He went just 4-for-14 with no RBIs in Games 2 through 5 last year as the Phillies won both series in five games.
"We tried to crowd him," Phillies manager Charlie Manuel said.
Ramirez hit .311 with eight home runs and 40 RBIs in 66 games this season, but had three stints on the disabled list because of calf and hamstring injuries.
"I think he can still hit," Manuel said. "He's a pretty gifted hitter. He can definitely still hit."
Manuel said he never had problems with Ramirez when he worked with him with the Cleveland Indians, but he had him in the Minor Leagues and as a young player in the big leagues.
"You had to really communicate with him," he said. "As he got older, Manny became Manny. The more money he got, the more he hit, the more they let him be Manny."
