The Red Sox win their 10th game in a row as they defeat the Blue Jays, 6 – 4, thanks to 5 RBIs by Mookie Betts. He hits a grand slam off J.A. Happ to cap a five-run 4th inning, at the end of an epic 13-pitch at-bat, then adds an RBI single in the 7th as the crowd chants “MVP! MVP!” The Sox have now won 66 games, the most before the All-Star break in team history.

The Indians also light up the scoreboard in winning the battle of Ohio, 19 – 5, over the Reds. Jose Ramirez homers twice and drives in 5, as Tyler Mahle gives up 7 runs in 2 1/3 innings and his successor, Tanner Rainey, another 8 runs in just two-thirds of an inning. IF Alex Blandino is called on to pitch mop-up duty in the 8th and is the only Reds pitcher not to allow a run.

The Rockies go on a scoring binge in crushing the Diamondbacks, 19 – 2. The Rox hit five homers, including two by Carlos Gonzalez and one by pitcher German Marquez, while position players Daniel Descalso and Alex Avila combine for 4 2/3 innings of relief in order to spare Arizona’s bullpen. D-Backs starter Shelby Miller does not make it out of the 1st inning, allowing 5 runs before exiting due to tightness in his elbow, and relievers Jorge De La Rosa and Yoshihisa Hirano are shelled for 7 and 4 runs respectively.

Not to be outdone, the Indians lose a game on a strange 9th-inning managerial gaffe. They lead the Reds, 4 – 0, coming into the top of the 9th, after a brilliant start by Trevor Bauer, but closer Cody Allen gives up 4 runs and loads the bases with two outs, prompting manager Terry Francona to call in lefty Oliver Perez to face Joey Votto. Trouble is, its not Perez who’s been warming up, but righty Dan Otero, the result of a miscommunication with pitching coach Carl Willis: Francona asked to get “OP” warmed up, whereas Willis understood “OT” (Otero’s nickname). Given a favorable match-up, Votto lines a 3-2 pitch into right-center field to clear the bases and send Cincinnati on its way to a 7 – 4 win.

The Astros get a walk-off win on a ball that barely travels two feet. With runners on first and second and one out in the 11th after the Astros have just tied the score at 5-all against the Athletics, Alex Bregman taps a ball that bounces off home plate, briefly rolls foul, before returning to fair territory. C Jonathan Lucroy picks it up and attempts to tag Bregman, who has not moved yet, but he somehow drops the ball. He then throws to 1B but his relay glances off Bregman’s helmet and past 1B Mark Canha, allowing Kyle Tucker to score the winning run from second base. “I think it was the softest ball anyone’s ever hit,” Bregman reflects after the bizarre play.
