Muncy (side) is starting at third base and batting fifth Tuesday against the Padres, Eric Stephen of SBNation.com reports.
The third baseman was scratched from the lineup Sunday against the Rockies due to side soreness, but he's ready to play following Monday's team off day. Muncy started off September by going 0-for-11, but he has a .286/.446/.643 slash line with three doubles, four homers, 11 RBI and 12 runs in his past 14 games.
