"I felt like I made my pitches when I had to," said Tillman, who will get at least one more start before his season ends. "They hit, I think, four ground balls and got three runs out of it. That kind of stuff happens. I guess I work on the bad and continue the good and go from here."
The Orioles' offense, which had scored nine total runs in its past four losses, was stymied by Toronto's David Purcey, who had allowed 22 earned runs in 31 1/3 innings in the majors this year (6.32 ERA).
Purcey (1-2) gave up just one run - a two-out RBI single by Felix Pie in the second - and allowed only four hits through 7 2/3 innings. At one point he retired 10 straight before loading the bases in the eighth on two walks and a hit.
It was the Orioles' best threat, but reliever Shawn Camp induced Melvin Mora into an inning-ending groundout.
"That was a pivotal part of the game, as far as trying to get back in it," Trembley said. "We did not have anything as far as a scoring opportunity up to that point in time. A two-out hit there certainly would have been welcomed and would have got us back in the game."
Ultimately it didn't matter because the Orioles' bullpen allowed five runs, four charged to struggling right-hander Bob McCrory.
"The bad thing was, including myself, we should have scored more runs to help the pitchers," Mora said.
Note: Trembley said right fielder Nick Markakis, who has been in a prolonged slump, might not start tonight. Markakis has played in every Orioles game this year and started all but one, June 21 at Philadelphia. He entered that game in the eighth inning.
