The Yankees made a trio of roster moves before Monday’s series opener against the Royals, highlighted by the impending club debut of left-hander Aroldis Chapman.

Please, help us figure this out.

The Red Sox had a batting barrage on Monday night at Fenway Park, riding a monster night by Jackie Bradley Jr. to a 14-7 victory over the slumping Sonny Gray and the Oakland Athletics.

J.T. Realmuto launched a 409-foot drive that cleared the wall in center field at Marlins Park in the second inning Monday night against the Brewers, but his would-be two-run homer was overturned to a RBI single because he passed Marcell Ozuna at first base.

In a bizarre exchange during the ninth inning of the Nationals’ 5-4 win on Monday, Bryce Harper was ejected by home-plate umpire Brian Knight for yelling from the dugout after Danny Espinosa was called out on strikes.

This no doubt is a strange place for the Royals. With Monday’s 6-3 loss to the Yankees, Kansas City fell to 15-16 on the season, the first time they’ve been below .500 since July 22, 2014, when they were 49-50.

Commissioners Rob Manfred of Major League Baseball and Adam Silver of the National Basketball Association stood alongside former National Football League Commissioner Paul Tagliabue during a cocktail reception before Monday night’s “Lead Off for a Cure” fundraiser that raised $1.2 million for autism awareness and research at the Metropolitan Museum of Art.<p>

An appointment with team orthopedist Dr. David Altchek in New York City revealed nothing unexpected in Mets catcher Travis d’Arnaud’s right shoulder. Altchek diagnosed d’Arnaud with the same strained right rotator cuff that landed him on the disabled list April 26 and forced him to cut short a throwing program over the weekend.

THIS IS MY DIRT.

Alex Colome has stepped up to fill a need, and he’s done so in admirable fashion.

Major League Baseball is starting an effort this weekend to increase participation in baseball. One necessary ingredient is a suitable playing field. On Monday, a joint venture between Scotts and Major League Baseball brought Hall of Famer Cal Ripken, Jr., to Ladson, South Carolina and Tom Conley Park, beginning a national program involving youth baseball fields across America.

Red Sox ace David Price had a chance to put some mechanical adjustments in motion by throwing a bullpen session at Fenway Park on Monday — three days before he makes his next start against the Astros.

Kids will run the bases again this weekend. In fact, they will run just about everything.

Because you can never watch this enough.

Big story in San Diego, in all ways, big swing. Long ball for Bartolo Colon, even longer trip around the bases. Long trip for him to this night, period.

Carlos Santana and Mike Napoli homered, and the Indians used a fifth-inning rally to pull off a 5-4 comeback win over the Royals in a Mother’s Day divisional clash on Sunday at Progressive Field.

Tyler Goeddel and Andres Blanco delivered back-to-back RBI doubles in the decisive eighth-inning to rally the Phillies to a series-clinching 6-5 win over the Marlins on Sunday afternoon at Marlins Park.
