Manager Buck Showalter has plenty of options to choose from.
Reliever Dana Eveland, recently signed veteran Jamie Moyer, Triple-A standout Chris Tillman, freshly assigned Miguel Gonzalez, recovering starter Zach Britton and even Jake Arrieta, who was moved to the bullpen on Saturday, are legitimate possibilities.
"We'll see," Showalter said. "We've got some depth to pick from there, if we have a need. I hope we don't have a need. Obviously we're going to need a fifth starter."
Eveland and Gonzalez, who have both performed well in long-relief roles with the Orioles, were considered for last Saturday's start but were needed out of the 'pen leading up to the weekend. Tommy Hunter was ultimately named the starter and allowed three runs in seven innings.
Tillman has posted a 4.01 ERA in 67 1/3 innings with Norfolk, and a Saturday start would come after four days rest on his current schedule.
Britton could be ready to make his return from a left shoulder impingement that has kept him on the disabled list since March. After allowing four runs on seven hits in six innings during his first start at Norfolk on June 5, he gave up three on seven hits while lasting just 4 2/3 on Sunday.
Moyer, a 49-year-old left-hander who was signed to a Minor League contract on Wednesday, threw five shutout innings in his debut with Norfolk on Saturday. He allowed only one hit and didn't walk a batter while striking out five.
Showalter said Moyer's outing could have been even stronger were it not for a pair of fielding errors made behind him, but the skipper did not offer any comment on what the start means for his future with the team.
Executive vice president of baseball operations Dan Duquette has said that Moyer's time with Norfolk is considered an audition for the Major League club.
