Oakland's trade of Dan Haren once looked like a bid for quantity over quality, but the rapid progression of left-hander Brett Anderson has changed that.
Anderson, the 20th-best prospect in baseball and the third-best left-handed prospect, showed great command of a four-pitch mix on Sunday along with excellent feel for pitching. Anderson was 91-93 mph with good life on the pitch, and he mixed in a sharp two-plane curve from 76-81 mph, an above-average changeup with great arm speed from 82-84 mph and a short cutter/slider in the same range as the changeup. He threw everything for strikes and showed uncanny feel for a pitcher his age, setting up hitters, changing speeds, and changing eye levels.
He's a quick worker with an aggressive approach and a clean delivery that he repeats well. Anderson only has six starts above A-ball, but he's never been challenged in pro ball, and both his stuff and polish are big league-ready.
