Nationals 2, Cubs 1

WASHINGTON — Ross Detwiler allowed four hits in seven shutout innings and Adam LaRoche homered 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 in 2011.

The Nationals' win allowed them to hold their 6 1/2-game division lead over Atlanta.

Detwiler (9-6) struck out three and walked three, and allowed a runner to third only once.

Jeff Samardzija (8-13) gave up a long home run to LaRoche to lead off the second. LaRoche's 25th home run landed in the front row of the second deck. It's the fourth time in his career LaRoche has hit 25 or more home runs.

Ryan Zimmerman's RBI double scored Bryce Harper in the eighth for the second run.

Drew Storen pitched a perfect eighth.

Cardinals 5, Mets 4

ST. LOUIS - Rookie Joe Kelly pitched 6 2-3 effective innings and also doubled, helping the St. Louis Cardinals defeat the New York Mets 5-4.

Kelly (5-6) allowed five hits and two runs. He made his second start after a brief stint in the bullpen, and turned in his longest outing of the season.

Edward Mujica got the last out of the seventh, giving him 16 straight scoreless appearances since coming over from Miami at the trade deadline. Jason Motte recorded five outs for his 33rd save in 38 chances.

Skip Schumaker hit a solo homer and Matt Carpenter drove in two runs for the NL wild card-leading Cardinals.

Daniel Murphy and Kelly Shoppach hit two-run homers for New York, which had won three straight and seven of eight.

Astros 5, Pirates 1

PITTSBURGH — Brett Wallace had three hits, including a three-run homer, to lift the Houston Astros past the Pittsburgh Pirates 5-1 on Monday.

Edgar Gonzalez (1-0) picked up his first victory as a starter in more than four years, giving up a run on five hits in 5 1-3 innings as the Astros won for just the third time since interim manager Tony DeFrancesco took over two weeks ago. Gonzalez struck out five and walked just one.

Jeff Locke (0-1) ran into trouble early and never recovered as the Pirates dropped their fourth straight. Locke surrendered five runs in five innings to remain winless in five big league starts.

Garrett Jones had three hits for the Pirates, who failed to come through at the start of an important six-game homestand that could determine whether they stay in the National League wild card race.

Marlins 7, Brewers 3

MIAMI — Jose Reyes drove in three runs and the Miami Marlins snapped a four-game losing streak with a 7-3 victory against the Milwaukee Brewers on Monday.

Ricky Nolasco (11-12) gave up three runs, though only one was earned, and nine hits in seven innings. He was coming off his third career shutout, against Washington.

Mike Fiers (8-7) lasted 3 1-3 innings. He gave up six runs (four earned), six hits, walked four and struck out four.

Steve Cishek relieved Mike Dunn with runners on first and second and two out in the ninth. Cishek retired Ryan Braun on a chopper to second for his 12th save in 16 chances.

Phillies 4, Reds 2

CINCINNATI, Ohio — Jimmy Rollins hit a three-run homer off Johnny Cueto during a cloudburst that sent fans scurrying for cover on Monday afternoon, leading the Philadelphia Phillies to a 4-2 victory over the Cincinnati Reds.

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'd been 11-0 in 13 afternoon starts.

Rollins' 17th homer made it 3-1 in the fifth inning, when Cueto had trouble with the muddy mound. It was Rollins' 1,999th career hit.

Rookie right-hander Tyler Cloyd (1-1) got his first major league hit and win. He gave up four hits, including Jay Bruce's 30th homer, and struck out nine in seven innings.

Braves 6, Rockies 1

ATLANTA - Kris Medlen struck out a career high 12 to lead the Atlanta Braves to a 6-1 win over the Colorado Rockies on Monday.

Medlen (7-1) allowed five hits without a walk in his second complete game of the season.

He extended his streak of scoreless innings to 34 2-3 — the Braves' longest since Greg Maddux in 2000 — before the Rockies scored an unearned run in the seventh.

The right-hander, who appeared in 38 games in relief before moving into the rotation on July 31, improved to 6-0 with a 0.54 ERA in seven starts. He spent most of 2011 on the disabled list recovering from elbow ligament-replacement surgery on Aug. 18. 2010.

Giants 9, Diamondbacks 8

SAN FRANCISCO — Marco Scutaro hit an RBI single in the 10th inning after Buster Posey's tying double in the ninth, and the San Francisco Giants rallied to beat the Arizona Diamondbacks 9-8 on Monday.

Brandon Crawford beat out a single to short leading off the final inning and moved to second when Brett Pill dropped his first career sacrifice bunt. Angel Pagan grounded out to first to advance Crawford to third.

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.

Putz had converted 19 consecutive saves until blowing a chance against the Dodgers on Sunday.

Sergio Romo (4-2) pitched a perfect 10th for the Giants.

Dodgers 4, Padres 3 (11)

LOS ANGELES — A.J. Ellis singled in the winning run in the bottom of the 11th inning, giving the Los Angeles Dodgers a 4-3 victory over the San Diego Padres on Monday night for their second consecutive walk-off win.

Ellis got the game-ending hit off Cory Burns (0-1) after two-out singles by Andre Ethier and Luis Cruz, who had a career-high four hits.

Ethier tied the game 3-all with his 16th homer off Luke Gregerson with one out in the bottom of the ninth.

Brandon League (1-1) got the win with two innings of relief. He gave up one hit, struck out two and walked one.
