Lucky 13? Jurrjens latest to start for Rockies

DENVER -- Two days after being acquired from the Reds, right-hander Jair Jurrjens will make his Rockies debut Friday, becoming the 13th different starter to pitch for Colorado this season.

Jurrjens, 28, most recently made two appearances (one start) for the Orioles in 2013, logging four earned runs over 7 1/3 innings pitched. But he's battled injuries and ineffectiveness since leading the National League in wins and ERA at the All-Star break for the Braves in 2011.

The former All-Star was acquired for Double-A first baseman Harold Riggins Wednesday. Jurrjens never reported to Triple-A though, suggesting that the Rockies had always planned him as the replacement for left-hander Christian Friedrich, with Friedrich being optioned to make room for Nolan Arenado's return to the roster on Thursday.

Jurrjens' last start with Triple-A Louisville came on June 28, meaning he'll be on normal rest for his Rockies debut. He pitched seven innings of one-run ball, which was enough for Rockies manager Walt Weiss not to put any restrictions on him entering Friday.

"I'm not going to tie a specific pitch limit to him," Weiss said. "We'll just have to watch and see how it goes and play it by ear."

In six starts in Triple-A this season, Jurrjens has struck out 27 and surrendered 42 hits, 13 walks and 17 earned runs over 34 1/3 innings pitched.

Friday's originally-scheduled starter, left-hander Jorge De La Rosa, has been pitching through back issues all season, and will be given an extra day of rest before starting on Saturday.
