MLB Stars off to a Slow Start in 2026: Patience or Panic?

Several MLB stars are underperforming early in the 2026 season, raising concerns about their long-term prospects.

Some players, like Ketel Marte and Jesús Luzardo, show promising underlying metrics suggesting a potential turnaround.

Others, such as Rafael Devers and Luis Castillo, exhibit alarming trends that warrant greater concern.

The performance of players like Alec Bohm and Victor Scott II has led to discussions about potential replacements.

Rafael Devers (Giants): Devers is experiencing one of the worst stretches of his career, with a significant drop in barrel rate and walk rate. His struggles against fastballs are particularly concerning. Is this a sign of decline, or can he adjust and return to form?

Jackson Merrill (Padres): After a promising 2024 season, Merrill's whiff and strikeout rates are rising. While he has shown flashes of potential, his consistency remains a concern. Can he regain his previous form?

Luis Castillo (Mariners): Castillo's key performance metrics have regressed, contributing to a high ERA. At 33, with a history of heavy workloads, his future performance is uncertain. Will he be able to turn things around, or is this the beginning of a decline?

Alec Bohm (Phillies): Bohm's offensive numbers have declined significantly in his contract year. With limited minor league depth, the Phillies face a challenge in finding a suitable replacement. Can Bohm improve his performance and secure his future with the team?

Ketel Marte (Diamondbacks): Despite a slow start, Marte's underlying Statcast metrics remain strong, suggesting that he may be due for positive regression. Will his luck change, leading to improved results?

Victor Scott II (Cardinals): While Scott remains a valuable asset on the bases and in center field, his offensive struggles may lead to his demotion once Lars Nootbaar returns. Can he improve his hitting and maintain his role in the lineup?

Logan Gilbert (Mariners): Gilbert's ERA is uncharacteristically high, raising concerns about his performance. Can he return to his previous form and contribute to the Mariners' success?

Jesús Luzardo (Phillies): Despite a high ERA, Luzardo's ERA-adjacent metrics look promising, suggesting that he has been the victim of bad luck. Will his performance improve as the season progresses?

Cole Ragans (Royals): Ragans has struggled with command, but his underlying stuff remains impressive. With the Royals' track record of developing pitchers, there is optimism that he can turn things around. Will he be able to harness his potential and become a key member of the rotation?
