The Colorado Rockies made four roster moves prior to their Monday tilt against the Pittsburgh Pirates at Coors Field, according to Patrick Saunders of The Denver Post.
Catcher Nick Hundley, who has been out since taking a foul ball off of his mask on April 13, was activated from the seven-day concussion disabled list. He'll replace fellow backstop Dustin Garneau, who was optioned to Triple-A Albuquerque, on the Rockies' 25-man roster.
The Rockies also optioned Jordan Lyles, who allowed seven runs (five earned) in 2⅔ innings against the Dodgers on Sunday, to Albuquerque. Reliever Scott Oberg was recalled from Triple-A to take the bullpen spot of Chris Rusin, who will start in Lyles' place on Friday, per Saunders.
Hundley will likely resume his duties as starting catcher in place of Tony Wolters, who has performed admirably behind the plate but is hitting just .179 with a .482 OPS. In 28 plate appearances prior to his injury, Hundley hit .227/.393/.409. The 32-year-old veteran posted a .301/.339/.467 line with the Rockies in 2015, his best offensive season in five years.
Garneau fared well with the bat in his most recent stint with the Rockies, contributing four hits -- three doubles -- and a couple of walks in 12 plate appearances.
Lyles had a strong road start in Cincinnati but has been horrendous in Denver, allowing 15 earned runs in 10⅔ innings while walking 10 batters and striking out just five.
Oberg struggled in his debut season with the Rockies a year ago, walking nearly five batters per nine innings while posting a 5.09 ERA. The 26-year-old right-hander owns similar numbers this season through 7⅔ innings spanning six games thus far for Albuquerque.
Rusin joins the rotation after putting together a scoreless streak of 9⅔ innings across three appearances, during which time he's struck out six batters and walked only two. Last season with the Rockies, the 29-year-old southpaw as a starter produced a 5.62 ERA with 6.0 K/9 and 2.8 BB/9.
