The 36-year-old appeared in 52 major-league games for the Rockies last season, but he was designated for assignment in August after struggling both defensively and at the plate. Given Iannetta's past experience, he'll likely be a non-roster invitee for spring training.

The move didn't come as a surprise since the veteran has struggled defensively this season and has had a subpar year at the plate, recording a slash line of .222/.311/.417 with 54 strikeouts. The Rockies selected the contract of catcher Dom Nunez in a corresponding move.

Colorado plans to call up Dom Nunez from Triple-A Albuquerque to take Iannetta's spot as the backup behind top catcher Tony Wolters. Though Iannetta was valued last season for his game-calling skills and framing, he's taken a step back by most defensive metrics in 2019 and hasn't made up for the difference with the bat, as his 18 wRC+ is his worst mark for any year in which he's logged at least 100 plate appearances. Once he's removed from the 40-man roster, Iannetta seems likely to go unclaimed off waivers and could ultimately opt for free agency.

Iannetta will pick up his second start in three games, but he'll likely need to turn in an extended stretch of quality performances before seriously threatening Tony Wolters' perch atop the catching depth chart. The 36-year-old sports a meager .715 OPS on the season and is slashing a putrid .088/.184/.118 since the All-Star break.
