TORONTO (AP) -- Baltimore closer Jim Johnson has blown more saves in the past two weeks than he did in all of 2012.
Munenori Kawasaki hit a game-ending two-run double off Johnson in a four-run ninth inning, lifting the Toronto Blue Jays to a 6-5 victory over the Orioles on Sunday.
"We should be getting on the plane with three wins here, but I can't hang my head too long," Johnson said. "It's going to hurt for a little bit, and it should."
Johnson (2-5) snapped a string of three straight blown saves by shutting the door on Toronto in Saturday's 6-5 win. But when he opened it a crack in this one, the Blue Jays barged right through.
"He made a lot of good pitches," Orioles manager Buck Showalter said of Johnson. "He just kind of painted himself in a corner there and we just couldn't get it done."
Trailing 5-2 to begin the ninth, the Blue Jays got a leadoff double from Edwin Encarnacion, a single from Adam Lind and an RBI single by J.P. Arencibia.
Brett Lawrie flied out and Anthony Gose walked to load the bases for Mark DeRosa, who made it 5-4 with a fielder's choice.
That brought up Kawasaki, who lined a double up the alley in left-center. Arencibia scored from third and DeRosa raced around from first with the winning run.
"He hit it in the perfect spot," Gibbons said. "Especially with DeRosa running, he definitely hit it in the perfect spot."
Kawasaki tossed his helmet in the air in joy as he rounded second base and was mobbed by his teammates as DeRosa slid home without a throw.
The blown save was Johnson's fourth of the season and fourth in five chances. He went 51 for 54 in save chances last year.
"I'm going to keep working," Johnson said. "That's all I can do is keep plugging away and trusting that I can do it. I know I can. It's just that the results haven't been what I've wanted them to be lately."
Steve Delabar (4-1) got the win despite allowing Matt Wieters' two-run double in the ninth.
Baltimore's Adam Jones homered for the fourth consecutive game and Wieters had four hits and three RBIs for the Orioles.
"It's a tough loss," Wieters said.
Lawrie appeared angry at third base coach Luis Rivera for not telling Lind to tag up after his ninth-inning fly ball. Lawrie later exchanged words with Gibbons in the dugout.
"He got a little heated, I got a little heated," Gibbons said. "That's over. It's no big deal, those things happen."
Jones hit a one-out solo homer to left off Aaron Loup in the seventh inning, his 10th. The home run was his ninth at Rogers Centre since the start of the 2012 season, the most by any opposing player.
Jones has hit safely in 16 straight games against Toronto, dating to Aug. 24, 2012. His four-game homer streak is the longest of his career. He's had three-game streaks three times.
Orioles starter Miguel Gonzalez allowed one run and four hits in 5 2-3 innings. He walked three and struck out a season-high seven. The right-hander, who landed on the disabled list earlier this month with a blister on his thumb, had not won since beating the Blue Jays in Baltimore on April 23.
Nick Markakis was thrown out at the plate trying to score from first on Jones' double to left field in the first, with shortstop Kawasaki making the relay throw to the plate.
The Orioles took the lead in the second against Jenkins. Chris Davis led off with a double, went to third on J.J. Hardy's single and scored when Wieters doubled to left. One batter later, Hardy scored on Danny Valencia's groundout.
The Blue Jays cut the deficit in half in the fourth when Lind scored on Lawrie's sacrifice fly.
Starting for the second time this season, Jenkins allowed two runs and eight hits in five innings. He walked three, two intentional, and struck out two.
"He kept us in the game, got some big outs in a couple of situations where the game could have got out of hand," Gibbons said.
Baltimore loaded the bases against Thad Weber in the sixth but Manny Machado grounded into an inning-ending double play.
Tommy Hunter replaced Brian Matusz after Melky Cabrera's two-out walk in the seventh. Singles by Jose Bautista and Encarnacion loaded the bases for Lind, but he flied out on the first pitch.
