TORONTO -- A rare start at designated hitter gave Colby Rasmus the chance to work on his hitting and his tan, all at the same time.

Rasmus, Edwin Encarnacion and Yunel Escobar all homered off Detroit newcomer Anibal Sanchez, leading the Toronto Blue Jays over the Tigers 5-1 Saturday.

Rasmus went 2 for 3 with three RBI in his first game this season as Toronto's DH, adjusting quickly to not playing the outfield.

"It definitely was weird in the beginning," Rasmus said. "I just stayed focused on the game and watched [Sanchez] pitch and what he was trying to do with the hitters so it would give me a better chance when I got up there."

Rasmus stayed comfortable between at bats by settling down in a sun-kissed spot at the edge of Toronto's dugout.

"I sat up on that top step, that sun was beating down a little bit so it kept me warm," he said.

Henderson Alvarez (7-7) pitched seven innings for the win.

"I felt great," Alvarez said through a translator. "All of my pitches were down in the zone and every pitch I threw was working."

Facing Detroit for the first time, Alvarez (7-7) allowed one run and five hits. He walked two and struck out four.

"I was really, really impressed," Tigers manager Jim Leyland said. "He's got a real live arm."

Detroit's Brennan Boesch was also impressed, mostly with Alvarez's velocity.

"He had a fastball that was more electric than we anticipated," Boesch said.

Alvarez's only walks were issued consecutively, to Miguel Cabrera and Prince Fielder in the sixth, but Delmon Young and Boesch both flied out to end the threat.

J.A. Happ worked the final two innings for Toronto.

The Tigers have lost three straight and four of five after a five-game winning streak that briefly lifted them into first place in the AL Central, but Boesch said the Tigers are too "battle-tested" to worry about slipping back to second place.

"No one in here is going to be shaken by a couple of games that don't go our way," Boesch said.

Detroit, which had not lost three straight since June 3-6, has scored just nine runs in its past four defeats.

"Right now, you can't sugarcoat it, we're not hitting," Leyland said. "We're not driving in runs and we're not hitting."

Sanchez, acquired from Miami earlier in the week along with infielder Omar Infante, gave up five runs and eight hits in six-plus innings. The three homers he surrendered were a season-high.

While Sanchez's debut didn't go as planned, Leyland wasn't worried.

"He knows what he's doing, he's got some weapons," Leyland said. "He got a couple of balls up and paid the price for that but he's a good looking pitcher. I like him a lot."

Sanchez (5-8 overall) lost to Toronto for the second time this season; he gave up six runs in 3 1/3 innings of a 12-5 loss on June 22 while pitching for the Marlins.

Rasmus drove in Toronto's first run with a sacrifice fly in the third. Detroit tied it in the fourth when Young hit a two-out single and Boesch followed with a double to center, the only extra-base hit allowed by Alvarez.

The Blue Jays reclaimed the lead in the bottom half when Encarnacion led off with an opposite-field drive to right, his 28th.

"Encarnacion is hitting the ball out of the park almost every night it seems," Boesch said.

Escobar, who returned to the lineup after missing the past three games with a sore back, made it 3-1 with a leadoff homer to center on Sanchez's first pitch of in the sixth, his seventh.

"They were really aggressive on my first pitch," Sanchez said.

The Blue Jays chased Sanchez and padded their lead in the seventh. Rajai Davis doubled and stole third before Rasmus ended Sanchez's outing by hitting his 18th homer.
