John Lannan pitched a seven-hit shutout Tuesday, pacing the Washington Nationals to a 4-0 victory over the New York Mets. Lannan (7-7), who walked none, had his first-ever shutout and his second complete game of the season. Adam Dunn was 2-for-4 with an RBI and a run scored for the Nationals, who won for the first time in six games under new Manager Jim Riggleman, who replaced Manny Acta during the All-Star break.

The Washington Nationals, who entered baseball's All-Star break with the worst record in the major leagues, Monday fired Manager Manny Acta. Acta was in his third season as the Washington manager. He amassed a record 158-252.

Washington Nationals left-hander Scott Olsen was placed on the 15-day disabled list Sunday because of shoulder tendinitis. The ailment flared up when he hurled five innings Saturday against the Philadelphia Phillies. On the team's Web site, Manager Manny Acta said after the contest that Olsen had hurt his left shoulder and was still bothered by the left ankle problems he suffered last Sunday against the Arizona Diamondbacks. The doctor gave him a shot, Acta said.
