Last Wednesday at Cincinnati, he pitched 7 2/3 scoreless innings, allowing just two hits with four walks and three strikeouts. It was the longest outing in which he did not allow a run since Aug. 8, 2015 on the road against the Angels.

Jiménez ranks 10th on the all-time wins list among Dominican Republic-born pitchers with 109 career victories. He is eighth on the all-time starts list among Dominican-born pitchers and 11th in innings pitched.

Orioles starters have recorded 10 quality starts in 17 games. That is tied for fourth in the American League and for eighth in the major leagues.
