LEADING OFF

A look at what’s happening around the majors today: DUCKS ACROSS THE POND: High cheese has come to the land of high tea. The Red Sox and Yankees will begin their two-game series in London, with Boston’s Rick Porcello facing New York’s Masahiro Tanaka at Olympic Stadium, home of the West Ham soccer club. Hitters figure to have a jolly old time with the center field wall a cozy 385 feet away.

TWO-WAY RAY: Brendan McKay will make his major league debut on the mound for Tampa Bay. The two-way prospect was 3-0 with a 1.08 ERA in five games with Triple-A Durham, where he also spent time as the DH. Rays manager Kevin Cash said the left-hander will also pitch against the Yankees on July 5, and that discussions are on-going about how many at-bats the 2017 first-round pick will get while he’s with the big club. He’ll face Rangers right-hander Adrian Sampson (6-4) in his first start.

LEFT OUT: The Cubs are evaluating left-hander Cole Hamels after he left a start Friday with discomfort in his left side. Hamels worked one inning against Cincinnati and walked off after a warm-up pitch prior to the second. Hamels went seven innings in each of his previous five starts. He had a 1.00 ERA over that span, allowing four earned runs.

MIRACLE METS: In a pregame ceremony, the Mets will commemorate the 50th anniversary of their 1969 World Series championship. About 15 members of that team are expected back as New York hosts the Atlanta Braves. Jerry Koosman, Cleon Jones and Jerry Grote are among the former players planning to be on hand when the Miracle Mets receive the key to the city from New York Mayor Bill de Blasio.
