Irvin (4-7) earned the win during Friday's 5-1 victory over Houston, allowing one run on three hits and one walk with four strikeouts in six innings.
The lefty was locked in a pitcher's duel with Jose Urquidy until Irvin surrendered a run in the fifth inning following a leadoff Chas McCormick double. Oakland eventually rallied to give the 28-year-old his second win in three starts, during which he's pitched to a 1.80 ERA across 20 innings. Irvin concludes the first half on a high note and possesses a 3.21 ERA and 1.10 WHIP with 62 strikeouts in 95.1 innings across 16 starts.
