Metro Boomin Partners with MLB Network for Opening Day

Young Metro Boomin is fired up to play ball -- he's partnered with MLB Network to be its voice of Opening Day!!!

The diamond-selling superproducer dropped off a video Thursday morning ... detailing the grueling 162-game regular season with shots of MLB stars like the NY Mets' Justin Verlander, NY Yankees' Aaron Judge, Los Angeles Angels' Shohei Ohtani, Miami Marlins' Jazz Chisholm Jr. and more.

Metro's airtime makes good use of his hit songs "On Time" and "Trance" from his Billboard chart-topping "Heroes & Villains" album ... and also doesn't shy away from his allegiance to his hometown St. Louis Cardinals, rocking their ballcap in a recording studio.

MLB Network tells TMZ it's "thrilled to partner with Metro Boomin for Opening Day, and we’ll continue to explore opportunities to work with him throughout the season."

“You can’t beat this time of year," Metro quips in the vid. "Everybody’s staring at 162. 162 chances to make that beautiful music you can’t get anywhere else. Play ball.”
