Miami split those matchups, winning the first two while dropping the final two. In the 25 1/3 innings those four pitched, the offense scored 10 runs -- nine earned.
Entering Friday, the Marlins had the lowest batting average (.227) of all big league teams, just behind the Nationals (.228), and the third fewest runs scored (114) against southpaws.
The Marlins didn't face a lefty starter in Friday's 3-2 loss to the Rockies, but Colorado's lefty closer Rex Brothers pitched a 1-2-3 ninth inning with two strikeouts.
"Statistically, we haven't done really well against left-handed pitching, but I thought despite losing three out of four to the Dodgers we swung the bat all right," Marlins manager Mike Redmond said. "We didn't get a ton of hits in those games, but I thought even with [Zack] Greinke, we swung the bat really well. We just didn't get a whole lot to show for it."
Redmond believes his team had a good approach -- pointing to several long outs and line drives the offense couldn't capitalize on. With several rookie starters, the offense continues to be a work in progress.
"Offensively, we have some challenges there and left-handers have been a bigger challenge than righties," Redmond said. "Guys' approaches have been solid, and I think as we face more and more lefties down the road we'll continue to get better."
