Arizona Diamondbacks manager Torey Lovullo stated on Tuesday that All-Star second baseman Ketel Marte has returned to Phoenix to undergo medical testing on his left knee. Lovullo expressed hope that Marte will be able to play again during the 2026 season.

The announcement follows Marte's departure from the team during their current road schedule. Lovullo noted that he was informed of the player's return to Phoenix by others and indicated there had been a lack of direct communication between himself and Marte regarding the travel.

Details regarding the specific nature of the knee injury or the results of the tests were not immediately available. The team has not yet provided a definitive timeline for Marte's return to the active roster, pending further evaluation by medical staff in Phoenix.

For fans and season ticket holders, the availability of a marquee player can influence the experience of attending games and the perceived competitiveness of the franchise. While the source does not detail specific contract figures or insurance implications, the long-term health of an All-Star athlete represents a significant asset for the multi-million dollar organization. The team must now balance the immediate need for Marte's production with the necessity of preventing further injury to his left knee, which could impact his availability for future seasons.

What happens next depends on the medical findings from the tests conducted in Phoenix. The Diamondbacks have not yet announced whether Marte will be placed on the injured list or if he might rejoin the team during their current road trip. Further updates are expected once the team's medical staff completes their evaluation and communicates the findings to Lovullo and the front office. The 2026 MLB season is currently ongoing, with no specific return date reported for Marte as of Tuesday.
