The Boston Red Sox face a tough challenge at first base. With Triston Casas sidelined for the rest of the season due to a severe knee injury, the team must act fast to fill a crucial lineup spot. As rumors swirl, many experts are now linking Anthony Rizzo to Boston as a possible replacement. Let's explore the current situation, Rizzo's potential fit, and what the Red Sox’ options are moving forward.

Triston Casas' Injury Creates a Void

On May 4, 2025, news broke that Triston Casas had suffered a ruptured patellar tendon in his left knee. This season-ending injury left the Red Sox short-handed at a key defensive and offensive position. As reported by ESPN, Casas had just 29 games under his belt this year. While his stats were not ideal, his presence on the field was significant for Boston's morale and infield stability.

The Red Sox now face difficult decisions on whether to patch the void internally, pursue a trade, or seek a veteran free agent.

Anthony Rizzo: A Proven Veteran Available

With first base talent in short supply, Anthony Rizzo stands out as an intriguing candidate. Recently linked to the Red Sox by prominent MLB insider Ken Rosenthal, Rizzo’s name has started to appear often in connection with Boston’s first base opening. As detailed by Yahoo Sports, Rizzo, the former Cubs and Yankees stalwart, is currently a free agent. His reputation for solid defense and veteran leadership could be a perfect match for Boston’s needs.

Though Rizzo’s 2024 season with the New York Yankees saw a dip in productivity, he still hit eight home runs over 92 games. Age and a slower recovery from past injuries may be factors, but his experience is hard to match. In addition, his left-handed bat could offer balance to the Red Sox lineup.

Exploring Internal and External Options

Boston's current plan involves a mix of internal options like Romy Gonzalez and Abraham Toro, but there is skepticism about their ability to hold down the position all season. As noted in the analysis from MLB Trade Rumors, in-house candidates have limited experience and questionable offensive upside. The idea of acquiring a stopgap like Mike Ford or Dominic Smith has also been floated, but such moves carry risk and may not provide the impact Boston needs.

Meanwhile, the Red Sox front office remains open to creative solutions. Shifting a player like Rafael Devers to first base is another possibility, yet the risks involved in asking someone to learn a new position mid-season are clear.

Will Rizzo Choose Boston?

The biggest question is whether Anthony Rizzo is ready to return and if Boston is willing to make the financial commitment. According to Ken Rosenthal, Rizzo’s name will stay in the mix as the Red Sox evaluate all options. Ultimately, the decision may hinge on Rizzo’s own readiness and the team's urgency to make a playoff push in a tight AL East race.

Conclusion

With Triston Casas out, the Red Sox need to make a pivotal choice about first base. Signing Anthony Rizzo could provide much-needed stability and leadership, while also keeping Boston in contention.
