The Astros are down to those critical 57 games of the season - the final 57 games of the season. Craig Biggio has been hit by 83 pitches during the Astros final 57 games of the last 19 seasons, which gives him an average of slightly over 4.4 plunks per season, in the final 57 games of those seasons. However, a 4 plunk average shouldn't fill fans with a sense of security that the all time HBP record will be his by the end of this season. Biggio has only been plunked 3 or more times in the final 57 Astros games of the season in 11 of the last 19 seasons. But - in 2000 he only played in 1 of the last 57 Astros games of the season, and in his 24 game appearances in the final 57 Astros games of 1988, Biggio didn't get hit at all. Also, in 1994 the final 57 games of the season started at game 59 due to a labor dispute, and the 1995 season started late so the final 57 games of that year started at game 88.
During the final 57 games of the last 19 Astros seasons, Craig Biggio has been plunked most often on Tuesdays, with 15 plunks. In 1997, he got hit 19 times in the final 57 Astros games of the season, but last year he was only hit twice. If he were to get hit 19 times in the next 57 games, he'd be able to end his career with 304 HBPs, which obviously would be a number that would make the BBWAA and the Baseball Hall of Fame waive the 5 year wait for induction.
