ARLINGTON -- Tigers manager Jim Leyland said "it's good and bad" that the bullpen has had such a strong start to the season.

Detroit relievers entered Friday's game with a combined 5-2 record and a 2.47 ERA in 54 2/3 innings. That's the good news. The bad news is the 'pen is going better than three innings per game.

In Thursday's 5-4 victory over the Angels, starter Justin Verlander needed 125 pitches to get through five innings. That forced the bullpen into four innings of work. Ryan Perry, Phil Coke, Joel Zumaya and Jose Valverde did a magnificent job holding the lead, but it's the long haul that concerns Leyland.

"We're not going to be able to use the bullpen the way we have been all season long," Leyland said. "Somebody is going to get hurt."

Leyland is so troubled by the overuse of the bullpen that he brought the subject up on his own Friday after fielding several other questions on various topics.

"What's going on is going to spell disaster for the bullpen," Leyland said. "Someone [a starting pitcher] is going to have to step up and give you quality innings."

Guillen officially placed on DL

ARLINGTON -- Tigers outfielder Carlos Guillen was hobbling around the visitor's clubhouse at Rangers Ballpark on Friday after being placed on the 15-day disabled list with a left hamstring strain.

"It's sore," Guillen said.

Guillen had been swinging a hot bat of late, batting .333 in his past 10 games with a home run and six RBIs. Top prospect Brennan Boesch was called up from Triple-A Toledo to replace him.

"Guillen had started hitting the ball well," manager Jim Leyland said. "It's a crying shame."

Boesch doubled in the first at-bat of his Major League debut.

Texas homecoming for Tigers' Jackson

ARLINGTON -- Tigers rookie center fielder Austin Jackson will be playing before family and friends all weekend. He played his high school baseball at nearby Denton Ryan High School, which is 20 miles north of Arlington.

"It's going to be fun playing in front of a bunch of family and friends who haven't gotten to see me play," Jackson said. "They'll be getting to see me play for the first time."

Jackson said he has several relatives coming from Oklahoma for Saturday's game. His former high school coach and several former teammates will also be coming to see him play.

"It's cool that he put that together," Jackson said.

Worth noting

The Tigers arrived at their team hotel at 6:45 a.m. CT on Friday after playing a night game in Anaheim. It won't be the first time on this road trip. Detroit and Texas play a night game Monday, so the Tigers will get into Detroit late Tuesday morning and have to turn around that night for a showdown with the AL Central-leading Minnesota Twins. Manager Jim Leyland said he knows it's part of the game, but still, he doesn't like it. "It's ridiculous, but it's part of it," he said. ...
