Earlier this month at the winter meetings, Red Sox Chief Baseball Officer Craig Breslow hinted that the team aimed to boost its lineup with more power. Meanwhile, rumors linked Boston to free-agent slugger Pete Alonso, and reports indicated that Red Sox officials had reached out to him before he ultimately signed a five-year, $155 million deal with the Orioles.
When Alonso chose Baltimore—reportedly rejecting a shorter, less lucrative offer from Boston—the Red Sox wasted little time addressing their first base needs. Within two weeks, Boston traded three pitchers, including right-hander Hunter Dobbins, to the Cardinals to acquire first baseman and designated hitter Willson Contreras.
Though Contreras doesn’t possess Alonso’s power, the 33-year-old has maintained a 123 OPS+ or higher over the past four seasons. As a right-handed batter, he brings balance to the predominantly left-handed Red Sox lineup by adding a reliable offensive presence along the middle of the field. Defensively, Contreras transitioned to playing first base full-time this year without catching an inning, earning high marks with six outs above average, ranking him third among MLB first basemen.
Looking ahead, Contreras fills a key role for Boston, especially while Triston Casas continues recovering from a torn patella tendon. Adding Contreras allows Boston to delay Casas’ return from Triple-A and potentially split time between DH and first base upon his comeback. Meanwhile, Masanao Yoshida, a left-handed player from Fukui, Japan, faces uncertainty due to limited roster spots and a crowded outfield.
The Red Sox are also pursuing additional high-profile free agents, aiming to re-sign Alex Bregman or possibly make a big commitment to Bo Bichette at second base. Contreras marks the first major move to strengthen the lineup, with more acquisitions anticipated to finalize the roster.
For the Cardinals, newly appointed baseball operations head Chaim Bloom has focused on rebuilding by trading veterans like Sonny Gray and Contreras to emphasize player development. Acquiring young pitchers such as Hunter Dobbins fits this vision. Dobbins, who suffered an ACL tear last season, aims to earn a spot in the Cardinals’ starting rotation after recovering.
The Cardinals’ strategy involves clearing payroll and bringing in young arms to support a revamped pitching development program, aligning with their rebuilding plans for the offseason.
In the broader trade market, Contreras’ move is expected to trigger more activity this winter, especially surrounding Cardinals players Nolan Arenado and Brendan Donovan. The Cardinals are considering trading Arenado despite his no-trade clause, to give more playing time to emerging prospects, though Arenado’s declining power complicates this.
Other potential trade candidates include Diamondbacks’ second baseman Ketel Marte, Brewers’ right-hander Freddy Peralta, Tigers’ lefty Tarik Skubal, Nationals’ left-hander Mackenzie Gore, and Red Sox outfielder Jalen Duran. With plenty of offseason remaining, fans should watch for several possible trades before the season begins.
Fan Take: The Red Sox’s acquisition of Contreras signals a tactical effort to balance and bolster their lineup, making them a more formidable contender in the competitive American League East. For baseball fans, this move, alongside the Cardinals’ rebuilding efforts and an active trade market, promises exciting developments and a dynamic shift in team strategies heading into the new season.
