2010-03-10 18:00:00 (link to chat)I saw Bumgarner pitch for the now-defunct Connecticut Defenders (AA) in late August, and he was throwing 85-86 on the stadium gun all night, with a half-dozen 87s at most. He attacked hitters and hit spots, but he looked more like a mid-rotation lefty than an electric prospect. The numbers weren't great, either. Thoughts?
(Mike M. from Bridgeport, CT)
I've often felt that scouting reports and what the fans parse out of them is subject to the vicious circle of the confirmation bias. That is -- I tell you John Jaha is a terrible person and when you see him not sign an autograph your mind processes what I said and leads you to the decision that he snubbed the fan because of his awful nature, whereas if I opined he was the greatest great man of all-time, you would look for excuses to explain why he didn't sign the autograph.

In other words, we see what we want to see, in part based on what we've heard. If Scout #1 says Bumgarner is the bees knees, then Scouts #2 and #3 may see him do 1-2 things really well and just agree that Scout #1 knows what he's talking about. I'm not saying this happened specifically with Bumgarner, but rather that with prospects it can be a very slippery slope.

With that out of the way, Kevin Goldstein reported that Bumgarner's dropoff in velocity is believed to be the byproduct of fatigue and a self-imposed schedule that had him throwing far too hard. I wouldn't worry. It's likely his numbers are correlated strongly to the velocity, and assuming that returns so too will his dominance. (Eric Seidman)
2010-03-10 18:00:00 (link to chat)Only baseball sight in the world where I can still get a John Jaha reference. Love it!
(SupercoolTrae from Oakland, CA)
The choices were Jaha, Matt Mieske, or Mitch Meluskey. (Eric Seidman)
