Salvador Perez drove in a career-high six runs on a pair of homers, including a grand slam, as the Kansas City Royals moved within a game of the first-place Cleveland Guardians in the American League Central with Monday's 9-4 victory that capped a doubleheader sweep.

The surging Royals, winners of nine of their last 12 games, won the opener by a 4-3 score on Bobby Witt Jr.'s tie-breaking solo homer in the eighth inning.

Kansas City trailed 3-0 early in the nightcap but battled back to take a 5-4 lead on Perez's first homer of the game, a solo blast off Cleveland starter Logan Allen in the fifth inning. The All-Star catcher put the contest out of reach an inning later with a grand slam off Tim Herrin that marked his 17th career multi-homer outing, tied with Hall of Famer George Brett for the most in Royals' history.

Perez, who went 3 for 3 in the opener, also knocked in a run with a third-inning groundout that plated Maikel Garcia, who led off with a single and took third on a double by Witt.

Garcia and MJ Melendez each had three hits for Kansas City in the second game, while Paul DeJong went 2 for 4 with a solo homer.

The scuffling Guardians lost for the eighth time in 11 games despite three doubles and an RBI from Jose Ramirez in the nightcap. Daniel Schneemann had two hits for Cleveland, including a solo homer.

Cleveland is now 0-8 in doubleheader games this season.

In the opener, Witt drove a pitch from reliever Hunter Gaddis into the left field seats to give the Royals a 4-3 edge in the top of the eighth inning. John Schreiber and Lucas Erceg protected the one-run lead from there, with Schreiber earning the win and Erceg recording his eighth save with a scoreless ninth.

The Royals had taken a 3-2 lead on Melendez's three-run homer in the fourth inning, but the Guardians pulled even when Ramirez doubled in the seventh and later scored on Josh Naylor's single.

Jansen makes history, plays for the Blue Jays and Red Sox in same game

Danny Jansen became the first player in MLB history to appear for both teams in the same game when the Toronto Blue Jays and Boston Red Sox completed a previously suspended contest.

Jansen was a member of the Blue Jays when a June 26 matchup with the Red Sox was suspended in the second inning due to rain. He was traded to Boston on July 27 and inserted into the Red Sox's lineup when the game resumed Monday to accomplish the unprecedented feat.

The catcher's old team got the better of his current one, however, as Toronto posted a 4-1 win in the suspended game before dealing the reeling Red Sox a 7-3 defeat in Monday's regularly scheduled contest.

George Springer homered in both games, including a three-run shot in the fifth inning that erased a 1-0 deficit for Toronto in the nightcap.

Springer followed a double by Leo Jimenez and a walk to Steward Berroa with an opposite-field blast off Brad Keller to give the Blue Jays a 3-1 lead. Toronto scored twice more in the fifth on an RBI single from Addison Barger and a run-scoring double by Ernie Clement.

The big inning helped Jose Berrios (13-9) win his fourth straight start after the Toronto hurler held the Red Sox to three runs - two earned - and struck out six over 7 2/3 effective innings. Brendon Little relieved Berrios and tossed 1 1/3 scoreless innings for his first major league save.

Toronto has now won five straight in addition to the suspended game, while Boston has dropped four in a row along with the makeup game and is now five games out of a play-off spot in the AL.

Jarren Duran also homered in both games for Boston. The All-Star outfielder accounted for the Red Sox's lone run in the suspended game with a solo homer, then went 3 for 4 with a two-run shot in the follow-up meeting.

Springer's solo homer off Nick Pivetta in the suspended game snapped a scoreless tie in the seventh inning, and the Blue Jays scored three more times in the eighth on Vladimir Guerrero Jr.'s two-run double and an RBI double from Barger.

Pivetta (4-5) took the loss despite striking out 10 in six innings. The Boston right-hander allowed three runs - two earned - and just four hits.

Harper's hit in 10th puts Phillies over Astros

Bryce Harper's run-scoring single off Josh Hader in the 10th inning lifted the Philadelphia Phillies to a 3-2 comeback win over the Houston Astros in the opener of a three-game interleague series between division leaders.

After Philadelphia center fielder Johan Rojas made a diving catch with a runner at third to keep the game at 2-2 in the top of the 10th, Harper stepped to the plate with runners at first and second in the bottom of the inning and sent a ground ball through the infield. Kyle Schwarber beat the throw home from Houston right fielder Ben Gamel to score the deciding run and give the National League East-leading Phillies their third straight win.

Philadelphia trailed 2-0 after four innings, but closed the gap on Brandon Marsh's solo homer in the fifth and tied it in the sixth when Harper doubled and later scored on a Nick Castellanos single.

The Astros had gone ahead with two runs in the fourth. Victor Caratini drew a walk against Philadelphia ace Zack Wheeler and Gamel followed with a single, and both runners came home when Shay Whitcomb delivered a two-out double to left.

That was the only rough inning for Wheeler, who permitted two runs and struck out six over six frames.

Ronel Blanco worked 5 2/3 innings for Houston and also surrendered two runs while striking out five.

The Astros lost for the fifth time in seven games and had their lead atop the AL West shrink to 3 1/2 games after the second-place Seattle Mariners recorded a 5-1 win over the Tampa Bay Rays on Monday.

Kyle Schwarber hit another leadoff home run and All-Star Matt Strahm struck out Shohei Ohtani in a key spot as the Philadelphia Phillies defeated the Los Angeles Dodgers 4-3 for their major league-leading 60th win on Wednesday night. 

The Phillies have won the first two games of this three-game series between division leaders. At 60-32, only the 1976 team (88 games) reached the 60-win mark faster in a season in franchise history.

Philadelphia won without All-Star slugger Bryce Harper, who sat out with a bruised left hand after he returned for Tureday’s10-1 win following a nine-game absence. Harper was hurt at an unspecified point, through he clearly grabbed his hand and hunched over in pain on a second-inning chopper by Miguel Rojas.

Strahm entered with one out in the seventh and the Phillies holding a 4-2 lead. With runners at the corners, he struck out Ohtani and retired Teoscar Hernandez on a fly out to escape the jam.

The Dodgers scored a run in the eighth on Rojas’ RBI single, but Jeff Hoffman tossed a scoreless ninth for his ninth save.

Schwarber’s homer off Gavin Stone was his 39th career leadoff homer and 18th overall this season.

Valdez pitches Astros past Marlins

Framber Valdez struck out a season-high 10 over seven stellar innings and rookie Joey Loperfido homered and tripled to propel the Houston Astros to their eighth straight home win, 9-1 over the Miami Marlins.

Valdez allowed six hits – all singles – and walked one to win his third straight decision.

Loperfido hit a two-run homer to highlight a four-run second off Bryan Hoeing and had his first career triple in the fourth.

Yainer Diaz had three hits and three RBIs for the Astros (48-44), who have won eight of 11 to match a season high at four games over .500.

Perez’s home runs help Royals sweep

Salvador Perez homered in both games and MJ Melendez hit a solo shot in the nightcap as the Kansas City Royals beat the St. Louis Cardinals 8-5 for a sweep of their day-night doubleheader.

Garrett Hampson had two-run double to back a strong start by Alec Marsh in the Royals’ 6-4 victory in the early game.

Kyle Isbel homered in the second game and James McArthur pitched the ninth for his second save of the day and 17th of the season.

Kansas City notched its 50th and 51st wins of the season after it totaled just 56 victories all last season.

Nolan Arenado, Alec Burleson and Paul Goldschmidt homered in the opener for the Cardinals, while Lars Nootbaar went deep in the nightcap. St. Louis entered the day having won four of five.
