The Arizona Diamondbacks are being tipped as a 2026 MLB threat thanks to a trio of star players - Ketel Marte, Corbin Carroll, and Geraldo Perdomo. According to projections, all three are expected to surpass the 4-WAR threshold, making the D-backs one of just three teams (along with the Dodgers and Mets) to have three position players reach that elite level.

Why it matters

The Diamondbacks have struggled in recent seasons, but the addition of Nolan Arenado and the continued development of their young core has fans excited for a potential resurgence. If Marte, Carroll, and Perdomo can live up to expectations, Arizona could emerge as a surprise contender in 2026.

The details

The Diamondbacks made a big splash this offseason by acquiring Nolan Arenado in a trade with the Cardinals, shoring up their lineup. They also re-signed ace Zac Gallen to a one-year deal, solidifying their starting rotation. With these key moves, the focus now turns to the trio of Marte, Carroll, and Perdomo, who are projected to be among the most productive position players in the league next season.

What they’re saying

“Ketel Marte will begin the 2026 season in Arizona. That keeps one of the league's top-of-the-order trios intact in Marte, Corbin Carroll, and Geraldo Perdomo. FanGraphs projects each player to clear the 4-WAR threshold in 2026; the D-backs are one of just three teams (along with the Los Angeles Dodgers and New York Mets) with three position players projected to accumulate at least 4.0 WAR.”

What’s next

The Diamondbacks will look to build on their offseason moves and see if their young core can lead them to a surprise playoff berth in 2026.

The takeaway

The Diamondbacks have assembled an impressive trio of young talent in Marte, Carroll, and Perdomo, and if they can all take the next step in 2026, Arizona could emerge as a dark horse contender in the National League.
