Even Jose Bautista is surprised with how many home runs he's piling up.

Bautista hit two more homers, increasing his major league leading total to 18, Yunel Escobar added a tiebreaking shot and the Toronto Blue Jays rallied to beat the Houston Astros 7-5 on Saturday.

Baseball's reigning home run king had 54 last season, more than tripling his previous career high of 16. He's on pace to not just beat that mark this year, but smash it.

''It's always a surprise when you keep hitting home runs,'' Bautista said. ''I'm not surprised about the RBIs or the fact that I'm playing well. Given what happened last year, knowing what I feel like I'm capable of doing, I expected to perform at a high level. I'm doing probably a little bit better than I expected.''

Rookie teammate Eric Thames is just as shocked by Bautista's unbridled power.

''Man, this guy's a freak.'' Thames said. ''You think you can just hold him down, but he makes adjustments. He just smashes the ball.''

Bautista hit a three-run drive to left off Brett Myers in the sixth and added a solo shot to left against Jose Valdez in the eighth. It was his third multihomer game of the season and the 14th of his career.

In the seventh, after Jose Molina tied it at 4 with a two-out single to center, Escobar hit a two-run drive to left, his fourth.

Escobar's shot also came off Myers (1-4), who has not won since April 12, a span of seven starts. The right-hander allowed six runs, five earned, in 6 2-3 innings. He walked none and struck out two.

''I made some good pitches, but also a couple of mistakes and they hit them hard,'' Myers said. ''Sometimes you get away with them, but I haven't all year. It's been tough.''

Casey Janssen (1-0) pitched one inning for the win.

After Jason Frasor worked a perfect eighth, the Blue Jays needed two pitchers to close it out in the ninth. Jon Rauch was replaced after giving up an RBI double to Angel Sanchez. Former Astros closer Octavio Dotel came on and struck out Hunter Pence, then got Carlos Lee to ground out to earn his first save.

The Astros jumped on Blue Jays right-hander Brandon Morrow with two runs in the first. Michael Bourn drew a leadoff walk, Pence hit a one-out single and Houston loaded the bases when Lee reached on a fielder's choice, with Pence beating third baseman John McDonald's throw to second. Brett Wallace drove in the first run with a sacrifice fly and Johnson followed with an RBI single to right, but Lee was thrown out trying to advance to third.

Johnson hit an RBI single in the third and added a sacrifice fly in the fifth as the Astros built a 4-0 lead.

Morrow allowed four runs and nine hits in six-plus innings. He walked three and struck out six.

The Blue Jays struggled to get anything going through the first five innings against Myers, who set down 10 in a row after Bautista's infield single in the first.

Toronto put runners at first and second after a pair of singles in the fifth, but McDonald lined into an inning-ending double play, with Juan Rivera caught off second base.

Defensive lapses cost the Astros as Toronto rallied in the sixth and seventh. Molina opened the sixth with a single and Escobar reached on a fielding error by shortstop Clint Barmes. One out later, Bautista blasted an 0-1 pitch to left, cutting the deficit to one.

''We've made mistakes a lot of times this year that have hurt us and I made a really big one today,'' Barmes said. ''It's pretty frustrating, that's for sure, especially with what our records reads and how it's gone this year.''

Bautista had been struggling to catch up with Myers's fastball, but homered on a hanging curve.

''I know when he has runners on base he throws a lot of offspeed,'' Bautista said. ''Sometimes sliders, sometimes curveballs and sometimes a changeup, but I know his favorite pitch is a curveball. I wasn't sitting on it, but I was looking for something slower.''

In the seventh, Blue Jays rookie Eric Thames reached on a ground-rule double when left fielder Brian Bogusevic failed to come up with Thames's fly ball into the gap.

''I had it,'' Bogusevic said. ''At the last second, I froze up. I caught a glimpse of (center fielder Michael Bourn) as he was backing me up. I caught a glimpse of him out of the corner of my eye and I froze on it. I should have caught it.''

One out later, Thames scored the tying run on Molina's groundball single, and Escobar followed with his tiebreaking homer.
