Betancourt throws successful sim game

DENVER-- Closer Rafael Betancourt threw a simulated game at Coors Field on Monday, another step forward as he recovers from an emergency appendectomy.

Betancourt had his appendix removed June 20 and has been on the 15-day disabled list since. But Rockies manager Walt Weiss said Betancourt was on track to make a rehab appearance with Triple-A Colorado Springs on Thursday.

"I think he threw close to 40 pitches, and it went well," Weiss said. "We'll see how he feels tomorrow, but the plan is for him to go out and pitch on Thursday. Then we'll go from there."

Lefty Rex Brothers has taken over closer duties in Betancourt's absence, converting nine straight opportunities.

Betancourt also reeled off four consecutive saves before being sidelined by injury and has converted 15 of 16 opportunities this year.
