LEADING OFF

A look at what’s happening all around the majors today:

BACK TO WORK: Matt Harvey rejoins the Mets after serving a three-day suspension imposed by the team for not showing up at Citi Field for Saturday’s game. New York manager Terry Collins said Harvey will have to explain what happened to his teammates. “You stand up, be accountable and move on. And you know what? People forget about it,” Collins said.

NOT YET: Angels outfielder Mike Trout is still slowed by a tight left hamstring and isn’t ready to play. Trout was out of the lineup for the fourth time in five games for the series opener at Oakland. An MRI on the two-time AL MVP showed no damage. WATCH AND LEARN: Dodgers left-hander Julio Urias has been wild but effective in his first two starts this season, posting an 0.84 ERA but walking eight in 10⅔ innings. The 20-year-old could learn a thing or two from his next opponent, Ivan Nova. The Pirates right-hander has allowed just four walks in 17 starts since Pittsburgh acquired him from the Yankees last season — a 106⅔-inning stretch. SO LONG, SLUGGER: Ryan Howard might have taken his last swings after Atlanta released the 37-year-old from his contract at Triple-A Gwinnett. The Braves signed Howard shortly after the season began, hoping he might boost their bench. But the first baseman hit just .184 with one homer and five RBIs. Howard was the 2006 NL MVP and has 382 career home runs.
