Second baseman Christian Colon, rated the Royals' No. 15 prospect by MLB.com, hit the go-ahead home run in the 11th inning Friday as Triple-A Omaha defeated Fresno, 7-6.
After Colon put the Storm Chasers ahead in the top of the 11th, right-hander Louis Coleman retired the Grizzlies in order.
Colon finished the night 3-for-6 with two doubles, three runs and an RBI. The home run was his first since May 7, a span of 127 at-bats.
Colon, the fourth overall pick of the 2010 First-Year Player Draft, is hitting .286 with four home runs and 10 stolen bases. He has drawn 22 walks and struck out 24 times in 62 games.
Left-hander Bruce Chen started the game for Omaha, making his third rehab appearance as he recovers from a bulging disk in his lower back. He threw 70 pitches in three innings, allowing six runs on eight hits and two walks. He struck out one batter.
After Chen left the game, five relievers combined for eight scoreless innings to allow the Storm Chasers to come back and set up Colon's extra-innings heroics.
