Phillie pitching staff, Philadelphia baseball writers nicknamed Seminick "Grandpa Whiz." On August 12, 1950, in a game against the Giants, Seminick became irritated after Eddie Stanky repeatedly waved his arms while Seminick was batting. Stanky was eventually ejected from the game, but Seminick took out his frustrations on Bill Rigney, Stanky's replacement at second base. After he reached base on an error in the fourth inning, he slid hard into second base, crashing into Rigney and causing him to fall over. A nearly ten-minute brawl erupted between the teams, which required police intervention and resulted in the ejection of Seminick and Rigney from the game. The Phillies went on to win 4–3. Seminick enjoyed his best season in 1950, hitting for a .288 batting average with 24 home runs and 68 runs batted in. Seminick broke his ankle late in the season, but continued to play with the injury until the Phillies lost to the New York Yankees in the World Series. Future Hall of Fame pitcher, Robin Roberts said of Seminick,"If you had to pick a guy in the clubhouse who was our leader that year, it would be Andy. He always played hard, and that was his best year by far". In 1951, Seminick was beaned by a Max Lanier fastball, diminishing his ability to play. He was traded to the Cincinnati Reds for catcher Smoky Burgess, playing there from 1952 until the early part of the 1955 season. In 1955, he was once again traded for Burgess, returning to the Phillies, where he led National League catchers with a .994 fielding percentage. He played two more years before ending his playing career at the age of 36 after the 1957 season. Career statistics In a 15-year major league career, Seminick played in 1,304 games, totaling 953 hits in 3,921 at bats for a .243 batting average, with 164 home runs and 556 runs batted in. He threw out 44.6% of the base runners who tried steal a base on him, 16th on the all-time list.
