Earlier in the day, the Orioles received the uplifting news that the season-ending injury to Manny Machado likely will not require surgery and he could be ready for spring training.
Playing without their All-Star third baseman in the starting lineup for the first time this season, the Orioles scored three runs or fewer for the seventh time in their past 10 games. They have four runs or fewer in six straight games and 17 of their past 21.
In the process, the Orioles are five games above .500 for the first time since May 29.
The announced 16,772 gave Machado a standing ovation when he was shown on the video board in the middle of the fifth inning. Machado tipped his cap to fans, but there was little for the fans to cheer for after that moment.
After back-to-back solo homers by Brian Roberts and Nate McLouth put the Orioles up 2-1 in the third, the Orioles were scoreless for seven innings.
"For some reason, our consistency offensively wasn't there, as it should have been at the end," McLouth said. "The pitching has really pitched well, it seems like, for a while now. We weren't able to consistently score enough runs. We had plenty of pitching tonight, plenty in Tampa. We didn't do enough offensively so it's disappointing, because that's the goal you come into spring training with and we're not going to be able to do that."
The Orioles wasted a quality start from right-hander Chris Tillman, who went seven or more innings for the sixth time in his last seven starts, allowing just one run on five hits over seven innings, tying a career-high with nine strikeouts and recording just one walk.
Tillman received a no-decision, but he became the fifth Orioles pitcher to reach 200 innings in a season since 2001. He joined Jeremy Guthrie (2009, 2010 and 2011), Daniel Cabrera (2007), Rodrigo Lopez (2005) and Sidney Ponson (2004). He also became the first Orioles pitcher 25 years old or younger to reach 200 innings since Ponson, who was 22 when he pitched 210 innings in 1999.
The Blue Jays tied the game in the eighth when Reyes led off the inning with a single off rookie right-hander Kevin Gausman. He moved to second on a sacrifice bunt and on to third on a wild pitch.
After Gausman struck out Brett Lawrie for the second out, left-hander Brian Matusz yielded a run-scoring bloop single to shallow right field to pinch hitter DeRosa to tie the game.
After putting runners on first and second to open in the fourth inning, Tillman faced just one batter over the minimum for the rest of his outing, retiring 11 of the final 13 batters he faced.
Tillman allowed his only run in the second inning. The Blue Jays (71-85) put runners at second and third with one out on Adam Lind's leadoff single and a one-out double by Anthony Gose. Ryan Goins' two-out infield single to shortstop scored Lind for an early 1-0 lead.
