With their success against Houston this season, the Tigers may be wondering why the Astros didn't move to the American League sooner.

Prior to this season, the Tigers were 6-9 all-time against Houston but they are enjoying a dominant stretch, winning the first five, including a four-game sweep in Houston two weeks ago.

On Tuesday night, the offense didn't get going until the fifth inning but provided enough run support for starter Doug Fister, as the Tigers rolled to a 6-2 victory at Comerica Park.

After Tuesday's win, the Tigers may be looking for a way to get the Astros in the Central Division to play even more games.

Miguel Cabrera went 2-for-3 with a double and a home run — his eighth of the season — and Fister (5-1) went seven innings and allowed two runs on five hits and notched seven strikeouts.

"We know that the offense is pretty good and excel at what they do. but that doesn't change my mind set," said Fister, who threw 108 pitches. "Every inning, it's 0-0 and I have to go out there and put up zeros."

Fister gave up both runs in the 35-pitch second inning after back-to-back singles by Chris Carter and Carlos Pena. J.D. Martinez had an RBI single and Jimmy Paredes added a sacrifice fly. But Fister settled down, allowing just two singles to the next 19 batters — and retiring 12 straight between the third and seventh innings.

"One thing about most of our pitchers is they've learned not to get too excited when things don't go just right and to settle in," manager Jim Leyland said. "A lot of that is the fact that they're mature. The other thing is they know we have an offense that can come back.

"It keeps them relaxed a little bit. It's not like if they give up a run or two, the game's over. They know if they can keep the damage to a minimum, we have a chance to come back."

The Tigers hitters were stymied in the first four innings, managing just one hit off Astros starter Lucas Harrell (3-4). But they broke it open in the fifth with two outs, as Omar Infante singled to left and stole second. Don Kelly followed with an RBI single and Ramon Santiago added an RBI double.

"One thing I liked about tonight is Don Kelly got the big RBI to give us the first run; Santiago got a big RBI to tie it up," Leyland said. "That kind of stuff really makes me happy because those guys don't really get to play that much and they contributed. Miggy hit the bomb and Doug settled in."
