TORONTO - It must be contagious.
The San Francisco Giants came to Rogers Centre and played the way the Blue Jays were playing earlier in the season.
The Giants had trouble catching, throwing and hitting the ball, and they went down to a crashing defeat for the second game in a row to the Blue Jays, 11-3 before a crowd of 32,863 on Wednesday.
Ramon Ortiz (1-1) pitched seven innings to earn the win and Adam Lind and J.P. Arencibia each hit two-run homers.
The Blue Jays have won four in a row for the first time this season.
"We really are swinging the bats now, we are on a nice little roll," Blue Jays manager John Gibbons said.
"Groundhog day," Giants manager Bruce Bochy said. "That's unlike us. I can't think back to when we had two games, identical games, where we made mistakes there in the first inning."
The Blue Jays scored five unearned runs in the first inning on Wednesday after scoring six - three unearned -- in the first inning of Tuesday's 10-6 win. The Giants made two errors each time.
"The big number there killed us, took us out of our game. It's hard to explain. But it happened and now we've got to move on," Bochy said.
"They made a couple of errors in each game and we took advantage of them," Gibbons said. "In a lot of ways that's what was killing us earlier in the season, we benefitted from it tonight."
The Blue Jays' (17-24) sweep of their two-game set with the 2012 World Series champion Giants (23-17) gives them two consecutive series wins for the first time since May 16-20, 2012. They took two of three from the Boston Red Sox over the weekend.
Ortiz, who turns 40 on May 23, allowed six hits and one run to earn his first major-league win since Sept. 11, 2011, when he was with the Chicago Cubs.
Ortiz, who was making his second start since being recalled from Class AAA Buffalo last week, had not won as a starter in the majors since April 17, 2007, as a Minnesota Twin.
"He's doing a great job," Gibbons said. "What's that, 12 innings, two runs he's given up? He probably never envisaged he'd be in this situation where he would be getting starts in the big leagues again. He came up earlier in the year as a long guy. But now he's getting the opportunity to start, he's taking advantage of it."
"I see eight runs on the board, I said okay, I have to throw strikes, I have to make pitches and let the guys swing the bat and that's what they did tonight," Ortiz said. "I know I can pitch, I know I can throw strikes, I knew I had an opportunity to come back here.
"The key right now is that I have a lot of confidence in all my pitches, my changeup, my slider, my two-seamer and four-seamer."
Giants' starter Ryan Vogelsong (1-4) allowed eight runs, but only three were earned, in two innings. He allowed six hits, including both homers.
"They have a good lineup, they swing the bats," Vogelsong said. "From everything I've seen from earlier in the season they were scuffling a little bit but all those guys are really good hitters. It's not all that surprising."
Reliever Chad Gaudin allowed four hits and three runs in 3 1/3 innings before leaving in the sixth after Colby Rasmus' RBI double.
Toronto reliever Mickey Storey allowed two runs in the eighth on a walk and two hits, including Buster Posey's RBI double, and the other run scored on Brett Pill's sacrifice fly.
Marco Scutaro singled in the ninth to extend his hitting streak to 14 games, but Pablo Sandoval had a seven-game hit streak end for San Francisco.
The Giants scored first after Angel Pagan led off the game with a double, was sacrificed to third by Scutaro and came home on Sandoval's sacrifice fly to center.
Two Giants' errors in the home first led to five unearned runs. Scutaro dropped Jose Bautista's pop to second, Edwin Encarnacion walked, and both scored when Pagan lost Arencibia's drive to center for a two-base error. Lind then hit his third homer of the season. Brett Lawrie singled, Rasmus was hit by a pitch and Emilio Bonifacio singled in the fifth a run.
It was the first time Toronto had batted around in consecutive first innings since April 10-11, 1994, against Seattle and Oakland.
"Our outfielders seemed like they were struggling at times picking up the ball," Bochy said. "The ball was carrying well. Still, we're disappointed we came in here and put together two games like this. It's not our type of baseball."
In the second, Melky Cabrera doubled and scored on Bautista's single. Arencibia hit his 10th homer of the season for an 8-1 lead.
A pair of walks, Bautista's RBI double and Encarnacion's sacrifice fly in the third against Gaudin made the score 10-1.
