PHOENIX (AP) — Rookie Wade Miley pitched eight innings to earn his 14th victory, and Arizona beat Miami 3-0 on Wednesday night to complete a sweep of the first home doubleheader in Diamondbacks history.

Fellow left-hander Tyler Skaggs (1- 0) made his major league debut in the opener, allowing two runs and three hits over 6.2 innings in a 3-2 victory.

Miley (14-8) gave up four singles, struck out five and walked one.

Paul Goldschmidt singled in a run in the first, then doubled and scored in the fourth for Arizona. Aaron Hill had a two-run homer and RBI single in the first game.

Miami’s Wade LeBlanc (2-3) gave up three runs, two earned, and five hits in seven innings in the nightcap.

J.J. Putz pitched a scoreless ninth in both games for his 16th and 17th consecutive saves. He has 26 saves in 29 tries on the year.

Brewers 3, Cubs 2

MILWAUKEE (AP) — Ryan Braun hit his NL-leading 34th homer and Yovani Gallardo pitched seven strong innings as Milwaukee completed a three-game sweep of Chicago.

John Axford pitched a scoreless ninth to convert his second straight save, returning to his role as the Brewers’ closer after he was demoted earlier in the season.

Gallardo (13-8) gave up two runs and four hits, with nine strikeouts and two walks.

Braun hit a solo shot deep to rightcenter in the sixth and had an RBI double in the first. With Wednesday’s homer, Braun has surpassed the 33 he hit during his 2011 NL MVP season.

Braves 5, Nationals 1

WASHINGTON (AP) — Kris Medlen pitched seven shutout innings in his latest winning performance and Martin Prado’s two-run double proved decisive to help the Braves end a fourgame losing streak.

Medlen (5-1) allowed seven hits while striking out seven and walking one in his fifth start of the season. The Braves have won 16 consecutive starts behind the right-hander dating to May 2010.

Atlanta salvaged the three-game divisional series and halted the Nationals’ three-game winning streak.

Reds 3, Phillies 2

PHILADELPHIA (AP) — Bronson Arroyo allowed three hits in eightplus innings, and Jay Bruce homered to lead Cincinnati.

Arroyo (10-7), who gave up both runs while striking out four and walking none, retired the first 14 batters before Domonic Brown’s two-out homer in the fifth. Brown doubled off the wall in right-center with one out in the eighth and pinch-hitter Kevin Fransden reached on an infield single leading off the ninth for the other hits off Arroyo.

Arroyo, who was 0-6 with a 9.46 ERA in his last seven regular-season starts against the Phillies, improved to 6-1 with a 3.50 ERA in his last seven starts.

Rockies 5, Mets 2

NEW YORK (AP) — Wilin Rosario hit a tiebreaking homer in the seventh inning, and Colorado won its seventh straight victory at Citi Field.

Rosario also had a sacrifice fly, and DJ LeMahieu drove in a run with a squeeze bunt to help the last-place Rockies win their fourth straight and eighth in 11 games. Colorado will go for a four-game sweep on Thursday, a feat the Rockies accomplished during their previous visit to Queens in April 2011.

Cardinals 4, Astros 2

ST. LOUIS (AP) — Kyle Lohse pitched seven innings of three-hit ball to earn his seventh consecutive win for St. Louis.

Lohse (13-2) gave up two runs and retired his last 14 batters while improving to 7-0 with a 2.21 ERA in 12 starts since he dropped a 3-2 decision against Kansas City on June 15.

The Cardinals have won consecutive games to grab a half-game lead on Pittsburgh for the second wild-card spot in the National League.

Padres 4, Pirates 2

SAN DIEGO (AP) — Andrew Werner allowed two runs over six-plus innings in his major league debut and Carlos Quentin drove in three runs for San Diego.

The Padres swept the three-game series and have beaten the Pirates in 18 of 21 games.

Quentin had three RBIs for the second straight game, including a tworun double in the first inning and an RBI single in the fifth.

Giants 8, Dodgers 4

LOS ANGELES (AP) — Matt Cain pitched seven strong innings and Joaquin Arias homered and drove in a career-high five runs as San Francisco completed its first three-game sweep at Dodger Stadium in five years.

The Giants arrived in Los Angeles trailing the Dodgers by a half-game and they leave with their largest lead in a month. The Dodgers last got swept at home by the Giants April 24-26, 2007.

The Giants avenged a three-game sweep by the Dodgers in San Francisco last month that created a virtual tie atop the division.
