BALTIMORE -- Catcher Jesus Flores has been getting the job done for the Nationals. He is hitting .367 with one home run and seven RBIs. By being so productive, manager Manny Acta put Flores in the sixth spot of the lineup on Saturday against the Orioles.

"He has been tremendous for us. He has had quality at-bats in almost every outing that he has had," Acta said.

Flores went 0-for-2 and ended up being ejected by home-plate umpire Tim McClelland in the sixth inning. Flores' back was turned when McClelland made his decision.

"I'm really surprised," Flores said. "I just asked, 'Where was that pitch?' He just threw me out of the game. There was nothing I could do about it. It was the third time I asked him, but I wasn't mad."

McClelland wasn't available for comment, but Acta felt the ejection was uncalled for.

"Flores is a kid who has impeccable conduct, not only with me, but the coaches, players and every one around the league," Acta said. "I don't know what happened there."

Pitching matchup
WAS: LHP John Lannan (3-4, 3.74 ERA)
Lannan pitched six innings and gave up four runs on 12 hits against the Mets in his last start. He had problems with left-handed hitters and the bottom of the order. The batters in the eighth and ninth spots went 4-for-5, while left-handed hitters were 5-for-9. Lannan's biggest problem was a former member of the Nationals, Ryan Church, who had four RBIs, including a solo home run.

BAL: RHP Jeremy Guthrie (2-3, 4.18 ERA)
The Orioles shuffled their rotation to keep Guthrie on turn, a maneuver made necessary by three days off during a seven-day span. Baltimore elected to skip Steve Trachsel, who likely will slot back into the rotation in the middle of next week.
