For the second straight day the Cincinnati Reds will be calling up a pitcher to make their Major League debut. Earlier today it was left-handed pitcher Reiver Sanmartin making his debut. Tomorrow against the Chicago White Sox it’s going to be right-handed pitcher Riley O’Brien.
It’s been 13 months, almost to the day, that the Cincinnati Reds acquired Riley O’Brien. The Reds picked him up on August 28th of 2020 when Cincinnati traded Cody Reed to Tampa Bay.
Riley O’Brien’s 2021 season has been spent in Triple-A with the Louisville Bats. The 26-year-old has made 22 starts and one relief appearance – which came as a 5-inning relief appearance following a rehab appearance start from Lucas Sims.
