If it weren't for the indoor facilities at Camden Yards, right-hander Chris Tillman probably wouldn't have lasted six innings in the Orioles' 1-0 loss to the Boston Red Sox on Tuesday.

During a 1-hour, 18-minute rain delay, the second weather-induced break of the game, Tillman pitched a pair of simulated innings indoors, allowing him to obtain a quality start when play resumed.

Tillman threw 100 pitches in six innings, and he surrendered just one run despite allowing seven hits and three walks.

“I wouldn’t say difficult, just different,” Tillman said of the rain delays. “I think it definitely helped me being able to get up two or three times. ... You kind of just take it like it was another inning.”

Tillman, who had failed to record more than three outs in two of his previous four appearances, worked into trouble in nearly every inning Tuesday. The Red Sox capitalized with a flare single by Mike Napoli in the third inning to knock in their only run, but it was Tillman’s only blemish of the night.

The Red Sox loaded the bases with no outs in the fourth, but Tillman struck out Brock Holt and induced a double play to escape the jam.

“I was able to execute pitches when I needed to when I got into trouble,” Tillman said. “Later in the game, I was executing most of my pitches. So it was good to see it coming. Especially felt better as I went, so that’s promising.”

Tillman was tagged with the loss, though, because Red Sox starter Brandon Workman only allowed one hit to the Orioles through 6 2/3 scoreless innings.

Without the indoor mound, however, Tillman likely wouldn’t have had a chance to last deep into the game or compete for a win.

“You always expect to pitch well,” he said. “Tough conditions tonight for both teams, but you won’t hear any excuses from us, and I’m sure you won’t from them either.”
