With the Fort Myers Miracle, he compiled a 7–2 record with a 4.83 earned run average in the first half of the 2008 season—helping his team capture the Florida State League (FSL) first-half West Division title. Guerra's first start in the second half of the 2008 season (Tuesday, July 1) was a 4–0 complete game shutout of the Tampa Yankees.

It marked the first shutout of Guerra’ professional career. For the second half, he went 4–7 with a 6.08 ERA in 13 starts.
