DENVER (AP) - The Colorado Rockies bolstered their infield by acquiring veteran second baseman Mark Ellis from the Oakland Athletics on Thursday.
The Rockies sent minor league right-hander Bruce Billings and a player to be named to Oakland for the 34-year-old Ellis and cash.
Ellis wasn't expected to be available for an afternoon game against the White Sox.
The Rockies have searched for stability at second base all season, trying out Jose Lopez - before he was designated for assignment - along with Chris Nelson and Jonathan Herrera. Eric Young Jr. has also played there.
Ellis is batting .217. He went on the disabled list with a hamstring injury and when he returned, rookie Jemile Weeks was Oakland's new starter at second base.
Billings spent most of the season at Triple-A.
