Brandon Morrow brought his ‘A’ game.

For the most part, the Houston Astros were overmatched.

End of story.

It was the second start of the season for Morrow, his first one against the Tampa Bay Rays last week a bit on the dull side as, in that contest, he allowed four runs on seven hits over five innings. Pedestrian for Morrow.

On this night, however, Morrow was first class through five of his six innings in pitching the Jays to a 7-3 victory, which marked their first series triumph of the season and leaves them — and, yes, we know it’s early — in first place in the AL East with a 5-4 record. They go for the sweep Thursday night with R.A. Dickey on the mound.

In the first inning, Morrow struck out the side on 15 pitches, topping out a few times at 97 mph. That’s bringing it.

Throughout the spring, there were questions concerning Morrow’s velocity, or lack of it. Back then, he was throwing 91-93, but claiming all was well and that, if he needed to step on the gas, he had plenty in the tank.

On Wednesday night, he put the pedal down early and stayed there, blowing it by the Astros and then freezing them by dropping in a breaking ball.

“He was throwing the crap out of the ball. He was throwing downhill, using all of his pitches really good,” catcher Dioner Navarro said. “He gave us a real shot to win the game.”

It was never a contest, never in doubt ,after the Jays opened a 5-0 lead.

“Very good, very good,” manager John Gibbons said of his right-hander. “In the sixth inning, they ambushed him a little bit but, overall, he was dominating, pumping it pretty good.”

Over the opening three innings it was nine up, nine down with Morrow striking out six.
