ST. PETERSBURG, Fla. -- Roy Halladay has put last season's rough finish behind him.
"I haven't really thought about it, but it was a tough end of the season last year," Halladay said. "It's nice to have it over with."
Halladay (1-0) had gone winless in seven starts - including his final six last year - since beating Baltimore on Aug. 20. He gave up three runs, seven hits and three walks over seven innings. He struck out seven.
"Doc battled," Toronto manager John Gibbons said. "It wasn't an easy day for him."
Janssen, moved from a starting role to the bullpen this season, has allowed one hit in 5 2/3 scoreless innings spanning three appearances.
"He's gaining confidence," Gibbons said. "The bottom line, he's got everything he needs. His stuff's there. It was a big day because we needed him."
Janssen got the save opportunity because closer B.J. Ryan pitched the previous two days.
Kazmir's first eight outs came on strikeouts, including one stretch when he struck out six consecutive batters to set a team record. The left-hander, who ended the 2006 season on the disabled list with a shoulder injury, is winless in seven starts dating to a 2-0 shutout of Boston last July 3.
"I really got into a groove early," Kazmir said. "There's just a couple of pitches I'd like to have back. There's some things I can take out of today, positive things. Being aggressive and attacking the hitters."
Wells put the Blue Jays up 1-0 with a homer in the first. Tampa Bay tied it in the second when Delmon Young scored from third after Elijah Dukes was caught leaning the wrong way at first by Halladay and was later tagged out in a rundown while attempting to steal second.
Baldelli gave the Devil Rays a 2-1 lead when he homered on a 1-2 pitch leading off the fourth.
Toronto third baseman John McDonald, filling in for the injured Troy Glaus, saved at least one run when he made a diving catch of Duke's grounder with runners on the corners later in the fourth to start an inning-ending double play.
"You don't want to impact the game in a negative way," McDonald said. "You want to contribute and do your thing and hopefully the team doesn't miss a beat without Troy in there."
McDonald had a two-out single in the fifth and scored when Johnson followed with a three-run homer to make it 4-2.
"The two-out inning really hurt us," Tampa Bay manager Joe Maddon said. "Other than that, we'd be celebrating right now."
"I think they beat us with their gloves as much as anything," Maddon said. "Not taking anything away from Halladay, but I liked our at-bats against him a lot. I thought we extended him really well. I have no complaints. I thought we played really well."
Hill and Gregg Zaun had run-scoring singles in the eighth to extend Toronto's advantage to 6-3.
