What's the rotation shaping up like?
Great question, because so much of how the rotation shapes up depends on Jose Fernandez. There is no question Fernandez is the ace of the staff, but that doesn't automatically mean he will pitch on Opening Day. Why?
As you know, Fernandez has an innings range of around 180. So how will he reach that? One possibility could be not starting Opening Day, and perhaps starting him off in the back of the rotation. This scenario could happen.
The way things may map out is for Fernandez to have fewer starts in April, and increase his availability later on in the season. Because Wei-Yin Chen started on Wednesday, the lefty actually is lined up every fifth day to start on Opening Day, which is April 5 against the Tigers at Marlins Park.
Who do you see replacing Carter Capps in the 'pen?
You're not going to replace the pure, powerful stuff of Capps. There aren't many who regularly throw 100 mph with a wipeout slider. But there still are power arms in the back end. A.J. Ramos, of course, will be the closer. For the eighth inning, you are looking at lefty Mike Dunn and right-hander Bryan Morris. Non-roster invitee Dustin McGowan is getting a long look to be a part of that role. Kyle Barraclough and Brian Ellington may emerge at some point during the season, if not directly out of camp.
How much will Bour improve against lefties now that hitting coach Barry Bonds is mentoring him?
Bour is getting chances against lefties. But no matter who is mentoring, it's the players who either perform or not. Bour had 68 at-bats and hit .221 against lefties last year. He hit lefties pretty well in the Minor Leagues, but in the big leagues, it's a different challenge.
The question will be if the Marlins are patient with Bour against lefties or just selectively look to use him in those games, or go more with a platoon at first.
