Red Sox Video
Last week, the Red Sox made a couple of minor-league deals, and in our haste to break down the thousand or so swirling rumors about potential trades and free agent signings, we neglected to cover what really matters: Seby Zavala. The Red Sox added the 31-year-old catcher, along with utilityman Nate Eaton. The two moves make a lot of sense for a Red Sox team with an extremely strong core but some real holes in the lineup. Let’s start at catcher.
At the moment, Connor Wong and Mickey Gasper are the only catchers on the 40-man roster. Wong will almost certainly be catching about half the time in 2025. Gasper will not. The 29-year-old Gasper made his major-league debut in 2024, but he only played first and second in Boston. He’s struggled with injuries, and he might not even be a catcher anymore. He spent most of his time at DH in 2024. All of this to say that he probably won’t affect the catcher role much. (On the other hand, it's at least worth noting that he absolutely raked in the minors, running a .970 OPS with 12 homers over 92 double-A and triple-A games with a solid 90-mph average exit velocity and 42.7% hard-hit rate to boot.)
That meant that the Red Sox went into the offseason with a dire need to sign a catcher in free agency, and even they did so, the need for at least one backup. Enter Zavala. He’s not going to slot into the lineup, but he’s an excellent option for a third catcher. Zavala has a sterling defensive reputation, along with the numbers to back it up. Since his debut in 2019, 83 different players have caught at least 1,000 innings. On a per-inning basis, Zavala ranks 15th according to Statcast’s Fielding Run Values and ninth according to FanGraphs’ Defensive Runs Above Average.
Now for the bad stuff. Zavala has a career 70 wRC+, which means that he’s been 30% below the league average as a hitter. That’s awfully low, even for a catcher, as catchers ran a combined 91 wRC+ last season. However, Zavala has also never really played for an organization known for helping hitters become their best selves. He came up with the White Sox, with whom he played in parts of four seasons, played seven games with the Diamondbacks in 2023 after the team picked him up on waivers, then got sent to Seattle in the Eugenio Suárez trade before the 2024 season. Zavala is no longer young, and he runs gargantuan chase, whiff, and strikeout rates. He’s almost certainly never going to be a good hitter, but getting him into an organization that has had real success grooming hitters certainly won’t hurt. And whether or not he starts hitting, the glove will make him a valuable safety valve for the big club while helping with the development of younger pitchers in triple-A.
Nate Eaton is a 27-year-old who has until now spent his entire career with the Royals. He’s likely to serve a 27th-man role, filling in as a utility player when someone gets hurt. Eaton played third base and all three outfield roles during his 72 career games with the Royals, as well as some second base and shortstop in the minors. That versatility helps, but it’s not going to erase the fact that he has a career 51 wRC+. He spent the entire 2023 season at triple-A Omaha. His raw numbers .738 OPS looks nice, but when you account for the friendly hitting environment of the International League, that only translates to a wRC+ of 87. In all, Eaton should be a serviceable fill-in, and having that kind of depth can help keep a contending team afloat during a rough injury spell. Eaton also has excellent speed to go with quite possible the strongest arm of any position player in baseball. He pitched one delightful inning with the Royals during the 2023 season, and I wrote about it here. Eaton is a perfectly reasonable depth move, but we should all be rooting for the Red Sox to try to turn them into their next great pitching prospect.
