MIAMI (CBSMiami/AP) — The 2015 season has gone the exact opposite of what the Miami Marlins had expected after a very positive offseason.

The Marlins placed right-hander Jose Fernandez on the 15-day disabled list because of a right bicep strain Tuesday, and the team’s ace expects to return to the mound later this season.

Fernandez last pitched Friday at Atlanta, leaving after throwing 76 pitches in five innings. He returned to Miami the following day for examination after feeling some discomfort, and says he’s relieved there was no bigger issue.

The Marlins recalled left-hander Justin Nicolino to make Tuesday’s start against the Boston Red Sox and take Fernandez’s roster spot.

Fernandez is 4-0 this season with a 2.30 ERA in seven starts. He didn’t pitch until July while recovering from right elbow reconstruction surgery that was performed in May 2014.
