Verlander was 11-17 with a 4.84 ERA last season. He also had been shaky this spring, yielding four runs and three hits over two innings in his previous start last Wednesday against the New York Yankees. He walked four in that game, including three straight hitters in the second.

This one went a lot better for the Tigers ace.

"I am not someone who is ever going to lose his confidence," Verlander said. "Everything I do is about progressing every day. Yes, it was a big stride forward, but I never lost my confidence."

Verlander threw 68 pitches against Houston and said he had enough left for at least another inning but realized the rest of the staff also needed some work. The Tigers are off Wednesday and manager Jim Leyland is running out of time to figure out his bullpen situation.

"I am not concerned about Verlander," Leyland said. "(Tuesday) he had the best curveball I've seen from him including last year. He mixed his pitches and when he does that he is an outstanding major league pitcher."

Astros starter Brian Moehler made his fourth start of the spring and allowed four hits in five scoreless innings.

"I felt better the last two innings than I did the first three," Moehler said. "It was just a matter of locating better. I just thought I was a little all over the place the first couple of innings. I felt much better the last two."

Geoff Blum drove in Houston's run in the fourth and Scott Sizemore tied it with a home run in the eighth.

"I'm upset about my hitting. We have got to figure out a way to hit at spring training," said Astros manager Cecil Cooper, whose team is 1-14. "We've got to figure out a way to get it done. This is just absolutely pathetic and I don't care if it's veterans, rookies, whatever it is. Forty-one years and I've never seen it like this. I've been around a long time and I've never, ever seen it. Something's got to give, sooner rather than later."

Notes: Most of the Tigers, including the coaching staff, are off Wednesday, but they will play two intrasquad games using mostly minor leaguers. Edwin Jackson will start the morning game and Nate Robertson, who is in a fight for the last rotation spot, will start the afternoon game. ... Leyland said he is following the World Baseball Classic and wants to get his players back as soon as possible. His entire starting outfield along with starting pitcher Armando Galarraga are playing in the WBC and he said he's disappointed that Carlos Guillen has been playing mostly designated hitter for Venezuela. Guillen is moving from first base to the outfield for the Tigers this season and Leyland hoped that would be Guillen's spot during the WBC. "I don't want to stick my nose into it but I can't do anything about it," Leyland said.
