“He did not reach out to management with any explanation for his absence,” Van Wagenen said in a statement. “Our attempts to contact him have been unsuccessful.”
Cespedes, 34, was the designated hitter for Saturday’s 7-1 loss to the Braves, going 0-for-4 with two strikeouts.
He was not listed in the original lineup for Sunday’s game, which began at 1:10 p.m. ET.
Cespedes had been out of the lineup for almost two years before Opening Day of this pandemic-shortened season because of a string of injuries to his feet and legs. He had served as the Mets’ designated hitter in eight games this season.
