The Rockies reinstated Estrada (thumb) from the 10-day injured list Friday.
The infielder hasn't seen the field since July 7 due to a thumb sprain, but he's ready to rejoin Colorado for Friday's series opener in Baltimore. Estrada has a .284/.312/.397 slash line with two homers in 29 games this season and should reclaim the starting job at second base now that he's healthy.
