In this corner, Drew Pomeranz, the former first-round draft pick out of Ole Miss, now pitching for the Colorado Rockies. And in this corner, the Miami Marlins, a two-time world champion. Well, Monday night’s matchup in Coors Field could have been hyped that way, but in reality it didn’t figure to be much of a fight. The Marlins, currently one of the worst teams in baseball, went into that game in the throes of a 37-inning scoreless drought. Pomeranz, recalled from the minors on Sunday, had an 0-3 record and an 8.76 ERA in three big league starts this season. Ding. The Marlins came out swinging, scored in the first inning (former Mississippi Braves shortstop Ed Lucas tallied the run) and won the game 3-1. Pomeranz lasted just 4 1/3 innings and took the loss. The big left-hander, drafted by Cleveland in 2010, was rushed to the majors by the Rockies after they got him in the Ubaldo Jimenez trade in mid-2011. The results have been disappointing. Entering this season, Pomeranz was 4-10 with a 5.01 ERA in 26 big league starts. He seemingly has gone backwards in 2013. P.S. Possible defining moment for Atlanta’s season: Former M-Braves star Jason Heyward’s diving catch in center field in the pouring rain to close out Monday’s 2-1, come-from-behind win over the New York Mets. If you didn’t see the play, look for it.
