D-Backs Trade Alek Thomas To Dodgers

While he hasn’t developed offensively, Thomas has a strong reputation with the glove. His sprint speed and defensive grades have dipped slightly since he suffered a left hamstring strain early in 2024, but he still rates as an above-average defender and baserunner.

The D-Backs have considered trades of both Thomas and Jake McCarthy for a few seasons. They’re now both gone to division rivals, as they shipped McCarthy to Colorado over the offseason. Waldschmidt and Jorge Barrosa are manning center field between Corbin Carroll and Lourdes Gurriel Jr.

Thomas still has a minor league option remaining, so he’ll begin his time in the L.A. organization in Triple-A. The Dodgers are operating without a true backup center fielder behind Andy Pages, but they can’t option Santiago Espinal or Miguel Rojas. Although fourth outfielder Alex Call is a better fit in a corner spot and has a couple options remaining, he’s hitting well in a limited role as a right-handed platoon player. The Dodgers should also get Kiké Hernández back from the injured list two weeks from now.

The Dodgers spend a couple million dollars to swap in Thomas for Siani as a fifth outfielder. In addition to the salary obligations, they’ll also pay just over $1.5MM in luxury tax commitments. That’s of little concern for the Dodgers, who can retain Thomas via arbitration for at least two more seasons. He needs to spend another 20 days on the MLB roster in 2026 to surpass four years of service time, which would keep him on track for free agency after the ’28 campaign. If he spends at least 20 days in the minors, he’ll be out of options next year.

Siani is also a speed and defense center fielder. He bounced around the league via waivers over the offseason, twice being claimed by the Dodgers. He has been on optional assignment all season, batting .225/.355/.303 without a home run while striking out 30 times in 107 plate appearances in Oklahoma City. He’s also in his final option year and will be traded or placed back on waivers within the next five days.

Requena is a 17-year-old who hasn’t played a professional game. Listed at 6’3″ and close to 230 pounds, he’s a right-handed hitter who signed as an amateur out of Venezuela in January. Ben Badler of Baseball America unsurprisingly wrote at the time that Requena is a corner outfielder whose profile is built on raw power and plus arm strength. He’ll likely make his professional debut in the Dominican Summer League this year.

MLBTR’s Steve Adams first reported that Thomas was being traded to the Dodgers. Fracys Romero confirmed that Requena was the return. Nick Piecoro of The Arizona Republic reported that the Dodgers were assuming Thomas’ salary, while Jack Harris of The California Post confirmed he’d be optioned to Triple-A. Image courtesy of Mark J.
