Ross Detwiler allowed four hits in seven shutout innings and Adam LaRoche homered on Monday, giving the Washington Nationals their first winning season with a 2-1 victory over the Chicago Cubs.
The NL East-leading Nationals improved to 82-52. The club moved from Montreal to Washington for the 2005 season and went 81-81 that year. In 2008 and 2009, the team lost a combined 205 games, then finished 80-81 last year.
Detwiler (9-6) struck out three and walked three, allowing only one runner to reach third.
Jeff Samardzija (8-13) gave up a long home run to LaRoche to lead off the second.
Tyler Clippard allowed two hits and a two-out RBI single to Welington Castillo in the ninth. Clippard threw the ball away for an error and allowed pinch-runner Tony Campana to advance to second before striking out Josh Vitters for his 30th save in 33 opportunities.
PHILLIES 4, REDS 2
In Cincinnatti, Jimmy Rollins hit a three-run homer off Johnny Cueto during a cloudburst that sent fans scurrying for cover, leading Philadelphia over Cincinnati.
John Mayberry Jr added a solo homer off Cueto (17-7), who failed in his attempt to become the majors’ first 18-game winner. Cueto also lost a day game for the first time this season — he had been 11-0 in 13 afternoon starts.
Rookie right-hander Tyler Cloyd (1-1) got his first major league hit and win. He singled ahead of Rollins’ homer to extend the inning. The 25-year-old gave up four hits, including Jay Bruce’s 30th homer, and struck out nine in seven innings.

Scutaro sent the final fastball from Bryan Shaw (1-5) past diving third baseman Chris Johnson for San Francisco’s seventh walk-off win. Scutaro also doubled and scored the tying run in the ninth to help hand J.J. Putz his second straight blown save.

Jeff Locke (0-1) ran into trouble early and never recovered as the Pirates dropped their fourth straight in the race for the NL’s second wild-card spot. Locke surrendered five runs in five innings to remain winless in five big league starts.
