Bob Gibson is not only the greatest Cardinal pitcher of all time, but one of the greatest pitchers ever. He overcame asthma as a child to become a proficient athlete (he left the Harlem Globetrotters to play baseball). He refused to leave a game after Roberto Clemete broke his leg with a line drive. He is the all-time Cardinals leader in wins (251) and strikeouts (3,117), innings pitched (3,884.1) complete games (255), shutouts (56) and hit-batsman (102).
An eight-time All Star, and two-time Cy Young Award winner, Gibson was one of the most feared pitchers of his time described by players as simply "terrifying." He glared at opposing hitters, threw inside at will and was known for working extremely fast. Teammate Curt Flood said he could throw a baseball through a brick wall.
He won the MVP award in 1968 after going 22-9 with a 1.12 ERA, the lowest ERA ever with 300 or more innings pitched.
But for as great as he was in the regular season, Gibson is considered the greatest World Series pitcher ever. His eight complete games are an all-time record. His 17 strikeouts in Game 1 in 1968 is also a record.
He lost his first World Series game in 1964 and then rattled off seven consecutive World Series wins (another record). Those seven wins are also a Cardinals record, along with a ridiculous 1.89 ERA and 92 strikeouts.
