If Betancourt misses time

Colorado Rockies closer Rafael Betancourt is expected to undergo an MRI Wednesday on a groin that has bothered him for nearly a month. He's 10-for-10 in save opportunities and the club is just a game out of first place in the American League West. If Betancourt has to hit the disabled list, the Rockies will have to look elsewhere in the ninth inning, and manager Walt Weiss isn't sure just yet which direction he'll go.
