Marlins Select Devin Smeltzer, Designate Eli Villalobos

The Marlins selected the contract of left-hander Devin Smeltzer, according to the Miami Herald’s Jordan McPherson (Twitter link).  In corresponding moves, lefty Daniel Castano was optioned to Triple-A, and right-hander Eli Villalobos was designated for assignment.

Smeltzer signed a minor league deal with the Marlins back in January, and the southpaw will now lock in a $1MM guaranteed salary for making the team’s Major League roster.  Once he appears in a game with Miami, it will mark Smeltzer’s fifth season in the big leagues, after spending his first four years with the Twins.  With a 3.99 ERA over 140 career innings, Smeltzer’s bottom-line results have been solid, even if advanced metrics haven’t been sold on his low-velocity and low-strikeout repertoire.

The left-hander has only a 16.6% strikeout rate at the MLB level, but he has shown solid control with a 6.4% walk rate.  Working as both a starter and a reliever, Smeltzer was a useful swingman for the Twins, and started 12 of his 15 appearances last season.  With Johnny Cueto on the 15-day injured list, Braxton Garrett has been filling in as part of Miami’s rotation, so Smeltzer could provide more starting depth.

The Marlins added Villalobos to their 40-man roster last November in advance of the Rule 5 Draft, protecting the 25-year-old from any teams intrigued by his impressive minor league numbers.  Over 61 1/3 innings at Double-A and 17 1/3 innings at Triple-A in 2022, Villalobos had a combined 2.86 ERA, 32.7% strikeout rate, and 9.4% walk rate.  Unfortunately, things haven’t gone nearly as smoothly for the righty this season, as Villalobos was rocked for an 11.57 ERA in 4 2/3 innings at Triple-A, with two homers allowed and as many walks (seven) as strikeouts.  These numbers might dissuade teams from making a waiver claim, but it’s possible a club might still be intrigued by Villalobos’ ability to miss bats.
