James Mouton was selected by Houston in the 7th round of the 1991 amateur draft. He played for the Astros on the major league level from 1994 to 1997. By the next season he had traded to the Padres for Sean Bergman. After a year in San Diego he would play two more seasons, this time for the Brewers.
While checking out the internet to see what Mr. Mouton has been up to these days, I ran across a website for the Fort Bend Texans Sports Association, which feature several former Houston players. It seems Mouton was a guest coach recently. I believe I might have read once where he was coaching on the minor league level; then again, I might be confusing him with someone else.
