"I would say everybody at this point is hard for us to replace," said manager Dave Trembley of losing his primary shortstop. "But I would say any time your shortstop is down, that's a key part of your defense. We're confident that Andino can step in and do a nice job for us, but that's a key guy for us to lose."
Izturis, who signed with the Orioles as a free agent last winter, was brought in to repair the team's shortcomings at shortstop. And while he hasn't hit much, Izturis has proven to be a capable defender in the season's first six weeks. Now, the Orioles have to figure out a way to live without him for the next few days.
"He's better then we thought, he's improved," said Trembley. "I got a good report from [head athletic trainer Richie Bancells] yesterday. We'll see how he is tomorrow. I'd say for now, he's day-to-day."
Izturis, who's batting .243 with a .281 on-base percentage this season, said he injured himself in a collision with Royals pitcher Ron Mahay during Sunday's game. The switch-hitter said he doesn't expect to be sidelined too long, and he said that he has already noticed some improvement in the past couple days.
"Today was a little better," Izturis said. "Yesterday, it was sore in the morning. We had to put ice on it, and heat, but it was still bothering me a little bit. Today, I'll get treatment and see how it is tomorrow.
"The pain's gone away, so it's a good sign. Just a couple days, it will be fine. It's not getting any worse."
Baltimore targeted Izturis after trying to identify a starting shortstop for virtually all of last season. The Orioles went through four starters -- Luis Hernandez, Freddie Bynum, Alex Cintron and Juan Castro -- at the position last year. Izturis has started 33 of the team's first 38 games, with Andino starting the remainder.
