Manager Buck Showalter said the team will not begin his three-day paternity leave until Tuesday, and the Orioles will have Tommy Hunter available out of the bullpen if the need for a long reliever were to arise on Sunday.
"We're fine," Showalter said. "Everybody is available in the bullpen today."
Once Eveland officially begins paternity leave, the O's will be able to replace him on the 25-man roster for up to three days.
Showalter said one option is to bring back reliever Matt Lindstrom, who has been on the 15-day disabled list since May 11 with a partially torn ligament in his right middle finger.
Lindstrom made a pair of rehab outings in the Gulf Coast League before moving to Double-A Bowie and pitching for them on Friday. He is scheduled to throw again on Sunday.
"It depends on what everybody thinks, if Lindstrom is ready or not," Showatler said. "We're not going to do it just because it's convenient. I know we've obviously got the staff there, and one of the scouts is going over to the Bowie game to help make that decision. So that'll probably be something that'll be decided after he pitches today."
