The Reds selected Lowder's contract from Triple-A Louisville on Friday.
Lowder is set to make his major-league debut in the second game of Friday's doubleheader against the Brewers. The No. 7 overall pick in the 2023 First-Year Player Draft, Lowder has collected a 3.64 ERA, 1.15 WHIP and 113:24 K:BB over 108.2 innings across three levels in 2024 and just made his Triple-A debut last week. He's now set for his major-league debut and should be given an opportunity to stick in the Reds' rotation for the remainder of the season.
