DENVER -- In the toughest place to pitch, but where he has been among the toughest pitchers, Joey Lucchesi got roughed up.
As the left-hander's second prove-it season nears an end, the thin air a mile high finally affected him.
The Rockies drove Lucchesi from the game with five runs before he could get the final out of the fourth inning and held on for a 10-8 victory Friday night at Coors Field.
Lucchesi's shortest outing of the season kept him from matching a career high with a third straight quality start.
It brought to an end a run of four starts in which he posted a 1.57 ERA and also a run of uncommon success in Colorado.
Entering Friday, pitchers had a collective 6.01 ERA at Coors Field this season, highest in the major leagues by almost a point over Camden Yards (5.19). Lucchesi's 1.56 ERA in three previous starts (three runs, 17 1/3 innings) in Denver was the second lowest among all active pitchers who had made at least three career starts there.
After Friday, he has a 4.71 career ERA at Coors Field.
That's how quickly things can get ugly at the ballpark where these two teams set a major league record by combining for 92 runs in their four-game series in June.
Friday got away from Lucchesi in a hurry.
The Rockies led 3-2 heading into the bottom of the fourth, on Nolan Arenado's two-run homer in the first and a Pat Valaika triple and Yonathan Daza sacrifice fly in the third. But Lucchesi had thrown just 32 pitches, the fewest he had taken to get that far into a game all season.
