"I think it's unpredictable given what will happen and I can't say I will play X, Y, Z amount of games," Cespedes said through an interpreter.
Cespedes underwent surgery on his right heel on Aug. 2. The procedure was to remove bone calcification in the heel. The surgery on Oct. 23 will be on his left heel.
"I feel very good. Even better than I was expecting," he said Sunday regarding his first surgery.
Cespedes, 32, was limited to 38 games this season. He hit .262 with nine home runs and 29 RBIs.
He is signed through the 2020 season and is scheduled to make $29.5 million in both 2019 and '20.
