Flande set to be Rockies' 12th starting pitcher

DENVER -- Yohan Flande will put the number of starters the Rockies have used this season at an even dozen, and the season isn't even at the halfway point.

Flande, a left-hander who has been in pro baseball since 2005, will be summoned from Triple-A Colorado Springs to make his Major League debut. He'll replace the injured Christian Bergman, who made his debut three starts ago but is out with a broken bone in his left hand.

Twelve starters used is good for the Major League lead.

To put into perspective how far the Rockies have dug into their depth chart, consider that manager Walt Weiss has seen Flande about as much as he's seen the Cardinals pitcher who is making his own debut on Wednesday, 2014 first-round Draft choice Marco Gonzales.

Flande made five Spring Training appearances for the Rockies with strong numbers -- one run allowed on six hits in six innings.

"He only made a few outings for us, but there's some deception," Weiss said. "He's a bit of a left-handed slinger, and he has shown the ability to get ground balls. That's what I remember about him."

The times Weiss saw Gonzales, in 2010, were more memorable because of the high school stakes involved.

"I've probably seen him pitch a couple of times," Weiss said. "And when I was an assistant over at Regis Jesuit, we played Marco's team, Rocky Mountain [High, Ft. Collins, Colo.], in the final four. His dad [Frank, now the Rockies' coach at short-season Tri-City] was his coach. Marco didn't pitch that game, but I think he hit a three-run homer against us."

Weiss also is considering having his entire battery making a Major League debut -- something that is more likely to happen during the expanded-roster days of September than in the middle of the year. Catcher Jackson Williams, who began his pro career in 2007 with the Giants but was stuck behind Buster Posey and others, is with the club through Wednesday while Michael McKenry is on bereavement leave. Weiss said he was considering having Williams catch Flande.

The Rockies went into Tuesday night with seven players having made Major League debuts this season -- starting pitchers Bergman, Eddie Butler and Tyler Matzek, all of whom debuted in a six-day period, plus relievers Tommy Kahnle and Chris Martin, and first baseman/outfielder Kyle Parker.
