Meanwhile, Workman, a 25-year-old who was making his seventh major league start, was perfect through four innings Tuesday.

With one out in the fifth, Workman allowed his first base runner, permitting a one-out walk to Nelson Cruz, his 14th batter faced. Cruz was quickly doubled off when J.J. Hardy popped up to second baseman Dustin Pedroia and Cruz inexplicably dashed to second, forgetting the number of outs -- and was easily doubled off.

“I think so. That's the way it looked to me,” Showalter said. “There's a time and place [to address it].”

Cruz said: "I missed the outs. It's no excuse. I should know better. It shouldn't have happened."

The Orioles finally got a hit against Workman with two outs in the sixth when Flaherty singled to center. The Maine native made sure Red Sox Nation wouldn't have more no-hit history against the Orioles.

The Orioles have been no-hit only six times in modern franchise history; the past two were by the Red Sox: Clay Buchholz in 2007 at Fenway Park and Hideo Nomo in 2001 at Camden Yards -- the only no-hitter in the stadium's 23 seasons.

Workman (1-0) ended up throwing a career-high 6 2/3 innings, striking out four while walking one.

And that was too much for Tillman and company.

“He threw the ball well, and I think, as an opposing pitcher, you've got to do your job and make pitches because he is going to be tough,” Tillman said. “He's tough.”
