Prospect Video: Luis Martinez, Corey Kluber

San Diego Padres prospects Luis Martinez and Corey Kluber took steps forward in 2009. Martinez showed more in the stick than in previous seasons to go along with terrific defense. Kluber gained confidence through the year, ending up in Double-A.

Luis Martinez, known for his defense, shows off his impressive arm in one clip, taking a ball on the outer half of the plate and making a quick transition to his throwing arm to throw a runner out. He has also simplified his hitting approach to get the bat head through the zone quicker.

Corey Kluber suffered from a lack of confidence in 2008 but bounced back this past year to show why the Padres are confident in his abilities. A smooth delivery is part of his draw - the movement on his two-seamer is evident and an emerging changeup is visible.
