Prospect Retrospective: Mike Napoli
Mike Napoli Prospect Retro
The big hero for the Texas Rangers in Game Five of the World Series was catcher Mike Napoli, who is the topic of today's Prospect Retrospective.
Mike Napoli was drafted by the Anaheim Angels in the 17th round in 2000, from high school in Cooper City, Florida (population 27,939 in the 2000 census, median family income $78,172, part of the South Florida Metro). He was assigned to Butte in the Pioneer League after signing, but was limited to just 10 games by a back injury, hitting .231/.400/.308 in those contests. He got off to a late start again in 2001 and played 50 games in A-ball, 43 for Low-A Cedar Rapids (.232/.341/.406) and seven for High-A Rancho Cucamonga (.200/.429/.350). He wasn't really on the radar as a prospect at this point, except among the most fanatic Angels fans.
Napoli got a full season with Cedar Rapids in 2002, hitting .251/.362/.392 with 10 homers and 62 walks in 362 at-bats. This was when I first became aware of him, seeing him play a couple of games in the Midwest League. He looked like a guy with some pop in his bat and a willingness to work counts, but he was quite slow and I wasn't impressed with his movements behind the plate. I didn't put him in the 2003 book but would have given him a Grade C if I had.
Promoted back to Rancho Cucamonga for 2003, Napoli missed all but 47 games with a labrum injury, hitting .267/.362/.412 in those 165 at-bats. He drew some attention for his patience and power potential, but scouts remained skeptical about his glove and wondered how the injury would impact his future.
2004 was a big step forward: he stayed healthy, played 132 games for Rancho, hitting .282/.393/.539 with 29 homers, 118 RBI, and 88 walks in 482 at-bats. He also struck out 166 times and split the season between catcher and first base, and impressed no one with his glove at either position. He was also diagnosed with arthritis in his shoulder, not what you want to see from a 23-year-old. Scouts complained that his swing was too long. I gave him a Grade C+ in the 2005 book, writing that "I think his power will carry forward to higher levels, but he's probably a .240 hitter against better pitching. If he continues to draw walks, that will be enough."
Moved up to Double-A Arkansas in 2005, he hit .237/.372/.508 with 31 homers, 88 walks, and 140 strikeouts in 439 at-bats, performing as anticipated, losing batting average but maintaining the power and patience. He also threw out 47% of runners trying to steal on him. Scouts continued to complain about his lack of mobility, but admitted that his throwing had improved and began praising his leadership skills. I rated him a Grade C+ in the '06 book, writing that he would fit well as a catcher/first base/DH type and that he would be "something like a cross between Matt LeCroy, Mickey Tettleton, and Rob Deer."
Napoli spent most of 2006 in the majors, hitting .228/.360/.455 for the Angels, and has been in the majors ever since with Los Angeles and, this year, the Texas Rangers after having been shipped to Toronto for Vernon Wells and then from Canada to Texas for Frank Francisco. He has been a consistent power source, hitting 122 homers in 619 games, with a career line of .264/.359/.514 and averaging 32 homers and 68 walks per 162 games. His career OPS+ is 129 and he's never had a season where his OPS+ was below league average. His WARs have been solid: 2.6 in '06, 1.5 in '07, 2.8 in '08, 3.0 in '09, 2.7 in '10, and an outstanding 5.6 in '11, giving him a 18.2 in his career through age 29.
As you know, his 2011 season was tremendous: .320/.414/.631 with 30 homers, 171 OPS+, and now post-season heroics. He's not a terrific defensive catcher but he's not horrible, and his bat covers for any deficiencies.
Although Mickey Tettleton never hit .320, his power/patience approach and ability to play catcher and first base without killing you still reminds me of Napoli. Tettleton finished with a career 31.8 WAR, with his peak seasons being 1989 at age 29 (.258/.369/.509, 150 OPS+, 4.8 WAR) and 1991 at age 30 (.263/.387/.491, 140 OPS+, 6.0 WAR). I think Napoli can follow a similar path, with 2011 being his peak season paralleling Tettleton, with a slow decline in his early 30s.
You may recall that when Napoli was a prospect, his main competition in the Angels system was Jeff Mathis, a much superior athlete with more respect from scouts for his tools. Mathis is a career .194/.257/.301 hitter; Napoli outclasses him by a huge amount offensively.
But what about their gloves? How does their defense compare?
Mathis has played 3307 innings behind home plate. In those innings, he has given up 27 passed balls, committed 37 errors, while collecting 252 assists. He has thrown out 24% of runners in his career.
Napoli has played 3729 innings behind home plate. In those innings, he has given up 21 passed balls, made 34 errors, while collecting 206 assists and throwing out 25% of runners.
Per inning, Napoli actually makes fewer errors and gives up fewer passed balls than Mathis, while throwing out runners at a comparable rate. However, Mathis has a big lead with assists, reflecting his greater quickness and mobility, and the more sophisticated sabermetric defensive measures are impressed with him. Fielding Bible rates Napoli quite poorly at -18 Defensive Runs Saved as a catcher over his career, while Mathis comes out positive at +10 DRS.
Ultimately, however, Napoli's greatly superior bat eliminates any value advantage Mathis gains for being better with the glove. In this case, superior skills trumped superior tools.

good write up
Thanks, John. What a year and post season he’s had.

Napoli vs Mathis Defensive Comp
I was surprised to see how similar their stats were (aside from Assists) it sounds like Napoli was extremely undervalued by the Angels and for that matter the Blue Jays (albeit to a lesser degree). That Napoli trade was a classic example of a GM being reactive to the market and letting a mild failure turn into a big one.
Reagins missed on Crawford and tried to make a splash with Wells and it just blew up. Its bad enough they have Wells and his contract, but losing Napoli’s 20+ HR’s a year and leaving Abreu to DH too often is almost worse. Hopefully Hank Conger make up for the loss of Napoli.
Out of curiosity what do you think the chances of Napoli maintaining a BA above .260 next year?

napoli in toronto
I think part of the problem with retaining napoli in toronto is jp arencibia. Front office wanted him to play and there was already too many outfielder/dh/1b types on the club but a need for relief/closer…which is what frankie francisco is.

how much is that
Just that Angels don’t value hitters who can’t seem to hit for average - something I remember carrying over from the earlier part of the decade and Scioscia’s style? His other numbers looked great, but the BA was always bad.

superb Baseball Prospectus piece on Scioscia, Napoli, and Mathis
Bottom line, perhaps: If there’s one manager you’d expect to value a catcher’s perceived defensive reputation (and particularly his impact on the pitching staff), it’s Mike Scioscia.

How would you compare Napoli's game to Derek Norris?
Norris has the patience and pop and the last two seasons the lower batting average to go with them. He’s raking in the AFL, but while hopeful that’s obviously SSS at this point.

i think they are similar in a lot of ways, and Norris has better raw tools

you also...
… said in a Ryan Lavarnway write up a while back that a comparison for his was Napoli. With the season that Napoli had this year, and the way that he’s played in the playoffs, is that high praise for what Lavarnway could be?
by noelman31 on Oct 25, 2025 9:40 PM EDT up reply actions
that said
Napoli is playing at somewhere between his 95th and 5,972nd percentile right now. I suppose it gives some optimism for Norris’ future, but if he wants to be anything like this, I hope his dial goes to 12 (yes, I said 12).

Very true.
With that minor league line, all signs pointed to him King his way out of the league quickly. The odds of him turning into the player he is now were slim to none, and that might even be generous.

I think this is the epitome of Mike Sciosia's stubborness as a manager...
and is why many Angels fans wonder if he deserves to remain as the Angels manager. This is heart wrenching as an Angels fan.

brutal
No matter how much better Mathis is behind the plate, those offensive numbers are just no match.
Napoli sometimes reminds me of a lesser Adam Dunn - not as much power or patience, but slightly better average and less strikeouts
by nickramz on Oct 25, 2025 8:54 PM EDT up reply actions
let's be fair
“Slightly” better average has gone out the window. He’s cut the strikeouts substantially and his average has shot up as a result. You can’t even attribute his improvement to the move to the Texas environment - somehow managed to be even better on the road this year!
The only limitation on Napoli’s season is that he had less than 450 plate appearances (making his season numbers even more absurd). On the whole, though, we have just witnessed one of the greatest single offensive campaigns by a catcher.

Naps has been great.
Sotra wish T.O would have kept him Escobar,thames, bautista, lind, napoli, lawrie, rasmus, arencibia, there alot of good hitters in rhere.

Is there even a close second argument for worst trade for all time?
The other bad trades of all time at least involved prospects, clubhouse cancers or salary dumps. I don’t remember any other trade being universally thought as terrible at the time of trade by every pundit, front office (cept the Angels) and baseball nerd.

Exhibit A as to why Scioscia is a seriously flawed manager
The Angels really blew this one although, to be fair, no one knew that Napoli could be this good (and he likely never will be again). One of the reasons that the Angels got rid of Napoli is because they thought they had a similar, younger, and potentially better catcher in Hank Conger. Let’s give Conger more than 72 games to prove that he can’t be all that Napoli was (as an Angel) and more.
While I absolutely hated that trade then and now and think Mathis should be a back-up at best, to play Devil’s Advocate for a moment on the Mathis vs. Napoli thing, one thing defensive metrics don’t show is how good a catcher is at gaming calling and working with pitchers in general. I’ve heard various anecdotes that Mathis is masterful and Napoli sub-par. Take that for what you will.

One more thing about Scioscia
I wrote “seriously flawed” but that doesn’t mean I don’t think he isn’t a good manager. It is hard to argue with the results: Scioscia has managed to win a lot of divisional races with good-to-very-good-but-not-great teams; his teams consistently outperform their Pythagorean Records and he manages to find ways to win ball games in little ways. We shouldn’t let the Napoli Scandal or the fact that Tony Reagins made some terrible moves obscure the fact that not only is he the most successful manager in franchise history, but he’s one of the most successful managers over the last decade.
by Angelsjunky7 on Oct 26, 2025 11:45 AM EDT reply actions
on the flip side
how good were the teams that Scioscia had to compete against, when he won those divisional races? how much of his winning was noise, and how much was true skill?

I think Napoli
given his treatment/usage with the Angels, his modest prospect background, his offensive explosion this season (and that drop in his k-rate), and his postseason heroics, is making a strong case for a new metric ‘Mancrushes Above Replacement’
