The New York Mets left Pete Alonso out of the lineup Saturday, with manager Mickey Callaway suggesting the slumping slugger could be reeling from a busy All-Star break.

"He's a horse," Callaway said before the Mets took on the San Francisco Giants, according to Anthony DiComo of "But sometimes, you've got to take it out of their hands."

Alonso, who carried a .280 batting average into the All-Star break, is just 3-for-30 with 13 strikeouts since returning from Cleveland.

Callaway said his decision to sit Alonso for the first time since June 11 came after a discussion with Todd Frazier, who informed him how taxing the Home Run Derby could be. Frazier participated in the event for three straight years from 2014-16, winning it in 2015.

Alonso swatted 57 dingers in his Derby, including 23 in the final round to win it. The rookie played in the All-Star Game the next day.

"I don't feel worn down," Alonso said. "I gotta trust my coaches and the staff have my best interests - I know they have my best interests at heart. I hate off days, I want to be in there because I'm really competitive ... but I respect the decision."

Alonso has been one of the few bright spots in the Mets' disastrous campaign. Even with his recent struggles, the 24-year-old owns a slash line of .265/.358/.606 with 32 homers and 72 RBIs for the season.
