BALTIMORE -- Blake Davis' rookie debut was memorable, but for all the wrong reasons.
The second baseman, playing in place of the injured Brian Roberts, allowed a two-out ground ball to skip through his legs against the Pirates on June 22, and two runs scored on the error. Those runs would prove to be the difference, as the Pirates took a lead they never relinquished.
But since then Davis has grown more comfortable at second, and he made a diving catch in the top of the sixth inning on Wednesday night, robbing Cardinals first baseman -- and Baltimore native -- Mark Hamilton of a base hit.
"I'm just getting a little bit more comfortable," Davis said of his web gem. "That was just a reaction play."
Davis, who is 5-for-16 with two RBIs and a stolen base in five appearances, has moved past the costly error he made in Pittsburgh. He was a shortstop in the Orioles' Minor League system from 2006 to 2010, and his first experience at second base came in a game last season for Double-A Bowie.
"It's in the past, you put it behind you," he said. "Errors are going to happen. It's not like you're out there trying to let that happen to you. But you bounce back, forget about it and just try to do the best you can."
Since Roberts sustained a head injury on May 16, the Orioles have struggled to find a consistent backup at second. They have experimented with Davis, whose contract was selected from Triple-A Norfolk on June 18; Robert Andino, who got the start on Thursday night; and Ryan Adams, who played nine games until being sent down to make room for Davis.
The Orioles will likely continue to platoon Davis and Andino in place of their franchise second baseman, who will not return before the All-Star break and has an unclear timeline even beyond that.
Showalter to lend efforts to KidsPeace
BALTIMORE -- Manager Buck Showalter and his wife, Angela, pledged their support on Thursday to KidsPeace, a 129-year-old national children's charity organization.
With offices in Maryland, Virginia and the District of Columbia, KidsPeace provides foster care and community services to hundreds of people, ranging in age from 3 to 21, who have mental and behavioral health issues.
As part of their support, both Showalters will be featured in a public service announcement for KidsPeace, and Angela has agreed to serve as a volunteer member of the KidsPeace Board of Associates for Maryland. In addition, the couple has agreed to serve as honorary chairmen for the KidsPeace Annual 5K Race & Fun Walk, to take place in Baltimore on Oct. 29.
On Thursday, left fielder Nolan Reimold got his first start in six games dating back to June 19. In 20 games this season, he was batting .261, but he hit just .111 in his last 10 games.
Designated hitter Vladimir Guerrero will likely sit during the three-game series in Atlanta unless there's an injury.
Jake Arrieta, whose start was pushed back to Saturday from Wednesday, felt good in his side session on Wednesday and is ready to pitch against the Braves.
Manager Buck Showalter thinks Luke Scott has improved since bruising his knee making a leaping catch on Tuesday night. Scott was available to pinch-hit on Wednesday and Thursday.
