Dunn (1-1) earned the win Saturday, allowing one run on three hits and four walks over five innings against Pittsburgh. He struck out four.
Dunn surrendered a first-inning double to Tucupita Marcano and a solo home run from second baseman Rodolfo Castro with one out in the fourth. Due to a shoulder injury, the righty has only had two other outings this season, giving up a combined eight runs in 8.1 innings in those games. The 26-year-old's numbers were a bit more serviceable during his previous two seasons with the Mariners, recording a 3.75 ERA and 1.31 WHIP over 11 starts in 2021 and a 4.34 ERA and 1.36 WHIP over 10 starts in 2020.
