Towers, Gibson to discuss club's roster

DETROIT -- D-backs manager Kirk Gibson will sit down with general manager Kevin Towers when the team returns home on Sunday night to discuss the team's roster.

Towers has recently been watching the club's Double-A and Triple-A teams.

Injured reliever Sam Demel made his second rehab appearance for Triple-A Reno on Saturday night and could be close to returning.

"KT's been out and about and I think he's got some thoughts on his mind," Gibson said. "He's been to Mobile and Reno. We'll see what he wants to do."

Whether that means roster moves are on the horizon or not remains to be seen. While Demel may return soon, it sounds like he will make at least one more Minor League appearance.

"He's thrown two games in Reno and he's been off for over a month, so does that mean he's at full speed?" Gibson said. "I mean he's pitched in a couple of games, but is he ready to get used three out of four days? Probably not. I'd rather him get back at full speed, be strong and be fully prepared to do what we have to do with no limitations. We want to confirm that he's in fact strong and ready to go."

Putz pays a visit to University of Michigan

DETROIT -- To say that D-backs closer J.J. Putz is a fan of the University of Michigan would be to understate his allegiance.

"It's fair to say that our family bleeds maize and blue," said Putz, who pitched for the Wolverines from 1996-99. "I have tremendous pride in the university.

Putz paid a visit to the campus on Saturday afternoon and received a tour of Schembechler Hall -- the football facility that bears the name of the legendary former Michigan coach -- from assistant athletic director Kurt Gulbrand.

Included in the tour was a surprise sitdown in the office of first-year head coach Brady Hoke.

  • 131 wins
  • 121 wins
"The more I listen to him, see him on TV talking and meet him in person, the more I'm convinced that he's the right person to lead the university," Putz said. "Not just the football team, but the university."

While on campus, Putz dined at Pizza House and loaded up on some Michigan logo attire for the family. Mostly, though, it was a chance to relive some of the best times of his life.

"It changed my life," Putz said of his decision to attend Michigan. "Going there was the best decision I ever made. I had a chance to sign out of high school and turned down a decent amount of money to go there. I ended up meeting my wife and made lifelong friends."

Pena likely to sit as team returns home

DETROIT -- What to do with Wily Mo?

That's the question facing the D-backs in their upcoming three-game series with the Indians which begins Monday night at Chase Field.

The D-backs called up Wily Mo Pena from Triple-A Reno last Tuesday for a stretch of games in which they would play six of nine in American League parks, and therefore need a designated hitter.

Pena has come as advertised, showing prodigious power with two homers in his first four games, but also a lot of strikeouts. Defense is not his strength, so he figures to be on the bench for the next three games against the Indians.

D-backs manager Kirk Gibson said prior to Sunday's game that he had not thought ahead to his lineups for the Cleveland series, but it didn't sound like Pena would be in them.

"I don't know if I can see him in the outfield," Gibson said. "Right now he's pretty much going to be the designated hitter for us. He's certainly imposing and dangerous."

Following the brief three-game homestand, the D-backs will play their final three Interleague games against the A's in Oakland from July 1-3.

Worth noting

• Outfielder Justin Upton doubled over after reaching first base in the first inning on Sunday, and Tigers first baseman Miguel Cabrera waved for the Arizona training staff to come out onto the field. "I just felt sick," Upton said. "When I got in the box the first time I felt nauseous, and then when I got to first I thought I was going to throw up. I took some Alka-Seltzer between innings and I was fine. I feel fine now."

• Third baseman Melvin Mora was scratched from the starting lineup just prior to the game with soreness in his back. He will be examined when the team returns home.

• D-backs manager Kirk Gibson and bench coach Alan Trammell received a prolonged standing ovation when they were introduced to the crowd during the pregame ceremony to retire former Tigers manager Sparky Anderson's No. 11.

"Embarrassing," said Gibson, a Detroit legend. "I'm shy about stuff like that. I didn't expect it. There's a fondness obviously with Tram and I in Detroit. We spent a ton of time here. We accomplished a lot and went through a lot of hardships together. It just shows you that people don't forget. It was very humbling. I was like, 'Get that camera off of me. This is for Sparky.'"
