Chris Coghlan said Monday that regardless of when the Marlins play the Phillies, every series is "must win."

"I feel like any time you play Philly you have to beat them two out of three, otherwise it's a failure," Coghlan said. "I feel that way with everybody. But when you face guys in your own division, you have to win whether it's June or September."

After a miserable 11-game homestand that saw them go from two games back of the Phillies to being just a half-game out of falling into fourth place, the Marlins might have no choice but to be in must-win mode from here on out. Starting Tuesday, they will face the first-place Phillies four times in three days, including a doubleheader Wednesday. It's the first road series for the Marlins in a stretch during which they will play 16 of 19 games away from Sun Life Stadium.
