Notes: Medders trying to look past stats

Right-hander leads the league in home runs allowed

DENVER -- Brandon Medders' stat line tells a story of a pitcher struggling on the mound.

He's pitched 16 2/3 innings and has allowed a whopping eight home runs. That's 4.3 homers for every nine innings pitched, by far the highest total in the big leagues.

The numbers only tell part of the story, though. To get the rest of it you have to look in his eyes. They tell the human side of the story -- a pitcher struggling to deal with adversity.

"I take it personally," he said. "This is embarrassing for me to pitch like this. To walk in the clubhouse and have everybody know that I'm the one guy down in the bullpen not getting the job done."

Arizona manager Bob Melvin recently shifted Medders into more of a middle innings role, rather than the seventh-inning setup role he had been in, to try and give him a mental break while he tries to figure out why seemingly every mistake he makes winds up getting hit over the wall.

"The way I look at it I'm not making the pitches I need to make," Medders said. "I blame everything on myself. The way I wish it was, that I was not getting away with any mistakes. But I can't make any excuses. I take it hard because I feel like it's my fault. If I made every pitch the way I wanted to I would be OK. I just have to concentrate pitch by pitch."

Tracy to DL: Third baseman Chad Tracy left Tuesday night's game in the seventh inning with recurring pain in his left ribcage and seems headed for the disabled list.

"It looks like that is what's going to be best for it," Tracy said. "It just gets worse and worse during the game. It's just to the point where I can't backhand a ball down the line and throw across. My third at-bat it felt like someone was stabbing me in my side."

Tracy originally suffered the injury May 1 in Los Angeles and it kept him out of the lineup for a week. After he returned, he continued to feel discomfort, and it's continued to get worse.

With Alberto Callaspo on the restricted list and Minor League infielders Augie Ojeda and Brian Barden out with injuries, the club could decide to call up highly-regarded prospect Mark Reynolds from Double-A Mobile.

Reynolds was hitting .306 with six homers and 22 RBIs for the BayBears.

Options: With infielder Alberto Callaspo still on the restricted list and Minor League infielders Augie Ojeda and Brian Barden both injured, the D-backs are thin in the infield, particularly at shortstop.

"We've spent time on that and looked at a few options, and we'll continue to look at it and assess it each day," D-backs GM Josh Byrnes said.

Byrnes will join the team in Denver on Wednesday.

Back in there: Micah Owings will go back into the starting rotation on Saturday in Pittsburgh.

With two off days in a week's span, the club decided to have Owings skip one turn. The right-hander was available if needed out of the bullpen Tuesday and will throw as normal between starts in a bullpen session Wednesday.

Keeping the faith: Right fielder Carlos Quentin entered Tuesday's game hitting just .195.

"He's pressing like a lot of our guys are," Melvin said. "You don't see the results that you expect to see and it's your first time in the big league level for a long period of time, you just press. Confidence kind of creeps in there, but he's not the only guy who's had to go through it. He'll get through it. You need a bloop hit here, a two or three-hit game there, and now you're back on track. Sometimes that's all it takes."

Familiar face: The Rockies on Sunday acquired former D-backs reliever Jorge Julio from the Marlins in exchange for another former Arizona player, Byung-Hyun Kim.

The D-backs had traded Julio to the Marlins just before the end of Spring Training.

"I am happy to face these guys," Julio said of the D-backs. "When they trade you, you want to do your best against them. And I know these guys, all their hitters. ... I know how to pitch these guys. I am ready. [It'll be a] good team for me to face."

Up next: The D-backs and Rockies continue their series Wednesday night with reigning NL Cy Young Award winner Brandon Webb taking on Aaron Cook.
