Of the group, Capps is most likely to get a quick callup. The 25-year-old had an injury-plagued 2014 season, appearing in 17 games and stiking out 25 in 20 1/3 innings for Miami. He missed substantial time due to a right elbow sprain.
"Capps was a tough one," manager Mike Redmond said. "This guy has big league time. I think, for him, it's a matter of going down and being more consistent. He has big league stuff and has been there.
"We talk about our depth, to have a guy like him in our system in Triple-A. He can pitch in the big leagues and get guys out. We know that."
In 4 2/3 innings of Grapefruit League action, Capps had sporadic command. He struck out six, but walked four and hit two batters while giving up five earned runs (9.64 ERA).
"Last year, he went down and he worked on his delivery and being more consistent," Redmond said. "He came up and was effective and then he got hurt. Right now, what I see is just command. He needs to go down there and be more consistent with his command. When that happens, he will be ready."
• Christian Yelich was given another day to rest a small blister on his right palm Tuesday. The left fielder has sat out three straight games as a precaution. Yelich did take batting practice, and he is scheduled to make the trip to Lakeland, Fla., on Wednesday when the Marlins face the Tigers (1:05 p.m. ET, MLB.TV).
• David Phelps will make the start against Detroit on Wednesday, while Dan Haren will stay back in Jupiter and pitch in a Minor League game. Phelps, projected to be a long reliever, will get another chance to build up innings. Haren, meanwhile, is already close to being ready for the regular season.
• Yelich, Marcell Ozuna, Don Kelly, Reid Brignac, Donovan Solano and Jhonatan Solano are scheduled to make the trip to Lakeland.
