KANSAS CITY -- Left-hander Dana Eveland emerged as an unsung hero on Wednesday in the Orioles' 15-inning win over the Royals.

Eveland delivered three scoreless innings from the 10th through the 12th innings and showed signs that his background as a starter could bode well for him when long relief is needed.

"He's not a pure lefty-on-lefty guy," O's manager Buck Showalter said. "Starting [left-handed] pitchers have to learn how to defend themselves against right-handed hitters. He was a big difference in that game. We didn't have to use [Luis] Ayala, and we were able to stay away from [Pedro] Strop, which we were trying to do."

Eveland's three innings tied for the long relief outing by a Baltimore pitcher this season. He allowed just one hit, a dribbler down the third-base line by Alex Gordon.

Jones' skills could earn return trip to KC

KANSAS CITY -- The Orioles won't come back to Kauffman Stadium this season, barring a Baltimore-Kansas City playoff series. But the notion of center fielder Adam Jones making another appearance at Kauffman -- site of the 2012 All-Star Game -- is gaining credibility by the day.

Jones came up big again on Wednesday with a game-winning homer in the 15th inning to lift the Orioles past the Royals, 4-3. He added a two-run homer on Thursday to help the Orioles overcome an early 3-0 deficit in a 5-3 win.

After Wednesday's game, Jones was asked about the possibility of returning to Kansas City for the Midsummer Classic.

"That's not up to me," Jones said. "If I keep doing what I'm doing, you never know."

O's manager Buck Showalter knows that Jones has played like an All-Star through the opening six weeks of the season. When Jones connected for a 431-foot blast against Royals reliever Nate Adcock, he became the first player since Mark McGwire in 1988 to hit a home in the 15th inning or later in multiple games in the same season. Jones homered in the 17th inning on May 6 in Boston.

"Jonesy respects competition," Showalter said. "If somebody makes him look bad, he's not going to become a wallflower. He's going to compete regardless of how the game is going. He's still trying to control his emotions and he's getting a lot better about that. Not getting himself out. Not many people get him out in the strike zone. He wants to do something for our club so bad every time he comes to the plate. If he gets to the point where he'll take a base on balls with the bases loaded, we're on our way."

Wieters earns break after marathon duty

KANSAS CITY -- Orioles manager Buck Showalter had a preliminary plan to pencil in Matt Wieters as his starting catcher on Thursday. But the plan changed after Wieters worked 15 innings in a 4-3 win over the Royals on Wednesday night.

That marathon game meant Luis Exposito drew a start behind the plate in the series finale at Kauffman Stadium.

"We were thinking about doubling [Wieters] up if we had a short game," Showalter said. "I looked at J.R. (bench coach John Russell) in the 11th inning and said 'I guess that idea about Wieters isn't happening.'"

Wieters played in 35 of Baltimore's first 38 games.
