Colorado optioned Castano to Triple-A Albuquerque on Tuesday.
Castano made five appearances with the big-league club after being called up Sept. 1. Over 6.2 innings, the 28-year-old posted a 2.70 ERA, 1.20 WHIP and 4:3 K:BB. The Rockies reinstated Kyle Freeland (neck), leading to the team's removal of Castano from the active roster.

The Rockies recalled Castano from Triple-A Albuquerque on Tuesday.
Castano has logged a 3.92 ERA and 17:6 K:BB across 20.2 innings with the Rockies this season. The 27-year-old is likely to be used as a multi-inning reliever in Colorado.

Castano is expected to be recalled from Triple-A Albuquerque on Tuesday when rosters expand, Kevin Henry of The Denver Gazette reports.
Castano worked to a 3.93 and 1.36 WHIP with 14 strikeouts over 18.1 innings (nine appearances) during his last stint in the big leagues. He'll likely be asked to provide support out of the bullpen once his promotion becomes official Tuesday.

The Rockies reinstated Castano (pectoral) from the injured list Saturday and optioned him to Triple-A Albuquerque.
Castano has been on the injured list since late June due to a pectoral strain. He began playing in rehab games last Saturday and has since allowed four runs on four hits and two walks over 2.1 innings. Now fully healthy, the 27-year-old will remain in Triple-A for the time being but could return to the majors later in the year as bullpen depth.

Castano (pectoral) is expected to begin a throwing program next week, MLB.com reports.
Castano will need more than a week to build up as he works his way back from a right pectoral strain, so he doesn't appear to be in line to return from the 15-day injured list until after the All-Star break. Before landing on the shelf June 21, Castano turned in a 3.92 ERA, 1.35 WHIP and 17:6 K:BB in 20.2 innings over 10 appearances out of the Colorado bullpen.

The Rockies placed Castano on the 15-day injured list Sunday due to a right pectoral strain.
Castano will be eligible to return from the shelf July 3, but given the nature of his injury, he may need more than the minimum amount of time on the IL to make a full recovery. The 26-year-old had been occupying a low-leverage role in the Colorado bullpen since being promoted from Triple-A Albuquerque on May 21, recording one win and no holds or saves while pitching to a 3.93 ERA and 1.36 WHIP across 18.1 innings in nine appearances.
