Zack Weiss

Weiss was BA's No. 32 prospect going into the 2010 draft out of high school in Southern California, and the Pirates made him a 10th-round pick. He decided to head to UCLA instead. He never emerged as a dependable weekend starter but found his niche as a reliever this spring, going 2-1, 2.60 through 35 innings. Weiss has a durable build (6-foot-3, 210 pounds) and a four-pitch repertoire, with an 89-92 mph fastball, an average downer curve, a serviceable short slider and feel for a changeup. But his fastball is true and can get squared up, and he has a tendency to leave the ball up in the zone. Scouts also question his toughness when things get tough. His stuff should still get him drafted toward the back of the top 10 rounds.
