Lowder allowed one hit and struck out two over a scoreless inning of relief in Monday's Cactus League game against Milwaukee.
Lowder, the Reds' first-round pick in the 2023 First-Year Player Draft, was making his first career spring start. He pitched the seventh inning, with the lone hit he allowed a broken-bat single, per C. Trent Rosecrans of The Athletic. The right-hander threw 13 pitches (10 strikes), with both of his punchouts coming on called third strikes.
