The state of Colorado will never be called the place to find elite major-league pitching.
There have been some success stories. The biggest name is, of course, Roy Halladay who had dominant stints with both the Toronto Blue Jays and the Philadelphia Phillies.
The righty from Arvada West High School pitched a perfect game in the regular season and threw a no-hitter in the postseason. He won the Cy Young twice and was selected to the All-Star Game eight times. He is the man when it comes to pitchers from Colorado.
