View Draft Report
Harrold, a 6-foot-1 junior who closed and has a higher ceiling, improved his command working out of the bullpen and flashed some 94s on radar guns, sitting at 91-92 mph. His slider has improved to give him a second average pitch, and his changeup has shown signs of life.

Though his progress was obscured somewhat by Heath Hembree's outstanding season, Harrold also established himself as a relief arm to watch. In his first full pro season, he clicked with pitching coach Steve Kline at Augusta, where he recorded a 1.54 ERA and 16 saves before a late-July promotion. His high Class A numbers weren't as pretty, but he gave up eight runs in his first round outings and recovered to post a 2.79 ERA afterward. He also was the best among the bunch of pitchers the Giants sent to the Arizona Fall League. Harrold throws consistent 92-94 mph fastballs from a high three-quarters slot. He commands a lockdown slider that rates as the best in the system. His main needs are to work on a changeup to combat lefthanders and to throw more strikes. If he can do that, he could reprise Sergio Romo's role someday soon in the San Francisco bullpen. Harrold should reach Double-A, if not higher, in 2012.
