Irvin allowed three hits and a walk over five scoreless innings in Tuesday's Grapefruit League game against the Cardinals. He struck out five.
The right-hander appears to be on the outside looking in for a spot in the Nationals' rotation, but Irvin isn't going down without a fight. He tossed 42 of 66 pitches for strikes against a young St. Louis lineup that featured top prospect JJ Wetherholt as well as Alec Burleson and Jordan Walker, lowering his spring ERA to 1.35 with a 15:4 K:BB over 13.1 innings. Irvin still has minor-league options remaining, so despite his strong camp he's likely to begin the year with Triple-A Rochester after Washington added Zack Littell, Miles Mikolas and Foster Griffin to the rotation mix this offseason.
