NEW YORK — Francisco Álvarez hit a go-ahead, two-run double in the sixth inning and the New York Mets beat Atlanta 5-3 to split a doubleheader Monday after Braves star Ronald Acuña Jr. exited the nightcap early with a bruised shoulder.

Sean Murphy had a pair of three-run homers in the opener, powering the Braves to a 9-8 victory after the teams were rained out the previous two days.

In the first game, Acuña launched a 448-foot home run into the rarely reached third deck at Citi Field and finished a triple shy of the cycle. Leading off the second game, he was drilled in the left shoulder with a 93 mph fastball from Tylor Megill on an 0-2 count.

Acuña sat on the ground for a while holding his shoulder in obvious pain while receiving attention from an athletic trainer. He walked back to the dugout and was replaced by pinch-runner Kevin Pillar.

Initial X-rays were negative, but Acuña was undergoing more testing at a hospital before joining the Braves for their trip to Miami.

The win was just the second in eight games for the Mets, who snapped a six-game losing streak to their NL East rivals. The Braves won their fifth straight division title last year after sweeping New York on the final weekend of the regular season.

Daniel Vogelbach hit an RBI double in the nightcap and Starling Marte had a run-scoring single to stake the Mets to a 2-0 lead. Drew Smith (2-1) tossed 1 1/3 hitless innings in relief of Megill, who carried a shutout into the sixth before giving up a three-run double to Eddie Rosario.

Jeff McNeil homered leading off the eighth to provide insurance for the Mets.

David Robertson worked two scoreless innings for his sixth save — the fourth six-out save of his career.

CUBS 5, NATIONALS 1: Dansby Swanson hit a two-run homer and Drew Smyly delivered seven solid innings as Chicago won at Washington.

Swanson went 3 for 5, including a double and his second homer of the season. The 389-foot blast to left-center in the fifth inning made it 4-1 — a welcome advantage for the Cubs, who snapped a three-game skid.

AMERICAN LEAGUE

GUARDIANS 3, YANKEES 2: Josh Naylor hit a two-run single and Mike Zunino drew a go-ahead, bases-loaded walk in a three-run, ninth-inning rally that lifted Cleveland to a win at New York.

Domingo Germán took a one-hitter and a 2-0 lead into the ninth. But New York lost for the sixth time in eight games and dropped to 15-15, the Yankees’ first time at .500 since they were 1-1.

Steven Kwan singled with one out, and Yankees Manager Aaron Boone was booed when he went to the mound to bring in Clay Holmes.

The reliever bobbled Amed Rosario’s dribbler to the third-base side for an error and allowed a single to José Ramírez that loaded the bases.

Naylor, taunted by Yankees fans during last year’s Division Series, singled to right for Holmes’ second blown save in six chances.

Wandy Peralta relieved and walked Josh Bell, reloading the bases, then struck out Andrés Giménez. Zunino fouled off a pair of full-count sinkers, then took an inside change-up.

Enyel De Los Santos (2-0) got the final two outs of the eighth in relief of Cal Quantrill, throwing one pitch and picking off a runner. Emmanuel Clase got three straight outs for his 10th save in 12 chances.

NOTES

PHILLIES: Bryce Harper is expected to return to the lineup on Tuesday, 160 days after undergoing Tommy John surgery on his right elbow.

The two-time National League MVP indicated on Instagram that an appointment with Dr. Neal ElAttrache on Monday went well and that he was cleared to return.

The timing of the return would complete a stunning recovery for Harper. The Phillies said when Harper had surgery on Nov. 23 that he was expected to return around the All-Star break in mid-July.

METS: Carlos Carrasco could return to the Mets next week, potentially making whole a rotation that has been ravaged by injuries this season.

Carrasco, who has been sidelined since April 16 because of right elbow inflammation, began throwing last week. Manager Buck Showalter said the 36-year-old was “… kind of semi-penciled” in for the rotation cycle the Mets will begin Saturday.

Showalter said left-hander Joey Lucchesi will start Tuesday’s series opener against the Tigers in Detroit, after which co-aces Max Scherzer (suspension) and Justin Verlander (teres strain) are expected to return to the rotation for the final two games of the series.

Japanese rookie Kodai Senga, who last pitched on April 26, is scheduled to start Friday night at Citi Field against the Colorado Rockies. Showalter said the Mets hoped the early break would keep Senga — who pitched once a week in Japan — on a routine he’s accustomed to while also preparing him to potentially pitch every fifth or sixth day later in the season.

The Mets have an off day scheduled for next Monday before beginning a seven-game road trip to Cincinnati and Washington.

TRADE: The Cleveland Guardians traded left-hander Konnor Pilkington to the Arizona Diamondbacks for $100,000.

Pilkington appeared in 15 games for the AL Central champions last season, going 1-2 with a 3.88 ERA. The 25-year-old began this season with Triple-A Columbus before being recalled by the Guardians last week.

He made a relief appearance against Colorado on April 25, allowing one hit in two scoreless innings with two strikeouts.

Pilkington became expendable due to Cleveland’s abundance of young pitching talent. Rookies Logan Allen and Tanner Bibee have been impressive since arriving and appear to be part of the rotation going forward.

ASTROS: Right-hander Jose Urquidy was placed on the 15-day injured list with a sore right shoulder before the start of a series against the San Francisco Giants.

Urquidy left Sunday’s start in the sixth inning after feeling discomfort in the shoulder.

Urquidy is 2-2 with a 5.20 ERA in six starts. He allowed three hits and two runs to get the win Sunday night. In his previous start, he gave up seven hits and six runs over 2 2/3 innings.

Houston recalled right-hander Brandon Bielak from Triple-A Sugar Land to take Urquidy’s roster spot. Baker said Bielak would pitch out of the bullpen.

YANKEES: Captain Aaron Judge went on the injured list because of a strained right hip, joining Giancarlo Stanton, Harrison Bader and third baseman Josh Donaldson on the sideline.

New York announced the move before Monday night’s series opener against Cleveland and made the move retroactive to Friday. Judge is eligible to be activated for the May 8 series opener against Oakland.

Judge was hurt last Wednesday when he landed hard while making an awkward headfirst slide at Minnesota on his 31st birthday. He remained in the game and started Thursday at Texas, then left in the fourth inning after striking out twice.

A four-time All-Star and the reigning AL MVP, Judge is batting .261 with six homers and 14 RBI in his first season after signing a $360 million, nine-year contract.

Judge is on the injured list for the seventh time since making his debut in 2016, He stayed healthy last year and hit an American League-record 62 home runs, batting .311 with 131 RBI, tying the Mets’ Pete Alonso for the major league lead.

• Right-hander Jonathan Loáisiga will have arthroscopic surgery to remove a bone spur from his pitching elbow and likely will be sidelined until August.

Manager Aaron Boone said head team physician Dr. Christopher Ahmad will operate Tuesday and Loáisiga will not be able to throw for 3 to 6 weeks. Loáisiga, 28, had been out since April 5 with right elbow inflammation.

Center fielder Harrison Bader could be activated during the series against the Guardians. He has hasn’t played for the Yankees since a spring training game on March 8 because of a strained left oblique. Bader has played in seven minor league rehabilitation games, hitting .105 (2 for 19).

Right-hander Luis Severino, who hasn’t pitched since March 21 because of a right lat strain, is to throw 45-50 pitches Wednesday for Class A Tampa in his first minor league rehab appearance. Boone said the 29-year-old could be back with the Yankees in two to three weeks. He likely will get two or three more minor league starts, at Double-A Somerset and Triple-A Scranton/Wilkes-Barre.

Right-hander Lou Trivino, sidelined by a strained right elbow, went to California to be examined by Dodgers head team physician Dr. Neal ElAttrache.

Josh Donaldson, who strained his right hamstring on on April 5, took ground balls hit directly at him at third but is not yet being required to make lateral movements.

GIANTS: The San Francisco Giants placed shortstop Brandon Crawford and outfielder Mike Yastrzemski on the 10-day injured list before the start of a series against the Houston Astros.

Crawford, who has a strained right calf, was injured in the fourth inning of San Francisco’s 16-11 loss to San Diego Saturday night in Mexico City. His stint on the IL is retroactive to Sunday.

The 36-year-old Crawford has struggled this season, hitting .169 with four homers and 10 RBI.

Yastrzemski was shelved with a left hamstring strain. He was injured in Sunday’s 6-4 loss to the Padres while diving to try and catch a ball hit by Matt Carpenter in the eighth inning.

A grandson of Hall of Famer Carl Yastrzemski, Mike is batting .292 with five homers and 14 RBI.

The Giants recalled outfielders Cal Stevenson and Brett Wisely from Triple-A Sacramento.
