Dodgers 3, Diamondbacks 1

Walker Buehler's second time on the mound against the Arizona Diamondbacks this season went far better than the first.

Buehler held the Diamondbacks to a run on two hits in eight innings, matching the longest start of his career, and Corey Seager hit a three-run homer as the Los Angeles Dodgers beat the Diamondbacks on Monday.

The NL West-leading Dodgers won their sixth straight, improving to 42-19. The Diamondbacks saw their two-game winning streak halted.

Buehler (6-1) lasted just three innings at Dodger Stadium on March 31 against Arizona but carried a no-hitter into the bottom of the fifth Monday and got the first two outs before Christian Walker homered. Buehler struck out a season-high 11 without a walk for his first career win over the Diamondbacks.

"The efficiency is the biggest thing for me," the 24-year-old right-hander said. "I think I'm going to strike guys out in this league and I've kind of shown that. To get deeper into games is obviously my goal."

Seager hit a full-count pitch from Arizona starter Robbie Ray (4-3) out to left-center field in the top of the fourth to break a scoreless tie. Justin Turner singled and David Freese walked with one out ahead of Seager's eighth homer of the season.

Going into Monday's game, Seager was 3 for 26 in his career against Ray.

"He's a tough matchup," Seager said. "Kind of tried a bunch of different things and didn't have success against it, and still trying to figure out how to grind out some at-bats against him. He's good."

Walker almost had his second hit with one out in the eighth, but Chris Taylor reached up and caught his line drive in deep center field. Buehler struck out Carson Kelly to end the eighth and walked to the visitors' dugout to a standing ovation from Dodgers fans seated along the first-base side.

"Wasn't stressed at all, because he was just so efficient in his delivery," Dodgers manager Dave Roberts said. "But honestly it was the fastball on both sides of the plate that was just dominant and missing bats all night long."

Arizona failed to provide enough run support for Ray, who gave up three runs on six hits in seven innings and struck out nine.

"It felt like my command was as good as it has been all year," Ray said. "I was pounding the zone, keeping them off balance with my off-speed, honestly just one bad pitch."

Kenley Jansen worked the ninth inning for his 18th save in 20 chances. Arizona brought the tying run to the plate with two outs, but David Peralta popped out to end the game.

Peralta, the Diamondbacks' leading hitter this season, returned to the lineup for the first time since May 21. He missed 11 games with a sprained right shoulder.

Peralta made an early impact defensively. He fielded Alex Verdugo's two-out single to left field and one-hopped a throw home to get Freese trying to score from second base. Diamondbacks catcher Kelly applied the sweep tag on Freese's arm to end the top of the second.

Turner was in the starting lineup for the first time since May 29 and had two hits. He missed the next three games with hamstring tightness before drawing a walk on Sunday in his lone plate appearance.

"Buehler in L.A. was still coming back from a short spring training and wasn't at full strength, and you could see what he is capable of doing," Diamondbacks manager Torey Lovullo said. "It was pretty impressive."

The Diamondbacks made left-handed hitting outfielder Corbin Carroll out of Seattle's Lakeside High School their first pick in Monday's draft. Carroll was the 16th overall selection.

The Diamondbacks and Dodgers each had two first-round picks. Los Angeles chose Tulane third baseman Kody Hoese with the 25th overall pick. Arizona took high school left-hander Blake Walstson at No. 26, and the Dodgers chose North Carolina second baseman Michael Busch at No. 31.

Padres 8, Phillies 2

Manny Machado hit a grand slam over Bryce Harper in the first showdown this season between the superstars who changed teams during spring training and San Diego beat NL East-leading Philadelphia.

It was Machado's 10th homer this season and first since May 14.

Machado's two-out slam off JD Hammer highlighted the seven-run sixth. After rookie Josh Naylor hit a two-run single to knock out Aaron Nola (6-1), Hammer came on and walked Greg Garcia to load the bases. He struck out Franmil Reyes before Machado drove the next pitch over Harper's head and into the home run deck in right field.

Franmil Reyes homered in the fifth, his 17th, and Ian Kinsler hit a go-ahead double in the sixth.

Nola allowed six runs and eight hits in 5 1/3 innings, struck out three and walked three.

San Diego's Eric Lauer (5-4) held the Phillies to one run and two hits in six innings, struck out three and walked three.

J.T. Realmuto homered in the seventh, his ninth. He also had an RBI single in the fourth.

Astros 4, Mariners 2

Robinson Chirinos homered to cap a three-run first inning, Houston added an insurance run on a baffling play by Seattle's defense, and the Astros won for the sixth time in seven games.

Chirinos' eighth home run capped a first inning in which Seattle's decision to use Cory Gearrin as an opener backfired. Gearrin (0-2) gave up an RBI triple to Josh Reddick, a run scoring groundout to Yuli Gurriel and Chirinos' long homer to cap his one inning of work before handing off to Wade LeBlanc.

Houston tacked on another run in the sixth when Seattle's defensive problems resurfaced.

Seattle got solo home runs from Mallex Smith and Edwin Encarnacion in the third inning, but the Mariners were 0 for 8 with runners in scoring position.

Houston starter Corbin Martin was pulled after just three innings, but relievers Framber Valez (2-2) and Chris Devenski worked five scoreless innings. Ryan Pressly pitched the ninth for his third save.

Cubs 8, Angels 1

Jon Lester allowed one run in seven innings, and Chicago beat Los Angeles in the makeup of a contest scheduled for April 14 that was postponed because of inclement weather.

Coming off three straight losses at St. Louis in which they scored six total runs, the Cubs broke loose with a five-run sixth inning. Javier Báez began the onslaught with a run-scoring double, one of his three RBIs, as Chicago picked up its second win in its past eight games.

Lester (4-4) allowed four singles, walked one and struck out six, giving up his only run on a sacrifice fly by Jonathan Lucroy in the seventh.

Former Cub Trevor Cahill (2-6) was charged with five runs on six hits and two walks in 4 1/3 innings in relief of opener Cam Bedrosian. Cahill has one win in his last nine appearances.

Báez and Willson Contreras homered off Luís Garcia in the seventh.
