The Reds made a significant addition to their rotation today by trading for Mat Latos, but ESPN's Buster Olney says (on Twitter) that they are still looking for ways to upgrade their pitching staff. They could still add another starter at some point.
Latos figures to join Johnny Cueto, Homer Bailey, Bronson Arroyo, and Mike Leake in Cincinnati's rotation next season, with Travis Wood in reserve as the sixth starter. Cueto finished the season on the disabled list with a shoulder strain though, and Leake was the only other member of the rotation to finish the year with an ERA under 4.40. Plans to move Aroldis Chapman into the rotation hit a snag when a shoulder issue kept him out of winter ball.
The Reds were said to have interest in Jair Jurrjens, Gio Gonzalez, and James Shields recently, but it's tough to see them swinging another trade of that caliber after landing Latos. Unsigned free agents like Zach Duke and Rodrigo Lopez could serve as decent depth pieces on minor league contracts.
