Irvin (3-5) allowed three earned runs on five hits and one walk over 6.2 innings Friday in a win over the Giants. He struck out nine.
The nine strikeouts were a career high for the 26-year-old right-hander, who hadn't missed many bats across his first 13 major-league starts. Irvin gave up a solo homer to J.D. Davis in the top of the first inning and a two-run shot to Joc Pederson in the top of the third, but he otherwise looked sharp. He lines up to face the Rockies at Nationals Park next time out.
