Frias (5-5) didn't give up a run despite allowing 10 baserunners -- seven hits and three walks -- in five innings during Thursday's 4-0 win over the Cubs. He struck out five. Frias had previously made four winless starts (with an 0-3 record) in June, and yet he put more men on base Thursday than he did in three of those games. He's also failed to complete six innings in any of his last three starts. Frias represents a low-end starting option entering Tuesday's outing in Arizona.
