Using FanGraphs’ WAR metric, the Red Sox had one of the best catching groups in the American League in 2020 (1.7 fWAR), trailing only the White Sox (3.0 fWAR) and Royals (2.7 fWAR) for the league lead in that category.
The two backstops who saw just about all the playing time behind the plate for Boston this past season — Christian Vazquez and Kevin Plawecki — both put together solid campaigns in their own right.
Vazquez, 30, clubbed seven home runs in 47 games in addition to posting a wRC+ of 115 and leading all major-league catchers in FanGraphs’ Defense metric (8.3).
Plawecki, meanwhile, emerged as quite the serviceable backup with his new club as the 29-year-old slashed .341/.393/.463 with one homer and 17 RBI over 24 games and 89 plate appearances.
Excluding Jonathan Lucroy, who was released in September, the only other true catcher to see playing time for the Sox in 2020 was Deivy Grullon.
The 24-year-old out of the Dominican Republic was claimed off waivers by Boston from the Phillies on September 3 and only managed to appear in one game as the Red Sox’ 29th man in a doubleheader against Philadelphia on September 8.
Grullon went 1-for-3 with a walk and run driven in during the nightcap of that twin bill against his former team before he was optioned back down to the alternate training site in Pawtucket. SoxProspects currently lists Grullon as the Red Sox’ 30th-ranked prospect.
All three of Vazquez, Plawecki, and Grullon are already on Boston’s 40-man roster, but another backstop is expected to be added to said roster in the coming weeks. His name? Connor Wong.
One of the three players acquired from the Dodgers in the Mookie Betts/David Price trade from this past February, the 24-year-old Wong is eligible for this winter’s Rule 5 Draft, which means he would have to be added to Boston’s 40-man roster before November 20 in order to be protected from that.
Wong being added to the 40-man seems just about imminent at this point. Not only does the former third-round pick offer some versatility at different infield positions, according to The Athletic’s Peter Gammons, he also is “considered by [Jason] Varitek and their organization as a rising elite pitcher-first catcher.” On top of that, as noted by MassLive.com’s Chris Cotillo, “the Sox didn’t acquire [Wong] just to risk losing him.”
So here we have four appealing catchers, all of whom are already within the organization, which means we have not even touched upon catchers from outside the organization who could join the Red Sox in 2021.
One name in particular that comes to mind here would be none other than J.T. Realmuto, who is set to become a free agent for the first time in his career this winter.
Often regarded as the best catcher in baseball (BCIB), Realmuto would be quite the get for Red Sox chief baseball officer Chaim Bloom and Co. The 29-year-old is coming off a 2020 campaign with the Phillies in which he posted a .266/.349/.491 slash line to go along with 11 home runs and 32 RBI over 47 games played.
In addition to his superb offensive efforts, Realmuto is quite the defensive backstop as well, especially when it comes to pitch framing and throwing out runners. Just last year, the Oklahoma native threw out 47% of the runners who tried to steal against him, which was the best caught-stealing rate in baseball.
Even if the Phillies prioritize getting Realmuto to sign a new contract to keep him in Philadelphia, there may only be a handful of clubs who would be able to spend big on someone of Realmuto’s caliber coming off this pandemic-induced, 60-game season. The Red Sox would obviously be one of those clubs.
Of course, the Sox adding Realmuto only makes sense if Vazquez is not in Bloom’s future plans. The Puerto Rico native, who is signed through 2021 and has a team option attached for 2022, was linked to the Rays in the days leading up to the 2020 trade deadline back in August, but nothing ever came out of those rumored talks. Still, as again noted by Cotillo, Boston dealing Vazquez this winter “could definitely happen.”
As currently constructed, Vazquez and Plawecki stand as the Red Sox’ top two catchers at the major-league level, while the likes of Grullon and Wong could both begin the 2021 season at Triple-A Worcester.
Realmuto landing with Boston seems more of a long shot than anything right now, but things could obviously change as the offseason progresses.
