Jorge De La Rosa, the Rockies’ all-time leader in victories and strikeouts, and the man who proved that a pitcher could succeed over the long run at the hitter’s paradise known as Coors Field, will most likely be making his final start of the season Tuesday night against the St. Louis Cardinals.

And because De La Rosa, 35, is in the final year of a two-year, $25 million contract, it could well be his final start ever in a Rockies uniform.

“This will most likely be the last start for Jorge, this season,” manager Walt Weiss said prior to Tuesday night’s game at Coors Field, explaining that Rockies will go from their current six-man rotation to a five-man staff through the club’s final 10 games of the season.

“It’s been quite a run for Jorge … and we don’t know what’s going to happen next year,” said Weiss, who’s also in the final year of his contract. “This guy has been a bit of trailblazer, showing people that you can pitch at Coors Field, and doing it better than anybody else in franchise history. It says a lot about his competitiveness, his work ethic and his ability to execute a game plan. It’s really a storied career in a Rockies uniform.”

De La Rosa, a left-hander acquired on April 30, 2008 in a below-the-radar trade with the Kansas City Royals, will make his 200th career start in a Rockies uniform Tuesday night. His 86 victories are the most for any Rockies pitcher, as are his 1,173 strikeouts.

His record at Coors Field is 53-19, a .736 winning percentage that Weiss called “absurd.”

“He’s the poster boy for showing that you could pitch here, at an offensive park, at altitude,’ Weiss said. “A lot of it has to do with his competitiveness. Jorge never gives in.”

De La Rosa used a good fastball an an effective split-finger changeup to carve out an overall career record of 96-80 with a 4.59 ERA in 240 starts. He’s also made 65 big-league relief appearances, going 5-3 with a 4.96 ERA out of the bullpen. Weiss said De La Rosa would be available out of the bullpen the rest of this season.
