Mookie Betts went 2 for 4 with a homer and three RBIs in a dazzling return from the injured list that sparked the Los Angeles Dodgers to a key 5-2 win over the Milwaukee Brewers on Monday.

In his first game since fracturing his left hand on June 16, Betts hit a two-run homer that broke a scoreless tie in the third inning and later added a run-scoring single to lead Los Angeles in the opener of this four-game series between National League division leaders.

Shohei Ohtani also had a two-run homer, his NL-leading 36th of the season, to help Clayton Kershaw earn his first win since September in the three-time Cy Young Award winner's best start of the season.

Kershaw (1-2) held the Brewers to one run and three hits through 5 2/3 innings in his fourth start since returning from offseason shoulder surgery.

The Dodgers have now won four straight and moved a half-game ahead of the East-leading Philadelphia Phillies in the race for the NL's best record. Milwaukee dropped to 2 1/2 games behind Los Angeles and has lost two in a row following a five-game winning streak.

Betts stepped to the plate with Teoscar Hernandez aboard in the third inning and drove a 2-1 pitch from Milwaukee starter Freddy Peralta over the left field wall to stake Kershaw to a 2-0 lead. 

Ohtani made it 4-0 two innings later by following a Kevin Kiermaier single with an opposite-field homer off Peralta (7-7), who was tagged for four runs on five hits in six innings.

Kershaw departed with two out and a runner on in the sixth in favour of Joe Kelly, who was greeted by a home run by William Contreras that brought the Brewers within 4-2.

Betts struck again in the seventh, however, with a two-out single that plated Ohtani, who drew a walk and advanced to second with his 33rd stolen base of the season.

Three Dodger relievers then combined to keep the Brewers scoreless over the final three innings, with Daniel Hudson working a perfect ninth to notch his ninth save. 

Valdez stars again as Astros win sixth straight

Framber Valdez and the Houston Astros both extended their unbeaten runs as the American League West leaders opened a three-game series with the Tampa Bay Rays with a 6-1 victory.

Valdez (12-5), who lost a no-hit bid with two outs in the ninth inning in his previous outing, struck out nine while yielding just one run and three hits over 5 2/3 innings to improve to 7-0 with a 2.68 ERA over his last nine starts. The Astros have won all of those appearances.

Yainer Diaz supplied the big blow in Houston's sixth consecutive win with a three-run homer in the third inning. Alex Bregman added a solo shot to help the Astros move a half-game ahead of the Seattle Mariners for sole possession of the AL West lead.

Bregman's blast off Taj Bradley in the first inning put Houston ahead quickly, and the Astros broke the game open with four runs in the third.

After Bradley walked Chas McCormick and gave up a single to Jose Altuve, Yordan Alvarez drove in McCormick with a two-out hit to increase the margin. Diaz then belted the first pitch he saw into the left field seats for a 5-0 advantage.

The Rays got on the board in the bottom of the third when Taylor Walls tripled and scored on Jose Caballero's sacrifice fly, but managed just two hits off Valdez and two Houston relievers the rest of the way en route to their fifth loss in seven games.

Houston tacked on one more run in the fifth as Alvarez doubled, advanced to third on Jeremy Pena's infield single and scored on a fielder's choice groundout off the bat of Jake Meyers.

Bradley (6-7) lost his third straight start after allowing six runs and eight hits over 4 1/3 innings.

Braves score in 10th to win duel of aces with Giants

Travis d'Arnaud drove in the game's lone run with a sacrifice fly in the 10th inning as the Atlanta Braves earned a needed 1-0 win over the San Francisco Giants in the opener of a four-game series.

The game featured a matchup of standout pitchers that lived up to its advanced billing, as both Atlanta's Chris Sale and the Giants' Blake Snell turned in dominant performances despite neither factoring in the final outcome.

Sale racked up a season-high 12 strikeouts while permitting just three hits over seven scoreless innings, while the reigning NL Cy Young Award winner Snell fanned 11 Braves and surrendered two hits in 6 1/3 shutout innings.

The Braves finally broke the deadlock with Orlando Arcia placed as the designated runner to start the 10th. Sean Murphy then singled off Taylor Rogers to move the go-ahead run to third before d'Arnaud's fly ball to right was deep enough to enable Arcia to score.

Raisel Iglesias was able to strand the Giants' designated runner in the bottom of the inning by recording two strikeouts before getting Patrick Bailey to fly out and end the game. The Atlanta closer also pitched a scoreless ninth to keep the contest at 0-0.

The lack of run support prevented Sale from becoming the majors' first 14-game winner this season, though his outstanding effort helped the Braves increase their lead over the rival New York Mets to one game for the NL's final wild card spot.

Atlanta entered the series having gone 7-14 over its previous 21 games to fall out of the top spot in the wild-card race.

The Giants have now dropped two straight following a 12-3 stretch that got them back into the play-off picture. San Francisco is now 2 1/2 games behind Atlanta in the standings.

Shohei Ohtani had a career-high three doubles and the Los Angeles Dodgers collected 20 hits in an 11-2 rout of the Washington Nationals on Wednesday.

Ohtani went 3 for 6 with RBI doubles in the eighth and ninth innings. He leads the majors in batting average (.371), slugging (.695), OPS (1.128), extra-base hits (21) and doubles (14).

Mookie Betts and Will Smith each had four hits and rookie Andy Pages homered as the Dodgers won their third straight following a three-game skid.

Landon Knack earned his first win in his second career start, allowing two runs and three hits in six innings. He retired his last 13 batters and struck out five.

Nick Senzel homered for the Nationals, who didn’t have a baserunner after the second inning.

Trout hits MLB-leading 10th home run in loss

Mike Trout became the first player in the majors to reach 10 home runs this season, but Gunnar Henderson had three hits and three RBIs as the Baltimore Orioles held off the Los Angeles Angels, 6-5.

Trout got the Angels on the board with a solo shot off starter Dean Kremer in the sixth inning. This is the third time in the past seven seasons that Trout has been the first in MLB to reach double digits in homers.

Los Angeles rallied back from a 6-0 deficit and had the tying run on first in the ninth, but Jo Adell was caught stealing to end the game.

Henderson homered for the second straight game and added a two-run single in Baltimore’s four-run sixth. He is 9 for 20 in the past five games and 18 for 40 with five home runs and 11 RBIs in his last 10 games, helping the Orioles win eight.

Kremer struck out 10 over 5 2/3 innings and allowed two runs and three hits for his first win of the season.

Surging Braves win in 10 innings

Michael Harris II doubled home Ronald Acuna Jr. in the 10th inning and the red-hot Atlanta Braves topped the Miami Marlins, 4-3, after blowing a two-run lead in the ninth.

The Marlins scored twice in the ninth off Braves closer Raisel Iglesias to tie it but failed to score in the top of the 10th.

Harris led off the bottom half with a single to center to score the winning run and send Atlanta to its ninth win in 10 games.

Harris went 3 for 5 and Marcell Ozuna had three hits and two RBIs, giving him an MLB-best 29.

The Marlins were swept for the third time this season and dropped to an NL-worst 6-20.
