MIAMI -- Adding Dan Straily to the rotation means left-hander Dillon Peters will slide into a long relief role, but that may just be temporary.
After their three-game series with the Phillies, the Marlins will have some more roster decisions to make. On Monday, Straily was reinstated from the disabled list, and the corresponding move was placing right-hander Tyler Cloyd on the MLB paternity list, as his wife is having a baby.
"[Cloyd] will have three days, so he will be back after the series, and then we'll have to make a decision of which route we want to go," Marlins manager Don Mattingly said.
Nothing has been determined, but Peters could be the choice to go to Triple-A New Orleans. The left-hander is still being groomed to start. But because Cloyd isn't available for long relief in the next three games, Peters and right-hander Merandy Gonzalez are the two long-relief options.
Gonzalez is the club's No. 13 prospect.
"I think ideally, [Peters'] development should be starting, for sure," Mattingly said.
The Marlins' rotation in the past few games has welcomed back two veterans who opened the season on the disabled list. On Saturday, Wei-Yin Chen (left elbow strain) came off the DL, and Straily (right forearm strain) was reinstated on Monday.
Ideally, the organization would prefer both Peters and Gonzalez starting.
Worth noting:
• First baseman Justin Bour (tight back) was out of the starting lineup for the third straight game on Monday. But Mattingly didn't rule out Bour being available to pinch-hit. Bour took batting practice before the series opener with the Phillies.

• When rookie Lewis Brinson made the Opening Day roster, the organization made a decision to give the 23-year-old plenty of chances to adapt to the big leagues. Brinson entered Monday batting .163 with three home runs and eight RBIs.
"The decision was him making the club out of Spring Training," Mattingly said. "And then it's been, we need to be patient with him, from the standpoint of giving him an opportunity. You can't go two weeks and say, 'It's not going to work.' If we were going to do that, he shouldn't have made the club."
