is back. In his September starts:
9/23 - Avg 4 seam velocity 91.5, Max 93.2... Avg 2 seam velocity 91.6, Max 93.2
9/17 - Avg 4 seam velocity 91.9, Max 94.3... Avg 2 seam veloctiy 92, Max 93.9
9/11 - Avg 4 seam velocity 92.7, Max 93.9... Avg 2 seam velocity 92.9, Max 94.9
9/6 - Avg 4 seam velocity 91.9, Max 93.9... Avg 2 seam velocity 92.6, Max 94.3
His average veloctiy has been around 92 MPH. Other lefties this season
Price 95.3
Kershaw 92.5
Lester 93.5
Santana 89.6
Anderson 92.9
Jamie Garcia 90
Hamels 91.7
CC 93.6
Sanchez 90.6
Pettitte 89
Lee 91.1
What are your thoughts on Bumgarner now after a really successful 20/21 year old season and his regained velocity?

Mad Bum is an ace in the making
It’s not even fair that the Giants have Tim, Matty, and Dirty Sanchez to go along with him.
"The BB's are out. The BB's are being arseholes to me." - Brian Wilson.
he'd rate very highly were he still prospect-eligible
He’s come a long way this year, flashing some very respectable secondaries and working the plate nicely. Great example of a guy who’s bought himself some breathing room to develop thanks to strong fastball command. You can project a lot of things, but it’s really hard to project a guy learning how to throw his fastball in such a way to consistently preserve that magic combination of velocity, movement, and command. Bumgarner has that down, and he’s making excellent use of that breathing room I mentioned to develop his game.
This all being said, he’s not necessarily a frontline starter in the making. He could certainly go that way, but we’ll need to see how well he’s able to keep bats off of his pitches once the element of surprise has fully dissipated. If he can up those strikeouts just a bit more while maintaining the rest of peripherals, then yeah, we’ve really got something here. Even if he doesn’t make that extra jump, he should stick for a while good health permitting as a very respectable No. 3 type that plays up in SF.
+1
Agree with all of this- I think he’s more likely to be a good mid-rotation guy. But even that’s still a great asset for the Giants, and obviously there’s room for him to be more than that.

Hmmph.
Won’t change anything since most Giants fans consider Cain an “Ace” too.

Mr Sabean is Genius
Giants GM jumped down the throat of Madison Bumgarner early in the season and Bummy turned his season around. Giants GM jumped down the throat of SF Giants starters and the pitching staff turned it back around in September.
Bumgarner is an Ace in waiting.
I agree with all of what you wrote, except for the “Sabean is a genius” part. It was a well-desiminated story that pitching guru Dick Tidrow spent some time with MadBum in Fresno back in April (after his disastrous first start in AAA) and found a flaw in his mechanics that was responsible for his lost velocity. They worked on it and his velocity has slowly been increasing all season long. Tidrow is the genius.

That really worked with Ned doing that to Kemp this year, eh?
"If we hit that bull's eye, the rest of the dominoes will fall like a house of cards. Checkmate"
why is he an ace in the making?
because he has had success as a young pitcher? he looks like a good pitcher. ace is a stretch, a lot would have to go right because the stuff isnt great but good. command is plus.
Because his FB velocity has come back from the 89-91 mph range to the 92-94 mph range. You just don’t see that velocity in a LH starting pitcher that has his kind of control and command, not to mention that he has 3 other pitches he can consistently throw for strikes – including a changeup that is fast becoming a plus pitch.
As mentioned, his velocity finally started coming back at the end of August (the OP has it wrong when he writes about his “5 August starts” – it should read “5 Sept. starts”). Since then he’s averaged over 9 K/inning (he had 7 more Ks today in 5 IPs), while giving up only 1.2 BB/inning. That’s a K/BB of 7.8.
"There ain’t much to being a ballplayer, if you’re a ballplayer." - Honus Wagner
Look at Jon Lester for example
I think of Bumgarner as a similar pitcher.. Lester had a 6.6 K/9 as a 22 year old rookie. He had a 6.5 K rate as little as two years ago. Lester allowed 10.1 H/9 as a rookie…
I think Lester has better secondary stuff, not to say that Bumgarner can’t get there. That said, the division/league/home park differences could make Bumgarner look as good, if not better than Lester.

Great piece about his stuff on FG:http://www.fangraphs.com/blogs/index.php/analyzing-madison-bumgarners-pitches/
I don’t think he is close to an ace, FWIW. He’ll need to get his K Rate way up to get into ace territory. Right now, he is a very good young pitcher though.

K rate need to go way up?
His K/9 is only .5 lower than Sabathia’s. 1 lower than Halladay and Cliff Lee. He doesn’t have to strike out 8+ per 9 to be an ace.
exactly
And since his velocity returned he’s got a K/9 of 9.5. Only 13 starters (with at least 100 IPs) in the majors this year have averaged over 9.0 K/9, all but Bud Norris and Jhoulys Chacin are the aces of their staffs.

RE
First, K/9 is kind of an outdated stat. You’re better off looking at K/PA, and actually using context rather than pulling a few random names out of a hat. The league average is 18.4%. Bumgarner’s is 17.2. I’m not sure how that puts him in the top 15-20 pitchers in baseball.

Random names?
I was just pointing out pitchers that are aces that weren’t that far ahead of him in the K department. Nothing random about it.
Not sure how you have Bum at 17.2%. He has 86 Ks against 472 batters faced. That’s 18.2%. Sabathia, Lee, Halladay are at around 20-22%. I don’t see how that’s “way up” from Bumgarner. That’s one more strikeout for ever 33 batters faced. And you have other guys who could be aces depending on your definition of ace (Santana, Buchholz, Carpenter, Cain) that have even lower rates.

That's not counting todays start
7 more Ks and 24 more batters faced. Up to 18.2 after today. I agree that he does need to improve it slightly, but to say his K rates need to go way up is a bit far IMO.
Fine
But overall, his swinging strike rate is below average, his k rate is below average, and his fly ball tendency isn’t hurting him because of his park. He has been great at limiting walks and and keeping the ball in the park, but he is far from an ace.

Yes, it’s an extremely SSS, but the point I was making is those are the only results that we have where his FB velocity is back at least close to what it was in 2007-2008 (and the first third of 2009). He’s shown throughout his career that he is a way above-average strikeout pitcher when his velocity is that high.
The question is, will he be able to maintain the velocity going forward? IMO the answer is most likely, yes. The fact that he has seen the increased velocity at the very end of the longest season he’s ever had, where he’s pitched way more innings than he ever has, tells me that the loss of velocity was related to mechanics and not a physical limitation. If he can throw that fast when he’s worn out, he should gain even a bit more velocity at the begining of a season when he’s fresh.

Your rationale that follows is sound, but that by no means that his velocity, is mostly to stay. That certainly is the question though.

The Baseball Analysts have done some stuff on it,
K/Pitch >> K/Batter Faced >> K/9
If batter faced is available why not use it? For MLB its available. Certainly the term outdated was an overstatement. I was in a law library from 2 PM until 1AM straight last night after waking up at 5:30am, a little delusional.. lol

How is 91.2 mph "around 92?

Not sure where you get 91.2 from
In September his average velocities each game have been
4 seam – 91.9, 92.7, 91.9, 91.5
2 seam – 92.6, 92.9, 92, 91.6
Ah. It was not clear that was in September.
The other numbers is from fangraphs and his AVG on the season.

everybody keeps hating on bumgarner
only to be proven wrong again and again…
Yeah, that's why the debate keeps surfacing...
I’ve been debating MadBum on this site for over a year now, and the reason the debate is now infamous, is that the detractors are surprisingly persistent in this case vs others. This thread is a great example of how the detractors really want to find something bad about his performance, even when, especially recently, it has been excellent even compared to the league’s best pitchers.
I think it was the last debate where someone said, yeah, he’s good, and he may be good for 3-4 years, but then he’s going to the pen. No real rationale, and at that point, there’s no point to debating it.
We’ll just wait and see, and given the most recent performance and initial returns on his stuff, I don’t know how anyone could honestly argue that he doesn’t have ace potential. He may not sustain it, but especially in the past month, he has posted ace-like stats as a 21 year old. I don’t see any reason for pessimism.

Its because the fight keeps changing
He may not sustain it, but especially in the past month, he has posted ace-like stats as a 21 year old. I don’t see any reason for pessimism.
The argument now is that he ace-like, or will be ace-like next season, or in the near future as opposed to his prospect status before. I’ll admit, he has been slight better than I have expected. But the ace claims are premature.

The argument is the same to me...
Many were arguing for him to be a top 15 prospect on our community list, and defending the top 15 ranking he got from BA, and for me, that is the same as arguing he could develop into a future ace. It’s how I handle rankings vs how someone like PP does. If a player is a top 15-20 prospect, and continues to develop, then they should be expected to be all-stars/ace type players.
So the argument is the same, except as we go, there are fewer and fewer flaws in his game. Last year the debate was far more balanced as he posted 1 WHIPs in AA/AAA as a 20-21 year old, but was doing it with a upper-80s fastball and showed little secondary pitches. But now, he’s in the low 90s, showing more secondary stuff, dominating in the majors at 21, and getting stronger as he goes.
The detractors have less and less of a foothold to push back on the argument that this guy has ace potential and is on track to be an ace, but the push back continues! The line keeps getting moved from “yeah that stuff won’t play in AA, or AAA or the majors, or he’ll get hit in his second time through the league or next month or next year or 3-4 years from now, then he’ll collapse and end up in the pen”. It’s what rose this debate to a ridiculous level.
Like with Stanton, for instance, some thought the Ks would catch up to him in the majors (myself included), but I’ll admit being wrong at that. If he continues to play as he is, which is kinda silly to say given his age, then he could be a Dunn-like producer, which is great. I suspect he’ll improve and could elevate his game. MadBum doesn’t get that same treatment, even though he continues to improve, and produce.
Poster formerly known as artie
It could be semantics, however...
As we may all define Ace as something different. Like is Cliff Lee an ace? Or Tim Hudson? or Glavine with more Ks.
As I said this off-season, I could see MadBum posting peak Tim Hudson numbers, a low WHIP, walking around between 2-3 per 9, striking out around 7 per 9, and logging 200+ innings a year. That, to me, is ace potential type numbers, with a little luck, he could grab a Cy with those numbers.
But given his velocity improvement, and statistical improvement across the board, as the season wore on, I think a reasonable argument could be made that he could improve on those numbers.
Poster formerly known as artie
I know Hudson is a big GB pitcher...
that I understand, I’m not saying MadBum = Hudson, just that given his performance to date, MadBum could produce that kind of surface stat line.
However, that was with diminished velocity, now that his velocity is staying in the low 90s along with that a k rate increase, I think we could expect a low WHIP, 7-8 Ks, 2-3 BBs from MadBum, which profiles as ace potential to me.

The problem was that people discounted them
Everyone was worrying about his declining velocity/k rate, while ignoring the fact that he continued getting results.
by King Billy Royal on Oct 1, 2010 2:19 PM EDT up reply actions
People were correct to discount them
It would be wrong to correlate Bumgarner’s ERA/Wins from the minors to his ERA/Wins this season in the majors. He put up ridiculous ERA/Win numbers last year throwing in the mid/upper 80’s due to absurdly low BABIP and infield fly rates, both of which were not sustainable. He’s putting up good ERA/Win totals in the majors because his stuff has returned and he’s striking more people out — his BABIP and infield fly numbers are normal-to-unlucky.
Worrying about the velocity/K rate was the right thing to do – the fact that they rebounded are the reasons for his current success.
Yeah...
and a decrease in velocity – are people supposed to ignore this? His K rate dropped along with the velocity.
There’s no responsible way to ignore this kind of data point without being a big homer.

I somewhat agree with you...
however, and here’s where the debate frustrates people, as much as the homers wouldn’t admit the impact of his failings, the detractors do the same on his improvements. It’s like no one wants to give any ground either way regardless of the evidence.
Even seeing his best stretch in the majors was his last month with his best, after 13 starts in the bigs (over a third of a season), with increasing, sustained velocity, and you still say wait until the league gets a better look at him. I mean isn’t it time to admit he’s bounced back to be a top 10 prospect and potential ace?
Check out the PP write up from spring 2009, when they said he was the #2 pitching prospect behind Price, and a potential ace and it sounds alot like the pitcher we see now.
I certainly didn’t discount the importance of the velocity drop, but I still saw a young kid, striking out between 6-7 per 9 and maintaining a 1 WHIP. We can debate the BABIP stuff til we’re blue in the face, but there are studies that show better hitters maintain a high BABIP and better pitchers maintain a lower one. It makes total sense because there’s a direct relationship between the two. So who is to say that level of BABIP for MadBum is unsustainable when he sustained that level for his minor league career?
But it doesn’t even matter, he pitched through that stretch, still pitched well even with diminished stuff, and now is progressively increasing his velocity, and getting great results from it and all as a 21 year old. To say he wouldn’t be a worthy top 10 prospect, or a potential ace, just isn’t objectively evaluating his stuff or performance.

His performance i’s making my “crazy” crystal ball of Madison look a little better as well. I always believed in ya kid! And I’m no homer, the Padres are my team.

He's going to be very good.
The stuff isn’t unimpressive, it works well together, he repeats his mechanics, the fastball command has elite potential, he has a good changeup…Plus there’s the offhand chance he gains a tick on his fastball as his body develops…Either way I like him alot in the long run.
