I got to see Bryce Harper play last night for the first time. It is hard to believe he just turned 18. I would rate his raw power at an 80 on the traditional scale. He's got outstanding bat speed, and while he can be fooled at this point, he did make an effort to work the count and showed the ability to make adjustments in the same at-bat. It was just one game but I saw enough to completely buy into the hype.
Brandon Belt is outstanding too. His swing is completely different than what I saw at the University of Texas a couple of years ago. It is shorter now and he no longer gets tied up inside. He's also fast for a big guy, has a long stride, and he plays hard. I'm very impressed.
