Former Red Sox catching prospect Ronaldo Hernández agrees to minor-league deal with Diamondbacks

Former Red Sox catching prospect Ronaldo Hernandez has agreed to a minor-league contract with the Diamondbacks, according to ESPN’s Kiley McDaniel. The deal comes with an invitation to major-league spring training.

Hernandez, 26, spent the last three seasons in the Red Sox organization after originally being acquired from the Rays alongside minor-league infielder Nick Sogard in the February 2021 trade that sent pitchers Chris Mazza and Jeffrey Springs back to Tampa Bay.

At that time, Hernandez was viewed as one of the top catching prospects in baseball. The native Colombian had already been added to the Rays’ 40-man roster in 2019 and maintained that status going into his first spring training with the Sox. He opened the 2021 campaign at Double-A Portland and posted an .825 OPS in 92 games there before earning a promotion to Triple-A Worcester in late September.

Hernandez spent the entirety of the 2022 season with Worcester as well, batting .261/.298/.451 with 27 doubles, 17 home runs, 63 RBIs, 50 runs scored, 21 walks, and 92 strikeouts over 105 games (437 plate appearances) for the WooSox. The right-handed hitter was called up by Boston on two separate occasions last year (once in April and again in August) but never got into a game, so he has yet to officially make his major-league debut.

The Red Sox removed Hernandez from their 40-man roster last December and subsequently outrighted him to the minor-leagues once he cleared waivers. He received an invite to big-league spring training, but was never really in consideration for a call-up this past season. Instead, he slashed .242/.336/.445 with 17 doubles, 17 homers, 70 RBIs, 49 runs scored, two stolen bases, 41 walks, and 69 strikeouts in 99 games (393 plate appearances) for Worcester while splitting time between catcher and designated hitter.

Hernandez, who became a free agent after hitting the open market last month, peaked as the No. 14 prospect in Boston’s farm system, according to SoxProspects.com’s rankings history. He carries with him a lifetime slash line of .279/.333/.461 with 91 home runs and 409 RBIs in 636 career minor-league games (2,616 plate appearances) dating back to 2015. At the Triple-A level specifically, Hernandez has batted .255/.319/.448 with 34 homers and 138 runs driven in across 211 games spanning 860 trips to the plate.

While defense has never been a strong suit for Hernandez, the 6-foot-1, 248-pound backstop should be able to provide the Diamondbacks with some bat-first catching depth in the upper-minors behind the likes of standout Gabriel Moreno and Jose Herrera (both of whom are currently on Arizona’s 40-man roster) heading into the 2024 season.

In the meantime, Hernandez has been playing winter ball for the Gigantes del Cibao of the Dominican Winter League. Coming into play on Wednesday, he has hit .245/.333/.283 with two doubles and three RBIs in 17 games (60 plate appearances) with the San Francisco de Macorís-based club.
