PHILADELPHIA — Kyle Schwarber hit four home runs in one game last month that put the Philadelphia Phillies slugger on the precipice of 50 home runs this season.

Then he waited. And waited some more.

Schwarber’s home run drought — as much as the designated hitter could really have one this year — spanned 10 games and 49 plate appearances as he chased the milestone.

Schwarber reached 50 home runs in a season for the first time when he hit a three-run shot off reliever Justin Hagenman in the seventh inning of a 9-3 victory over the New York Mets.

“I don’t know what to say about why have you hit so many homers or whatever it is,” Schwarber said. “It’s just the way it happens. It’s not like I go up there trying to do that. It just finds its way. It’s a cool thing.”

Schwarber joined 2008 World Series champion Ryan Howard as the only Phillies players to reach 50 home runs in a season. Howard hit 58 in 2006.

Schwarber is the first player in big league history with a four-homer game and 50 home runs in the same season. His power stalled after he became the 21st major leaguer and fourth Phillies player to hit four homers in a game on Aug. 28 against Atlanta.

“I went through a little bit of a rough patch,” Schwarber said. “I felt like over the last four or five days, I was having some really good, quality at-bats. Hitting some balls hard. There’s not anything you can do to worry about that.”

Schwarber’s home run hit just under the pitch clock in straightaway center field and gave the Phillies a 7-1 lead as he became the first National League player to reach 50 this season. Seattle Mariners catcher Cal Raleigh leads the majors with 53 home runs.

NATONALS 7, MARLINS 5 Josh Bell homered for the fourth time in three games, Mitchell Parker threw 7 2/3 innings of two-run ball and visiting Washington beat Miami. Parker (8-15) retired 14 consecutive batters after allowing Joey Wiemer’s solo home run in the second. The left-hander allowed 4 hits, struck out 2 and walked 2. Rookie Daylen Lile also went deep while CJ Abrams and James Wood doubled and singled each for the Nationals.

CUBS 6, BRAVES 1 Rookie Cade Horton threw 6 1/3 strong innings, Pete Crow-Armstrong drove in two runs and Chicago pulled away from host Atlanta. Horton (10-4), a leading candidate for National League Rookie of the Year, allowed one run on four hits with no walks. Crow-Armstrong went 1 for 2, walked, was hit by a pitch and had two steals.

INTERLEAGUE

ORIOLES 3, PIRATES 2 (11) Samuel Basallo hit an RBI single in the 11th inning that was initially ruled a foul ball to give host Baltimore a victory over Pittsburgh. Basallo’s popup to left grazed off the glove of left fielder Tommy Pham, landed on the chalk in the outfield grass, and was ruled foul. After a review, it was ruled a hit to drive in Gunnar Henderson for the Orioles’ third consecutive walk-off victory.

RANGERS 5, BREWERS 4 Michael Helman’s two-run home run in the bottom of the fifth inning tied the game at 3-3, which Wyatt Langford broke with and RBI triple to center field later in the inning, as host Texas held off Milwaukee. Langord scored on Kyle Higashioka’s double to give Texas a 5-3 lead. Jake Bauers hit a solo home run — his seventh of the season — to center field in the ninth for Milwaukee. Christian Yelich had an RBI single and William Contreras added a two-run double for the Brewers.

AMERICAN LEAGUE

GUARDIANS 2, ROYALS 0 Joey Cantillo allowed four hits in a career-best eight-plus innings, José Ramírez homered, doubled and scored twice, and host Cleveland beat Kansas City for its fifth consecutive victory. Cantillo (5-3) struck out five and didn’t issue a walk. Ramírez, who had three hits, hit a solo home run off Royals starter Noah Cameron (7-6) with two outs in the first. David Fry hit the second of back-to-back to doubles to drive in Ramírez in the fourth. Cameron (University of Central Arkansas) gave up 2 runs on 6 hits with 8 strikeouts in 7 innings.

TIGERS 12, YANKEES 2 Parker Meadows hit a go-ahead single to spark a nine-run seventh inning and Kerry Carpenter added a two-run triple as visiting Detroit took advantage of wild relievers Fernando Cruz and Mark Leiter Jr. in a victory over New York. Detroit sent 14 batters to the plate in the seventh and the first nine reached against Cruz (2-4) and Leiter, who combined to allow four walks, four hits and a hit batsman.

BLUE JAYS 4, ASTROS 3 (10) Tyler Heineman drove in the winning run in the 10th inning and host Toronto rallied to defeat Houston. Vladimir Guerrero Jr. reached on an infield single against Craig Kimbrel (0-1) to begin the 10th, advancing automatic runner Myles Straw to third base. Daulton Varsho struck out and Heineman followed with a fielder’s choice grounder to first base, where a diving Christian Walker couldn’t throw home in time to retire the speedy Straw.

RAYS 5, WHITE SOX 4 Tristan Gray, Josh Lowe and Richie Palacios homered to help visiting Tampa Bay outlast Chicago. Gray hit a tiebreaking solo drive off Tyler Alexander (5-14) in the seventh inning. It was Gray’s third home run in 17 games since he was acquired in a July 26 trade with the White Sox for cash. Tampa Bay earned its 11th win in 16 games.
