The Diamondbacks are no stranger to dealing from their perennial outfield depth, and GM Mike Hazen tells Nick Piecoro of the Arizona Republic that his stock of center fielders is again drawing interest. Hazen wouldn’t rule out a trade eventually coming together. It doesn’t sound as though Arizona is actively shopping any of its outfield options but rather listening to fairly robust interest, given the lack of center field options in free agency and elsewhere on the trade market. Diamondbacks fans, in particular, will want to check out Piecoro’s piece for a full slate of quotes and insight from Hazen.
The Snakes have Corbin Carroll, Alek Thomas and Jake McCarthy lined up as their likely outfield heading into the 2025 season, with Lourdes Gurriel Jr. mixing into left field as well. There’ll likely be some rotation of that bunch through the outfield and DH spots throughout the season. (Gurriel, it should be noted, is not a center fielder and is not seemingly among the players most heavily inquired about at this time.)
Of the D-backs’ trio of center field-capable outfielders, only Thomas and McCarthy stand as feasible trade candidates. Carroll, the 2023 NL Rookie of the Year, had a slow start in 2024 but bounced back to form as the season went on, slashing .256/.348/.522 (136 wRC+) over his final 425 plate appearances. He signed an eight-year, $111MM extension after a brief but excellent 32-game cup of coffee late in the 2022 season. He’s a cornerstone player in Arizona. Other clubs have probably inquired all the same, but Carroll is staying put.
Thomas and McCarthy, however, are at least a bit more plausible as trade candidates. The former ranked as one of the game’s top prospects for years but has yet to solidify himself as a viable everyday player in the majors. He’s a plus defender and runner when healthy but has mustered only a .226/.271/.359 batting line in 916 trips to the plate in the majors.
Thomas, 24, doesn’t strike out at an alarming clip (19.3%) but also ranks third among 251 big league hitters (min. 900 plate appearances) with a 57.2% ground-ball rate dating back to 2022. That penchant for grounders has undercut what scouting reports tabbed as above-average raw power. Thomas did pop 18 homers between Double-A and Triple-A a couple seasons back, but he has only 20 homers in his 916 big league plate appearances. Without elevating the ball more regularly, he’s unlikely to hit for much power in the majors. That said, he did make plenty of hard contact this past season (91.6 mph average exit velocity, 48.6% hard-hit rate). Even if much of that happens on the ground, a player with Thomas’ speed should see a far better average on balls in play than both the .200 he posted in 2024 and the .260 he’s notched in his career. There’s plenty to like about Thomas, and there are surely teams in need of a center fielder who are hoping they can buy low.
McCarthy, 27, is another solid defender — perhaps not quite to the extent of a healthy Thomas — who turned in a sharp .285/.349/.400 batting line in 2024. He smacked eight homers, swiped 25 bags (in 31 tries) and showed very strong contact skills (15.8% strikeout rate). He doesn’t have much power but also doesn’t possess glaring platoon splits. McCarthy doesn’t walk as much as one would prefer from a prototypical leadoff hitter (6.3% in 2024, 7.1% career), but he makes enough contact and runs well enough to profile as a table-setter who can handle all three outfield spots.
Both Thomas and McCarthy have one minor league option remaining and are controllable for another four seasons, which only adds to their appeal for win-now and rebuilding clubs alike. The Royals, Phillies, Pirates, Reds, Mets and Yankees are just some of the teams that could be in the market for outfield help this winter (though some of those obviously depend on the outcome of more pressing free agent pursuits).
As notably, Hazen indicated that any trades from his big league roster would be made with an eye toward improving another area of the MLB squad. The D-backs could lose Christian Walker to free agency, for instance, leaving a potential void at first base. Hazen has already publicly indicated that he hopes to add another high-leverage reliever/closer, though Piecoro specifically calls out the fact that the D-backs aren’t likely to move multiple years of a controllable outfielder in a straight-up swap for a reliever.
Fans may speculate on the potential to effectively purchase someone like Thomas or McCarthy by taking on some or even all of the remaining $22.5MM on Jordan Montgomery’s contract. That seems overwhelmingly unlikely. Four years of either Thomas or McCarthy would surely be valued at more than the remaining $22.5MM on that contract, and even Montgomery himself would probably still command several million dollars on a bounceback deal in free agency. Taking on his contract probably amounts to somewhere in the vicinity of $15MM in underwater money, and that sum isn’t nearly enough to persuade a team to part with a controllable big league outfielder.
