But afterward, Cespedes delivered some sobering news that despite his return from the disabled list, he could need an offseason procedure that would sideline him for part of next season.
Cespedes was activated after missing over two months with a right hip flexor strain, but it's his heels that have him worried.
"Cespedes says that the cause of his medical issues is calcification in both heels. He says the only way to fix the issue is surgery. He's considering it for the off-season, but the recovery time is apparently 8-10 months," Mets field reporter Steve Gelbs said in a tweet after the game.
Cespedes shrugged when asked if he'd be able to finish the season.
Mets manager Mickey Callaway left Cespedes out of Saturday's starting lineup and said Friday's comments were news to him. "(I'm) not quite exactly sure what he said," Callaway said, deflecting further questions.
Callaway said Cespedes arrived at the ballpark "pretty sore" on Saturday, a development he called "concerning."
Cespedes, 32, is batting .262 with nine home runs and 29 RBIs in 38 games this season. He played in just 213 games total over the previous two seasons with the Mets and is owed nearly $60 million over the next two seasons.
