Solid stuff from Dodgers' de la Rosa 

March, 31, 2009
Notes from my last day in spring training, at the Dodgers/Brewers A-ball games:

The best stuff of the day belonged to Rubby de la Rosa of the Dodgers, who turned 20 earlier this month and has yet to pitch in a pro game in the United States. De la Rosa sat at 91-95 mph with a solid changeup from 84-86 that he turns over hard. His breaking ball was a slow curve in the mid-70s, although the harder he threw it the sharper the break became. He clearly has the arm speed to throw a good breaking ball and the laxity in his wrist to throw a curve, so it might just be a matter of development with better coaches as he moves up. The two red flags on de la Rosa were poor command Monday and the fact that his listed weight of 170 might be generous.

Pedro Lambertus was the best Brewer arm for velocity, touching 95 a handful of times and pitching well for a few batters until the wheels came off after the center fielder dropped a routine fly for the third out. He sat at 91-95, just like de la Rosa, but his secondary stuff wasn't as strong, with a hard changeup at 86-87 and a flat slider in the low 80s. He has good arm speed on the changeup, but it's probably too close in velocity to the lower end of his fastball range. Lambertus has more walks than strikeouts in his pro career, so his stuff is interesting, but it doesn't seem to play just yet.
