The Braves called up right-hander Peter Moylan, first baseman Lyle Overbay, outfielder Jose Constanza and catcher J.C. Boscan from Triple-A Gwinnett. They also added utility player Jeff Baker, who was acquired in a trade with the Tigers on Friday night.
Manager Fredi Gonzalez said he's happy to have more options at his disposal.
"You can mix and match, and the matchups we have, use them to our advantage," Gonzalez said. "It's good to have [guys] on the bench."
Perhaps most prominent of Saturday's callups was Overbay, who signed a Minor League contract with the Braves on Aug. 20 with the intention of joining the team Saturday. Overbay hit .292 with a .367 on-base percentage for the D-backs before being released last month.
Overbay said he's excited to join a team in the playoff race.
"It's a chance to win, and those are opportunities that don't come very often," Overbay said. "This was probably my best opportunity to get to the playoffs so it made my decision easy."
Overbay's only playoff experience came last year with the D-backs. Before that, the 35-year-old veteran had played for teams not in contention in his 12-year career.
