National League

Giants 5, Cardinals 4

Rookie Kelby Tomlinson has been called upon out of necessity for the injury-plagued Giants, and he keeps delivering. Veteran Marlon Byrd has been called upon for big moments like this down the stretch, and is doing his part since coming to San Francisco this month in a trade from the Cincinnati.

Tomlinson lined a bases-loaded single up the middle with one out in the ninth against previously unbeaten Kevin Siegrist, and the Giants topped the Cardinals on Friday night to snap St. Louis' five-game winning streak.

"He just seems comfortable here," Giants manager Bruce Bochy said. "He's hit everywhere he's gone, Double-A, Triple-A and he's continuing to do that."

Left fielder Brandon Moss grabbed another glove from the dugout and moved in to make a five-man infield, then Tomlinson found a hole against Siegrist (5-1).

Byrd hit a grand slam off 15-game winner Michael Wacha in the third inning for the Giants, who kept pace 2 1-2 games behind NL West-leading Los Angeles.

Javier Lopez (1-0) got Moss to line out to second in the ninth and Tomlinson quickly fired to first to double up Stephen Piscotty, who was off the bag.

Byrd's eighth career grand slam gave the Giants eight for the season, a franchise record. Byrd last hit one on July 9, 2013, while with the Mets facing the Giants at AT&T Park.

"This one's a lot bigger," Byrd said. "It's a pennant race and the Dodgers already won. We needed this win tonight to stay on pace."

The scoreboard went out for about four minutes and the ballpark lights briefly flickered twice.

Byrd, previously 0 for 17 against Wacha, sent the first pitch he saw in the third over the wall in center field moments after Buster Posey was hit on the left elbow to load the bases against the team with baseball's best record.

"I've had a tough time against Wacha," Byrd said. "That's my only hit in my career, a lot of strikeouts. He's tough. I got one pitch to do something with and put a good swing on it."

Wacha surrendered an even more memorable shot more than 10 months ago.

Travis Ishikawa's improbable walkoff three-run homer clinched the NL pennant for the Giants with a 6-3 Game 5 win against the Cardinals in the NLCS at AT&T Park last October.

Mike Leake retired the first nine batters in order but is still missing his first win after three starts since joining the Giants in a trade from Cincinnati on July 30.

Josh Osich relieved Leake with runners on first and second and one out in the seventh, then retired pinch-hitter Jason Heyward and Matt Carpenter.

Cardinals rookie Piscotty, who played at Stanford and grew up in nearby Pleasanton, hit a two-run double in the fourth as St. Louis pulled back within 4-3. The right fielder robbed Matt Duffy in the sixth with a diving catch that took him over the bullpen mound.

"Let's not overlook, too, the fact we were down four in this game," Cardinals manager Mike Matheny said. "It was a great job of getting us back into this. Just couldn't get a whole lot going."

The Cardinals tied it on Leake's wild pitch in the top of the sixth.

St. Louis, which turned nine double plays in its recent four-game sweep at Arizona, committed two errors in the Giants' big third that made all four runs unearned.

Center fielder Gregor Blanco returned to the Giants' lineup after missing two games with a left hip strain.

Dodgers 4, Cubs 1

Clayton Kershaw struck out a season high-tying 14 to win for the first time in three outings and NL West-leading Los Angeles beat Chicago.

Kershaw (11-6) allowed one run and three hits in eight innings. He walked one in the Dodgers' first home game in two weeks.

Kenley Jansen pitched the ninth to earn his 26th save in 28 chances.

Jason Hammel (7-6) gave up three runs and four hits in five-plus innings.

Marlins 4, Nationals 3

Martin Prado and Marcell Ozuna homered off Max Scherzer, and Miami beat Washington.

The Nationals remained 6 1/2 games behind the Mets in the NL East.

Scherzer (11-11) went seven innings, allowing four runs and six hits. He has lost three straight starts for the first time since May 2010.

Adam Conley (2-1), in his fifth major league start, gave up three runs and six hits over five-plus innings.

A.J. Ramos pitched around a leadoff single in the ninth for his 23rd save.

Pirates 5, Rockies 3

Pinch-hitter Josh Harrison singled home Francisco Cervelli with the go-ahead run in the eighth inning and the Pittsburgh bullpen continued its hot streak in a win over Colorado.

Tony Watson (3-1) earned the win with a scoreless inning. Mark Melancon worked a perfect ninth for his major league-leading 42nd save. Pittsburgh relievers haven't lost a decision since June 25, strengthening their grip on the top NL wild-card spot.

Scott Oberg (3-3) took the loss.

Brewers 5, Reds 0

Taylor Jungmann pitched six strong innings and fellow rookie Domingo Santana homered to lead Milwaukee over Cincinnati.

Jungmann (8-5) limited the Reds to three hits and three walks while striking out five.

Rookie Raisel Iglesias (3-6) turned in a strong performance of his own by retiring 16 straight during one stretch.

Phillies 7, Padres 1

Rookie Aaron Nola pitched seven strong innings and Cameron Rupp homered and drove in four runs, leading Philadelphia past San Diego.

Rookie Aaron Altherr had an RBI triple as the Phillies ended their four-game losing streak. He has seven hits in the majors, all for extra bases.

Nola (5-1) allowed one run and two hits, striking out six.

Jerome Williams pitched two perfect innings to earn his first save. He was moved to the bullpen prior to the game to make way for righty Alec Asher.

Ian Kennedy (8-12) gave up two runs and two hits in 6 2-3 innings.

American League

Blue Jays 5, Tigers 3

Josh Donaldson and Troy Tulowitzki hit back-to-back homers, Jose Bautista also connected and Toronto won for the eighth time in 10 games, beating Detroit.

Ian Kinsler and Anthony Gose homered for the slumping Tigers, who have lost seven of eight.

R.A. Dickey (9-10) pitched 6 2-3 innings to win his sixth straight decision for the AL East leaders. Roberto Osuna struck out the side in the ninth for his 16th save.

All three Blue Jays homers came off rookie Matt Boyd (1-5), one of the three lefty pitchers acquired by Detroit in the July 30 trade that sent David Price to Toronto.

Rangers 4, Orioles 1

Cole Hamels delivered his best performance yet for Texas, striking out 10 in eight innings to beat Baltimore.

Star outfielder Adam Jones started for the Orioles, a day after he ran into a wall and was forced to leave, but Baltimore lost for the eighth time in nine games.

Hamels (2-1) gave up one run and two hits. Acquired from Philadelphia shortly before the July 31 non-waiver trade deadline, the three-time All-Star won for the first time at home after a pair of no-decisions.

Shawn Tolleson pitched a scoreless ninth inning for his 27th save in 29 chances. Texas held its lead for the second AL wild-card spot.

Kevin Gausman (2-6) has made 11 starts this season, beginning in late June, with one win.

Twins 3, Astros 0

Eduardo Nunez homered and Kyle Gibson pitched 5 2-3 scoreless innings to help Minnesota top AL West-leading Houston.

Royals 3, Rays 2

Kendrys Morales hit his 15th homer, Edinson Volquez pitched into the seventh inning and AL Central-leading Kansas City beat Tampa Bay.

Volquez (12-7) allowed two runs and six hits in 6 2-3 innings. Greg Holland, the third Kansas City reliever, got three outs for his 29th save.

Indians 3, Angels 1

Trevor Bauer, starting in place of an ill Danny Salazar, allowed one run in eight innings and Cleveland defeated the Los Angeles Angels.

Bauer (10-10) won for the second time in nine starts. He replaced Salazar, who was scratched because of a virus. Bauer allowed five hits and struck out seven.

Cody Allen worked a perfect ninth for his 27th save.

Jason Kipnis, the American League's leading hitter (.324), drove in the go-ahead run with a seventh-inning single to cap a three-run rally. Kipnis, who had struck out twice and hit into a double play in his first three at-bats, delivered off Trevor Gott (2-2).

Mariners 2, White Sox 0

Kyle Seager and Franklin Gutierrez both had three hits and a homer and Taijuan Walker allowed three hits before leaving with an injury in the seventh inning as Seattle beat the Chicago White Sox.
