Rockies recall Sammy Peralta from Albuquerque, place Ryan Feltner on IL

Ryan Feltner’s right ulnar nerve inflammation forced the Rockies to make another pitching pivot Friday, and the first club to benefit was Sammy Peralta. Colorado placed Feltner on the 15-day injured list, retroactive to April 23, and recalled Peralta from Triple-A Albuquerque just before opening a three-game series against the Mets, a move that again underscored how thin the Rockies’ staff has become.

Peralta arrived with the kind of Triple-A line that can push a reliever onto a major league roster quickly. The left-hander, claimed off waivers from Milwaukee on April 4 and optioned to Albuquerque that day, went 4-0 with a 3.72 ERA in seven relief outings for the Isotopes. In 9.2 innings, he posted a 1.09 WHIP and struck out seven, numbers that fit the Rockies’ immediate need for a fresh left-handed arm in a bullpen that has been absorbing one transaction after another.

Feltner’s absence matters because Colorado had been leaning on him for rotation stability. The right-hander made five starts this season, and his latest came April 23 against San Diego, when he allowed two runs over two innings. That short outing now reads as a prelude to the IL move, and it leaves the Rockies searching again for innings in a staff that has been battered by injuries.

The roster churn has been relentless. Colorado recalled Seth Halvorsen from Albuquerque on April 23, claimed Blas Castaño off waivers from Seattle on April 21 and activated José Quintana from the 15-day injured list on April 15. To clear space for Peralta on the 40-man roster, the club transferred McCade Brown to the 60-day injured list. In a month defined by shuffling arms between Colorado and Albuquerque, Peralta became the latest player pulled upward by necessity, not luxury, as the Rockies tried to stabilize a pitching staff that entered the day at 10-16.
