Reds starting pitcher Mat Latos left his game vs. the Cubs on Tuesday with a strained left calf. He is day to day.

There were two outs in the fifth inning when Latos made a first-pitch delivery for a ball to Alfonso Soriano. Latos appeared to have some discomfort and was visited at the mound by manager Dusty Baker, pitching coach Bryan Price and trainer Paul Lessard.

Following several moments, Latos walked to the dugout and looked disgusted. Expected to work six innings, he finished with three runs (two earned) and four hits allowed over 4 2/3 innings. He walked two and struck out two.
