No future Astros, only former Astros with birthdays today ~
RHP Doug Jones (55)
Originally drafted by the Brewers in the third round in 1978, Jones was a three-time All-Star for Cleveland before signing with Houston as a free agent in January of 1992. In 151 games for Houston in 1992 and 1993, he was 15-18 with a 3.02 ERA and a 1.198 WHIP. 1992 was the better of his two seasons with the Astros as his 11-8 record with a 1.85 ERA and a 1.012 led to his fourth All-Star appearance. In December of 1983, he was traded (along with RHP Jeff Juden) to the Phillies for LHP Mitch Williams. He earned one more All-Star nod for the Phillies in 1994 and would end his career in 2000 after playing 16 seasons for seven different teams.
C Jim Campbell (75)
Obtained by Houston in a trade with the Milwaukee Braves in February of 1961, Campbell played in 82 games for the Colt .45s in 1962 and 1963, hitting .222 with a 32% caught stealing percentage.
