LaMacchia was 8-2 with 135 strikeouts in 91 1/3 innings as a high school senior. The St. Louis Cardinals took him in the 18th round of the 2000 amateur draft but he continued on to college. He went 5-2 with a 4.72 ERA as a freshman in 2001. In 2002, the sophomore improved to 11-2, 3.38 and had the lowest ERA of FSU's starting pitchers. He was 8th in the Atlantic Coast Conference in ERA and in the top 10 in victories. During his junior season, the right-hander was held to two games by injury (1-0, 0.00, 1 H, 11 K in 9 IP). The Texas Rangers chose him in the 21st round of the 2003 amateur draft.

The Florida native pitched one game for Italy in the 2006 World Baseball Classic. He relieved Kasey Olenberger with a 4-0 deficit entering the 6th.
