Francisco Alvarez's solo home run in the bottom of the ninth inning lifted the New York Mets to a dramatic 4-3 win over the Baltimore Orioles in Monday's opener of an important three-game series for both teams.

With one out and the game tied at 3-3, Alvarez crushed a 3-0 fastball from Seranthony Dominguez well clear of the wall in left center field to allow the Mets to close the gap in the National League wild card race and knock the Orioles out of first place in the American League East.

J.D. Martinez had a two-run homer in the first inning for New York, which moved within 1 1/2 games of the Atlanta Braves for the NL's final wild card spot with its third win in four games.

The Orioles have now lost three of four and dropped a half-game back of the idle New York Yankees for the AL's top spot.

Baltimore made it interesting, however, by scoring twice in the seventh inning to erase a 3-1 deficit.

Ryan Mountcastle began the rally with a lead-off double and took third on a groundout before being forced home when Mets starter David Peterson was called for a balk. Ramon Urias then followed with a solo home run to knot the score at 3-3.

Peterson had been cruising up until that point and departed after allowing three runs - two earned - while striking out eight through seven innings.

Martinez followed a first-inning single by Mark Vientos with his 13th homer of the season to give the Mets an early advantage. They increased the margin to 3-0 in the fourth when Pete Alonso doubled and later crossed the plate on Tyrone Taylor's two-out single.

The Orioles answered in the fifth with the help of an error by Peterson, who threw errantly on a pickoff attempt to send Urias to third after the infielder reached on a double. Urias would then score on a groundout by Jackson Holliday.

Urias and Mountcastle each finished with two hits for the Orioles, while Baltimore starter Trevor Rogers struck out five while permitting three runs in 4 2/3 innings.

Diaz's homer in ninth caps rally, keeps Astros hot

The Houston Astros also earned a key win via a walk-off home run, as Yainer Diaz's ninth-inning blast gave the AL West leaders a 5-4 comeback victory over the Boston Red Sox.

Houston scored once in each of the final two innings to rally for its 11th win in 12 games, with Diaz delivering the final blow by launching Kenley Jansen's pitch well over the left field wall with one out in the bottom of the ninth.

The Astros tied the game at 4-4 with a two-out rally an inning earlier, as Chas McCormick singled off reliever Lucas Sims and stole second before racing home on Mauricio Dubon's clutch single.

Yordan Alvarez and Victor Caratini each collected three hits to help Houston increase its lead over the second-place Seattle Mariners to five games in the division.

The slumping Red Sox lost for the eighth time in 12 games despite taking a 4-2 lead on Masataka Yoshida's pinch-hit two-run homer off reliever Tayler Scott in the top of the sixth inning. Romy Gonzalez was aboard for the blast after reaching on an error by Houston second baseman Jose Altuve, one of a season-high four miscues for the Astros.

Houston got closer in its half of the sixth, however. Back-to-back singles by Jeremy Pena and Caratini put runners on first and third for Jon Singleton, who drove in Pena with a sacrifice fly to trim the lead to 4-3. 

Astros starter Yusei Kikuchi struck out seven over 5 2/3 innings while allowing three runs, one earned, though his night began ominously when Boston's Jarren Duran connected on his 16th homer of the season on the game's first pitch.

Rob Refsnyder and Rafael Devers each singled later in the first inning before another Houston error - a misplay by rookie third baseman Shay Whitcomb - enabled another run to score.

The Astros were held scoreless by Tanner Houck through the first three innings before breaking through in the bottom of the fourth, which Alvarez began with a double and Diaz followed with a single. Alvarez was later thrown out at home on a fielder's choice grounder, but Caratini singled in Diaz and Pena also scored on the play on an errant throw by Boston catcher Danny Jansen.

Houck worked six innings and struck out eight while surrendering three runs - two earned.

Stone, Muncy propel Dodgers over Mariners in Turner's Los Angeles return

Gavin Stone racked up a career-high 10 strikeouts in seven innings, Max Muncy homered in his first game back from the injured list, and the Los Angeles Dodgers spoiled Justin Tuner's return to Dodger Stadium with a 3-0 win over the Seattle Mariners.

Muncy, sidelined since May 16 by a right oblique strain, came through with a two-run homer in the seventh inning to back Stone's superb start and help the Dodgers win the opener of this three-game series between playoff hopefuls.

Gavin Lux homered earlier in the seventh to break a scoreless deadlock and a terrific pitching duel between Stone and Bryan Woo, who had allowed just one hit until Lux drove a pitch over the wall in center field.

Woo (5-2) then hit Will Smith with a pitch and was removed in favour of Yimi Garcia, who was greeted by Muncy's towering drive to right that quickly made the lead 3-0.

Stone (11-5) yielded just two hits and two walks before departing, with Joe Kelly pitching a scoreless eighth before Evan Phillips retired the side in order in the ninth to notch his 16th save.

Woo was charged with two runs in 6 1/3 innings in slumping Seattle's sixth loss in seven games. The defeat dropped the Mariners five games back of first-place Houston in the AL West.

Turner went 1 for 3 in his first appearance at Dodger Stadium in nearly two years. The 39-year-old infielder made two NL All-Star teams during a successful nine-year tenure with the Dodgers from 2014-22. 

Shohei Ohtani hit a leadoff homer for the second straight game and extended his RBI streak to a franchise-record 10 consecutive games in the Los Angeles Dodgers’ 4-0 win over the lowly Chicago White Sox on Wednesday night.

Ohtani took Erick Fedde deep on a full-count fastball for his National League-best 25th home run. It was his third leadoff homer of the season and his eighth home run in the last 10 games.

He is batting .310 (27 for 87) with 11 homers and 23 RBIs in 23 games this month.

Gavin Stone shut down the White Sox on four hits in his first career complete game. He struck out seven and walked none to improve to 8-1 with a 2.03 ERA in his last 11 starts.

Los Angeles (51-31) won its fourth straight and has won eight of 10 to move a season-best 20 games over .500.

The major league-worst White Sox (21-61) have lost seven of eight to fall 40 games under .500. They were shut out for the 12th time this season and were 1 for 21 with runners in scoring position while totalling three runs and 17 hits in the three-game series.

Streaking Astros roll Rockies

Spencer Arrighetti struck out a season-high 10 over seven scoreless innings and was backed by Yainer Diaz’s three hits as the Houston Astros won their season-high seventh straight, 7-1 over the Colorado Rockies.

Arrighetti limited the Rockies to three hits and didn’t walk a batter for the first time in the longest start of his rookie season.

Houston (40-40), which opened 7-19, reached .500 for the first time this season and is batting .320 while averaging 6.9 runs during the seven-game streak.

The Astros broke open the game with a four-run seventh to take a 6-0 lead. Cesar Salazar had a sacrifice fly before Jose Altuve hit a soft grounder to shortstop Ezequiel Tovar and his throw home was high, allowing another run to score.

Alex Bregman then grounded into a forceout, but a throwing error by second baseman Brendan Rogers sent another run home. Yordan Alvarez hit a ground-rule double and Diaz’s single stretched the lead to 6-0.

The Rockies are 0-4 against the Astros this season and have dropped 11 in a row at Minute Maid Park, dating to Aug. 15, 2018.

Orioles end skid, cool Guardians

Cedric Mullins snapped a tie with a seventh-inning home run and Gunnar Henderson belted his 26th of the season as the Baltimore Orioles snapped the Cleveland Guardians’ seven-game winning streak with a 4-2 victory.

Ryan O’Hearn also went deep for the Orioles, who had lost five in a row since a 17-5 pounding of the Yankees on June 20. It was their longest losing streak since May 2022.

Mullins connected off Xzavion Curry to lead off the seventh, putting Baltimore ahead 3-2.

Grayson Rodriguez surrendered solo home runs to Jhonkensy Noel and Gabriel Arias but not much else. He gave up three other hits over seven innings without a walk and struck out four.

Cionel Perez pitched a perfect eighth and Craig Kimbrel struck out the side in the ninth for his 17th save and 434th of his career.

Noel was recalled from Triple-A Columbus and became the fourth Cleveland player to homer in his first major league at-bat. The last Cleveland player to go deep in his first at-bat in the majors was Kevin Kouzmanoff in 2006.

The Los Angeles Dodgers got sterling pitching performances from Tyler Glasnow and Gavin Stone as they swept a double-header against the New York Mets on Tuesday and snapped a five-game losing streak.

In the opener, the Dodgers rallied late, and Freddie Freeman hit a two-run homer off Jorge Lopez in the 10th inning for a 5-2 win.

The Dodgers trailed 2-0 most of the game until Freeman’s single in the eighth inning drove in Andy Pages. Teoscar Hernandez scored the tying run in the ninth after a well-placed Chris Taylor bunt.

Glasnow gave up a home run to Francisco Lindor in the third but pitched seven innings, allowing two hits and two runs with eight strikeouts.

Mets starter Tylor Megill pitched seven scoreless innings, allowing three hits with nine strikeouts.

In the nightcap, Stone pitched a gem to improve to 5-2 after allowing three hits in seven scoreless innings.

Will Smith and Miguel Vargas backed Stone with solo home runs. Freeman added two more hits to finish the double-header 5 for 8.

Seager powers Rangers in World Series rematch

Corey Seager hit his seventh home run in as many games, Nathan Eovaldi returned from injury and the Texas Rangers beat the Arizona Diamondbacks 4-2 in a rematch of last year’s World Series.

Seager, the 2023 World Series MVP, hit a three-run blast off Brandon Pfaadt in the fifth inning to continue his tear. After a slow start to the season, Seager extended his hitting streak to 11 games, with a .480 on-base percentage in that span.

Eovaldi made his first start in nearly four weeks after being sidelined with a right groin strain. Instead of making a minor-league rehab start this week, Eovaldi pitched three innings against Arizona on Tuesday, allowing five hits and two runs.

Andrew Heaney, Grant Anderson, David Robertson and Kirby Yates pitched six scoreless out of the Texas bullpen to close the game.

The Rangers have won back-to-back games after a 2-12 slump.

Cubs lose no-hit bid, beat Brewers in extras

The Chicago Cubs carried a no-hitter into the eighth inning, then had an offensive explosion in extras to beat the Milwaukee Brewers 6-3 and snap a five-game losing streak.  

Rookie right-hander Ben Brown was pulled after seven hitless innings, allowing two walks and striking out 10 in 93 pitches.

Milwaukee’s Sal Frelick singled off Hayden Wesneski with one out in the eighth to break up the no-hit bid.

The Cubs held a 1-0 lead much of the night, thanks to a third-inning home run by Michael Busch, but the Brewers tied it with two outs in the ninth on a Willy Adames single that plated Christian Yelich.

Chicago responded with a five-run 10th inning, highlighted by Ian Happ’s two-run double off Hoby Milner.
