Baseball writer Joel Reuter has named Arizona Diamondbacks first baseman Tyler Locklear as a potential breakout candidate for the 2026 season. Locklear, who was acquired from the Seattle Mariners in a trade, is recovering from offseason elbow and shoulder surgeries and is expected to return to the team in mid-May. Though he struggled in his initial major league stint, Locklear put up impressive numbers in Triple-A last year, hitting .316 with 19 home runs. However, he will have to unseat veteran Carlos Santana, a strong defensive first baseman, to earn regular playing time.

Why it matters

Locklear's potential breakout could provide a boost to the Diamondbacks' lineup if he is able to translate his minor league success to the majors. As the team looks to improve on a disappointing 2025 season, finding young, cost-controlled talent like Locklear will be crucial.

The details

Locklear, 25, was acquired by the Diamondbacks in a trade with the Seattle Mariners. He struggled in his initial major league stint in 2025, posting a .532 OPS in 165 plate appearances. However, he excelled at the Triple-A level, hitting .316/.401/.542 with 19 home runs and 82 RBIs in 98 games. The Diamondbacks are hoping Locklear can build on that success, but he will have to unseat veteran Carlos Santana, a strong defensive first baseman, to earn regular playing time.

  • Locklear is expected to return from his offseason surgeries in mid-May 2026.

What they’re saying

“The immediate returns were not great after Locklear was acquired from the Mariners in the Eugenio Suárez trade. He also underwent elbow and shoulder surgery in October that will sideline him to start the year, but he still has a chance to claim a regular role once he returns.”

What’s next

The judge in the case will decide on Tuesday whether or not to allow Walker Reed Quinn out on bail.

The takeaway

This case highlights growing concerns in the community about repeat offenders released on bail, raising questions about bail reform, public safety on SF streets, and if any special laws to govern autonomous vehicles in residential and commercial areas.
