Me too. If you notice, I had to carefully word the question with Houston, instead of Astros or the dead giveaway Colt .45's. I didn't remember the Roberts shutouts, I had to check after I read your post. My idea was simply a quick try at a Houston related trivia question, so I started checking the box scores beginning in 1962, and three games into the new franchise, Stone appeared. Then his next start a week later. Voila. I spent a grand total of 5 minutes researching this.
As with most trivia, I also learned something along the way, which is one reason it has been my lifelong hobby. Always something interesting if one will just do a little digging.
where do you find the individual box scores?
Roberts was hanging on trying to get 300 wins when he came to Houston. his FB was gone, but he could really pitch. the night i saw him, he was masterful--something like a 4-hit shutout, i think. on a better team, he might have gotten a few more wins. i remember one LA game in particular; he took a 2-1 lead into the 9th, but Gilliam spoiled it with a 2-run something. of course, the Astros did not score in the 9th. we traded him to the Os or somebody the next year, and he hung them up short of 300.
i like to look at the all-time roster in the media guide to see the famous and great who passed through Houston during their careers and played in at least one game.
