Derek McCallum was an All-American infielder.
McCallum hit .469 as a high school junior and was All-State as both a junior and senior. He also played hockey four years in high school. His hometown Minnesota Twins picked Derek in the 50th round of the 2006 amateur draft but he opted for college.
Derek hit .340/.379/.444 as a college freshman then fell to .291/.352/.398 as a sophomore. He spent the summer of 2008 with the St. Cloud Riverbats and hit .328 to finish second in Northwoods League MVP voting. He had a huge junior year, putting up a .409/.484/.741 line with 18 home runs. He led the Big Ten Conference in hits (95), home runs and RBI (86) and was second in average. He tied Rich Poythress for second in NCAA Division I in RBI, one behind leader Paul Goldschmidt. Baseball America and the American Baseball Coaches Association named him as the All-American second baseman. Collegiate Baseball chose Pitt's Chris Sedon instead to prevent a sweep. The Twins again picked the hometown product, this time in the fourth round of the 2009 amateur draft. He was the first position player they chose after four pitchers in a row.
McCallum broke into pro ball with the Elizabethton Twins in 2009 and hit .241/.310/.382 with 38 runs and 38 RBI in 57 games. He led Appalachian League second basemen in putouts (136) and double plays (44). Battling a wrist injury in 2010, he had only played 25 games through early July, hitting .213/.317/.303 for the Beloit Snappers.
