D-Backs keep top prospects
In exchange, the Yankees received more pitching depth, although nothing resembling the high-end prospect they allegedly were going to receive. The one big leaguer they obtained was Luis Vizcaino, a hard-throwing middle reliever with iffy control but outstanding strikeout rates (except for his one year in the American League) who is probably a seventh-inning guy for the Yanks. His fastball is straight, and he's susceptible to the longball, limiting his upside, especially given the opposition he'll face as a Yankee. He has improved his splitter to where it's an average pitch, making him more than just a right-handed specialist.
Neither Ross Ohlendorf nor Steven Jackson projects as more than a reliever in the big leagues. Ohlendorf has remade himself since he was drafted out of some nondescript liberal arts school (Princeton) in New Jersey in 2004; in college, he had plus velocity but his fastball was straight, and his command was below-average, but he's exchanged a little velocity for some sink on his fastball, he's improved his changeup, and now pounds the strike zone. He has an average-to-plus slider with very good depth that is probably his best pitch to get swings and misses. He's got an outside chance to be a starter in the majors, particularly if he improves either of those secondary pitches.
