We might have to agree on what constitutes firstball hitter, clutch, and table setter (and all abilities like that). We should spend time doing that. When editing the Philthies yesterday, I was going to take firstball hitter away from Ryan Howard because I couldn't find the B-R splits section to back it up. Then I found it - the dude hits .379 on the first pitch. That's like 100 points better than his career BA against righties (and .160 over his lefties line), so I was convinced.
On Clutch and Table Setter -
Trout has a career .305 batting average. That's just over the line to a contact of 11, which you are planning on giving him - seems fine to me. But the clutch/table setter BA is all within 10 points of his career average...and both still within the contact of 11 range (.305-.319). So I would nix both of those - or nerf contact to 9 or something to compensate. I'd leave Trout's contact at 9 until the very end just in case I got too many blues anyway, but that's me allowing for my own messups
For first pitch -
I think, because players will swing at the first pitch in certain beneficial-to-batting-average situations (tiring pitcher, guessing right on the pitch, hit and run, etc) that nearly everyone will have a higher BA on first pitch than their career line. Just randomly poking around, Jason Varitek hits the first pitch over 100 points better, Shane Victorino hits the first pitch 70 points better, Yuniesky Betancourt is 32 points better. Betancourt is a crummy hitter, right?
Remember that the B-R first pitch stats are just on first pitches that were swung on and ended the at-bat. So that means swing-and-miss doesn't even factor in. I would stipulate that we need a certain large spread between career BA and first pitch BA before awarding firstball hitter - whatever we can agree on after looking at enough sample data. I'd say a minimum of .069 points, maybe more like .100 though. A swing of just .036 like Trout's doesn't seem worthy of the ability to me.
And believe me, I think Trout is the best player in the game, so if there were room to teeter I would teeter towards giving him more, not less.
I think Trout should get Contact Hitter, fwiw.
