Joe Jammer was a groundskeeper for the Montreal Expos for 11 seasons, one of which was the 1984 campaign when Rose was on the team. He told Gallagher the hit king corked his bats as a player and had help from someone in the visitors' clubhouse at Olympic Stadium.
"Pete was too smart to deal with Expos equipment manager John Silverman [to cork his bats in the Expos' clubhouse]," Jammer said. "So Bryan Greenberg, who worked in the visitors' clubhouse, did it."
Jammer also said Greenberg told him Rose corked his bats throughout his career and that he was never checked "because he's a singles hitter."
Greenberg would not confirm such allegations, but an anonymous source did.
Rose played from 1963 through 1986 for the Expos, Cincinnati Reds and Philadelphia Phillies. He was a member of the Expos for only part of the 1984 season, but he reached the 4,000-hit milestone in their uniform.
From a statistical perspective, there is no doubt Rose belongs in the Hall of Fame. After all, nobody in Major League Baseball history has more hits than his 4,256, and he amassed three World Series titles, a National League MVP Award, an NL Rookie of the Year Award, three batting titles, two Gold Glove Awards and 17 All-Star selections.
Bartlett Giamatti banned him from baseball—with the Hall of Fame subsequently making banned players ineligible for election—for life for betting on games as Reds player-manager in 1986.
