When healthy, this rotation is arguably the deepest in baseball. Unfortunately for the Reds, health is a big concern for the team right now.
Ace Johnny Cueto has dealt with injuries to his side since the 2012 postseason, and he was limited to only 11 starts last season. Tony Cingrani put up great numbers in Cueto's place last season, but he missed some time with a back injury.
Right now, two other pitchers are dealing with injuries. Mat Latos, who has turned into an ace since coming to Cincinnati, had both elbow (bone chips) and knee surgery (torn meniscus) since the end of last season. Now Mike Leake is dealing with an abdominal injury, according to MLB.com's Mark Sheldon. Leake will take some time off and hope that it doesn't become a bigger issue.
Homer Bailey is the only pitcher who hasn't had any injuries in recent seasons. With Latos' status uncertain, Sheldon reported that manager Bryan Price is going to take his time before he sets the rotation.
If Latos is ready for Opening Day, he and Cueto could flip spots in the rotation. If he is still dealing with his knee injury, look for Cingrani and Leake to swap spots in order to match up with the St. Louis Cardinals.
Cincinnati's rotation has the ability to eat up innings when healthy. Cueto, Latos and Bailey have all topped the 200-inning mark at least once in their careers. Leake threw 192.1 innings last season and should make a run at 200 this year. Cingrani will likely be limited to around 170 innings, but nothing has been announced.
Health is a big concern in the rotation. This team doesn't have much depth in the minors, so it will be hoping that all of the injuries will be healed by March 31.
