Johnny Cueto’s return is still at the very least a week away, meaning Tony Cingrani could still have two starts before the Reds have to make a decision on what to do with their rotation.

Cueto is scheduled to pitch Tuesday in Dayton and his next scheduled start would then be on Sunday, May 19. Whether that start is in Philadelphia or elsewhere is still to be determined.

At that point, the Reds could be forced to make the decision between Mike Leake and Tony Cingrani. Cingrani lasted just four innings in Friday’s start, allowing back-to-back home runs to Jean Segura and Ryan Braun in the fourth inning. It was Cingrani’s shortest outing in his five-starts in the big leagues.

Cingrani, whose ERA rose to 2.86 with the outing, has allowed at least one home run in four of his five starts, including two in each of the last two starts.

“You can get by with basically one pitch -- he’s throwing 95 percent fastballs -- but the second time through and third time through, it’s even tougher because they know the action on your ball,” Reds manager Dusty Baker said. “He’s going to have to come up with a secondary pitch -- especially against a team like that team. They can hit that fastball.”

According to FanGraphs.com, Cingrani has thrown 83.3 percent fastballs, 10.6 percent sliders and 6.1 percent changeups in his five starts this season. Of starters who have thrown at least 20 innings this season, only the Nationals’ Ross Detwiler (90.8 percent) and the A’s Bartolo Colon (89.2 percent) throw their fastball more. Last season, among qualified starters, Cleveland’s Justin Mastson threw the highest percentage of fastballs, 80.7 percent.
