KANSAS CITY, Mo. (AP) — MJ Melendez hit a three-run home run in the fifth inning and had a career-high six RBIs to help the Kansas City Royals beat the Boston Red Sox 13-5.

The rookie Melendez blasted it an estimated 406-feet to right field, which bounced into the fountains to give the Royals a 5-0 lead.

Melendez is putting together quite the campaign after being called up on May 3. He’s hit 13 home runs on the year and has back-to-back homer games four times this season.

Among rookies, he’s hit the fifth most home runs this season and is just two behind teammate Bobby Witt Jr.
