I could do this for hitters, too, but hitters are boring.
This is (probably) not a complete list, so please fill me in if I'm missing something.
- Ryan Rowland-Smith is working on a cutter
- Shawn Kelley is bringing back his changeup
Kanekoa Texeira apparently throws a cutter (don't know if this counts)
- Luke French is trying hard to improve his change, and throw it more
- Jered Weaver is experimenting with a cutter/slider hybrid, recommended by Joel Pineiro
- Jered Weaver is also working on improving his two-seam fastball, which he had but didn't use a whole lot in 2009
- Brian Fuentes hasn't recovered his lost velocity yet
- Ervin Santana hasn't either
- Scott Kazmir is throwing his slider with a new grip, using his middle finger instead of his index. Based on the description is sounds like it's similar to Weaver's new slider
- Neftali Feliz appears to be headed back to the bullpen
- Derek Holland appears to be headed back to AAA
- Matt Harrison claims to have improved velocity after surgery to relieve thoracic outlet syndrome, but a few days ago he averaged 91.3mph over a four-inning appearance, matching up with last year's 91.1
- In case you were wondering about round-trip traveler Colby Lewis, he's got a low-90s fastball, a cutter, a curve, a slider, and a change. Don't know anything about quality
- Brandon McCarthy has played with a cutter this spring, and from the sounds of things, so have a lot of his teammates
- McCarthy has also revamped his mechanics to, I believe, reduce the stress on his shoulder
- Gio Gonzalez has adjusted his changeup grip
- It seems Brett Anderson wants to use his changeup more
- Don't know if this means anything, but Ben Sheets says he made a little arm angle adjustment after that one ten run/no out start of his
- Trevor Cahill has a new curve that he'd like to use as a strikeout pitch
In injury news, rotation favorite Tommy Hunter strained his oblique, and like the entire A's bullpen is hurt.
