MLB Lineups Today: Complete Batting Orders and Starting Pitchers for Mets vs. Red Sox, Padres vs. Blue Jays & More

MLB's narrative wheel keeps spinning on May 21, delivering a fresh slate of matchups with postseason energy in the air. At Fenway Park, the Mets and the Red Sox gear up for the rubber game of their interleague series, a battle that’s featured tight pitching duels and timely power hitting.

With Garrett Crochet is scheduled to start today and the Mets leaning on Pete Alonso’s steady bat, this one sets up as a fitting finale under the lights in one of baseball’s most iconic parks.

North of the border, the action shifts to Rogers Centre, where the Padres and the Blue Jays continue their early-season cross-league clash. San Diego arrives loaded with firepower, led by Fernando Tatis Jr. and a lineup that’s been one of the most explosive in the National League.

Toronto counters with homegrown slugger Vladimir Guerrero Jr. and a club desperate to turn around a sluggish start.
