McLain (calf) served as the designated hitter and went 2-for-4 with a double and a run scored in a rehab game for Triple-A Louisville on Saturday.
McLain made his second rehab appearance with Louisville, after he started at shortstop and played six innings Friday. He can be activated from the 10-day injured list at any point and could be a candidate to rejoin the Reds prior to the start of a three-game set against the Guardians on Monday.
