Rockies place Tulo on DL with hip flexor strain

DENVER -- Tuesday was supposed to be the day Rockies shortstop Troy Tulowitzki finally tested out his left thigh after resting the injury the past two games. Instead, it ended up being the day he landed on the disabled list for the first time in the 2014 season.

The Rockies placed Tulowitzki on the DL Tuesday with a left hip flexor strain. The move is retroactive to July 20, one day after he departed Saturday's 3-2 loss to the Pirates with left thigh cramp.

The Rockies needed a roster spot for Tuesday's starter Yohan Flande, but manager Walt Weiss said that didn't play much into their decision. Josh Rutledge has started the past two games in Tulowtizki's absence and he's expected to get "the lion's share" of playing time moving forward, according to Weiss.

"If Tulo was going to be ready tomorrow or the next day, we still would have held him out," Weiss said. "But we didn't feel like that was [the case]."

Tulowitzki hasn't played 150 games in a season since 2009, missing time with an assortment of injuries. Leg muscle injuries have been the primary culprit over the years and Tulowitzki believes most of his troubles stem from a left quadriceps tendon tear in 2008.

"It's always going to be battle for me with my injury history," Tulowitzki said. "Starting with the quad tear in [2008], it's really been an uphill battle from then because all the muscles have to work that much harder ... I didn't know to the extent, but here we are six years later and it's still giving me issues."

Tulowitzki chalked this injury up to just "a little bump in the road." He and Weiss both confirmed, too, that it was a combination of him needing rest and the Rockies needing a full bench.

In years past, Tulowitzki might have shown more frustration with his body failing him yet again. But he's been exceptionally healthy this season, playing in 91 of the Rockies 99 games entering Tuesday.

That's largely because of a virtually non-stop, extensive maintenance program he's implemented to keep his body ready. And it's his commitment to that regimen that offers solace in his current situation.

"I understand how hard I've worked," Tulowitzki said. "I've said all along, if something were to happen this year, it's a lot easier for me to take because I do everything I possibly can to prepare myself every day [and] in the offseason to get ready to play. … There's no regrets and that's nice."

Tulowitzki was putting up MVP-caliber numbers before the injury, leading the Majors in average (.340), on-base percentage (.432) and one-base plus slugging (1.035) all while playing Gold Glove worthy defense.

The four-time All-Star expects to pick up right where he left off as soon as he's healthy.

"One thing I don't lack is confidence," Tulowitzki said. "When I'm back, I'll be a confident player out there. To be a confident player out there, you have to be confident in your body, so I have to be healthy before I come back. Especially with where we're at, there's no need to rush it."
