The Astros franchise record for most stolen bases in a season belongs to Gerald Young which is why we'll be highlighting him today, prior to the 65th game of the 2012 season.
Young was acquired from the New York Mets along with Manuel lee for Ray Knight.He made his Major League debut with the Astros in 1987 at the age of 22. He would finish fith in the Rookie of the Year voting with a .321/.380/.380 line and 26 stolen bases.
The very next year he would set the Astros franchise record for most stolen bases in a season with 65. Breaking the 61 mark set by Cesar Cedeno in 1977. In 1989 Young contributed another 34 stolen bases, however, he also lead the league in caught stealing with 25. The year he set the stolen base record for the Astros, he had been caught 27 times which also had lead the league.
It appears Young was fast, but reckless.
From 1990 to 1992 Young would only play a part time role on the Astros ball club. He would wrap up his career with the Colorado Rockies and the St Louis Cardinals. Despite all that Young to this day still holds the stolen base record and looks to hold onto it for the foreseeable future.
