"Good," said manager Bobby Valentine. "He hit a 94-mph fastball. He was real aggressive at the plate. He got all of his work. He battled a walk. It sounds like he had a good night."
Youkilis took Thursday off and will play third base for Pawtucket on Friday after serving as the designated hitter in his first game.
Could Youkilis resurface during the three-game series at Philadelphia or is it more likely he rejoins the team in Baltimore for a series that starts Monday?
"It's on him," said Valentine. "When he's ready, he'll probably give us a call."
Will Middlebrooks, the club's top prospect filling in for Youkilis, has cooled off following a red-hot start. The third baseman entered Thursday's game with two hits in his last 12 at-bats.
