Diamondbacks Sign Ricky Karcher To Minor League Deal

The D-Backs have signed reliever Ricky Karcher to a minor league contract, according to Matt Eddy of Baseball America. The Snakes also brought back Humberto Castellanos on a non-roster deal.

Karcher joins the second organization of his career. The Reds selected him in the 13th round of the 2017 draft. The 6’4″ righty moved to the bullpen full-time in 2021. He has shown the ability to miss plenty of bats in the minor leagues but also demonstrated significant control issues. In parts of six minor league seasons, he owns a 26.4% strikeout rate while walking a massive 20.4% of batters faced.

Despite the strike-throwing concerns, Cincinnati added Karcher to the 40-man roster last offseason. That kept him out of the Rule 5 draft. They called him up for the first time in early June. He pitched once, tossing a scoreless inning against the Royals. Karcher averaged just under 98 MPH with his fastball in that appearance, pointing to the power arsenal he has shown in the minors.

That wasn’t enough to hold his roster spot with the Reds. The 26-year-old had a rough season at Triple-A Louisville, where he walked almost a quarter of his opponents over 60 1/3 innings. He posted a 4.77 ERA in 51 outings there, with Cincinnati outrighting him from the 40-man around the All-Star Break. Karcher qualified for minor league free agency at season’s end.

Castellanos is a depth starter who logged 100 2/3 MLB innings with the Astros and D-Backs between 2020-22. A soft-tossing control specialist, he owns a 5.45 ERA with a modest 16.6% strikeout rate. The right-hander underwent Tommy John surgery in August 2022. Arizona ran him through waivers last offseason and he missed this year rehabbing. If he’s healthy next spring, he could head to Triple-A Reno as rotation or long relief insurance.
