MIAMI -- The Marlins brought in immediate bullpen depth on Saturday, recalling Andre Rienzo and selecting the contract of Vin Mazzaro from Triple-A New Orleans. The two right-handers have big league experience, and over the next couple of days, they will be relief options for manager Dan Jennings.
Moving forward, the bigger question confronting the organization is how to fill two rotation spots now that Henderson Alvarez (right shoulder inflammation) and Mat Latos (left knee inflammation) are on the disabled list.
Miami has a couple of days to think about it, because those spots come up on Tuesday and Wednesday at Pittsburgh.
Triple-A right-hander Jose Urena is expected to get one of the spots. The other could go to lefty Justin Nicolino, who also is at New Orleans.
"Certainly there are a couple of guys down there that everybody knows," Jennings said. "Those guys will be discussed. You've got some pieces here now in the big leagues who can step in. I think it will be an interesting discussion as to what is going to be the best thing for us right now."
Rienzo, who has pitched for the White Sox, has started at New Orleans, and he could be an option. The right-hander has a 3.15 ERA in seven starts and 40 innings.
Mazzaro, who has big league experience with the Pirates, is being looked at to throw an inning or two. He was 3-1 with a 3.15 ERA for New Orleans.
The Marlins are hopeful Alvarez's injury isn't severe. He went back on the DL two starts after missing more than a month with shoulder inflammation. The Marlins are holding off on having Alvarez, who is 0-4 with a 6.45 ERA, get an MRI exam. They will give it a few days' rest to see how he responds.
Latos has made nine starts and is 1-4 with a 6.12 ERA in 42 2/2 innings. In Spring Training, he had fluid drained from his left knee, which is one reason he got off to a slow start.
The Marlins are hopeful he just needs the 15 days.
"Just try to get it stronger," Jennings said. "These guys are going to take the ball. They're Major Leaguers. They're mentally tough. Now, what they're going to try to do is build some strength in there, and hopefully get the inflammation out and let him build the strength and stamina, so that he can be that guy."
