Martin Prado started at first base on Sunday for the second time in the Orioles series as Freddie Freeman remained sidelined with an injured finger.
"We tried a different treatment, and hopefully [Freeman will] be ready by Tuesday," manager Fredi Gonzalez said.
Freeman has been out of the lineup since last Tuesday, missing five games. He has just four hits in his past 18 at-bats.
