No. 1: Darren Daulton
With the caveat that he's keeping the seat warm for Realmuto, Darren Daulton still stands as the greatest catcher in team history through the 2023 season. It's truly a shame that Daulton didn't become the team's regular catcher until he was 27 years old, because he could have really put up some numbers.
As it stands, 'Dutch' still managed to hit 20 home runs and drove in 100 runs a pair of times, even leading the NL in RBI (109) in 1992, when he finished sixth in MVP voting. Daulton also earned three All-Star selections and a Silver Slugger.
His legendary leadership of the 1993 club that came tantalizingly close to a World Series title endeared him to the fanbase in perpetuity. Here was a true Phillie who got down in the dirt and gave his blood and sweat to help the team win. People around here will never forget it.
Daulton actually served as the first designated hitter in team history, as well, when interleague play arrived in 1997. He would be traded to the Marlins that year, of course, and Phillies fans were overjoyed to see him win the World Series with them to cap off his career.
Darren Daulton stands atop this list for the time being but, no matter if and when he is passed by J.T. Realmuto or some other player down the road, Phillies fans will always remember the player and the man. There will never be anyone quite like Dutch.
