His stuff isn't far from what it was, but a lack of consistency and command are preventing him from reaching his potential. Miller struggled to find the strike zone in Triple-A at the start of 2007, resulting in a demotion, and had a 12.79 ERA with 23 hits and 16 walks in 13 innings in the Arizona Fall League following the season.
His arm action is deeper in back that it once was, and though he showed better durability last year, his fastball command was nonexistant at times. He still pitches in the low 90s and touches 95 MPH, and his 83-87 MPH slider grades as a plus-plus pitch at times giving him the weapons to profile at least as a situational reliver if he rediscovers his feel for the strike zone.
He shows much better command of his slider than he does his fastball. He also throws a curveball, cutter, and changeup, but doesn't get to them often because he's too frequently behind in counts.
Miller remains on the Dodgers' 40-man roster, and they're optimistic he'll fill a role in their major league bullpen. That will come as soon as he figures out how to consistently throw strikes.
