Fraley (calf) started at designated hitter and went 0-for-4 for Triple-A Louisville on Saturday.
Fraley began a rehab assignment that's expected to last at least four games before he's re-evaluated, per MLB.com. Prior to suffering a calf injury, Fraley was the starting right fielder for the Reds against right-handers, but it's not clear what his role might be when he returns given how well Will Benson has played in his absence.
