In a move designed to balance veteran fatigue with a spark of unpredictability, the San Diego Padres are shifting one of the game’s most electric athletes back toward the infield. Fernando Tatis Jr., the Platinum Glove right fielder, is set to make his first MLB start at second base Saturday night against the Colorado Rockies.
The decision comes as part of a broader strategy by manager Craig Stammen to rotate rest days for the team’s core veteran position players. With shortstop Xander Bogaerts taking a scheduled day off, the Padres are rearranging their defensive alignment: Jake Cronenworth will slide over to shortstop—a role he has filled frequently since last season—although Nick Castellanos will take over in right field.
While the move serves a practical purpose in the lineup, it also represents a calculated gamble on the psychological state of Tatis. The 27-year-old is currently navigating the most difficult offensive stretch of his professional career, posting a .519 OPS over his last 14 games. Despite the low production, the underlying metrics suggest a streak of poor luck, with several hard-hit balls failing to find open grass.
Stammen, a former teammate of Tatis, believes a change in scenery—even by just a few dozen feet on the diamond—could be the catalyst for a breakout. “Maybe him concentrating on playing second base unlocks him at the plate, he stops thinking so much about it and just uses his natural talent to take over,” Stammen said. He noted that Tatis has shown visible frustration, particularly after hitting two balls over 100 mph on Friday night that did not result in hits.
A Return to Infield Roots
Though Tatis has become a fixture in the outfield, his athletic pedigree was forged in the dirt. He began his Major League journey as a shortstop, a position he has not occupied since his 2023 return following multiple arm surgeries and a suspension related to performance-enhancing drugs. His transition to right field was a permanent shift for the team’s structural stability, especially given the long-term contracts of Bogaerts and Cronenworth.
However, the move to second base is not an unplanned experiment. Tatis has a modest history at the position, including 10 starts early in his minor-league career and a brief late-game appearance in September 2023. To prepare for this specific audition, Tatis spent the last month drilling daily with infield coaches Ryan Goins and Nick Punto, supplementing the occasional ground balls he took during the previous season.
The idea of a return to the infield was floated by Stammen during the offseason, shortly after he took over as manager. Tatis admitted he initially viewed the suggestion as a joke. “I didn’t take it that serious,” Tatis said, laughing. “But here we are.”
The Defensive Calculus
For the Padres, the move is as much about versatility as it is about mental resets. Tatis is widely regarded as one of the most gifted athletes in Major League Baseball, earning both Gold Glove and Platinum Glove honors in 2023 and 2025. By proving Tatis can handle second base, Stammen gains a significant tactical advantage in late-game substitutions and roster management.
The organizational priority remains keeping the primary stars healthy. Because Bogaerts and Tatis are both under contract well into the next decade, the coaching staff is prioritizing “periodic rest” to avoid the late-season burnout common in the grueling MLB schedule. The decision to move Cronenworth to short rather than Tatis reflects Stammen’s comfort level with Cronenworth’s recent performance at that position.
Tatis himself has embraced the shift with a professional, low-pressure attitude. “I can play whatever,” Tatis said. “I’m just here to play baseball and be a good baseball player. Looking forward to the challenge and embracing it.”
Analyzing the Offensive Slump
The primary motivation for this shift is the “unlocking” of Tatis’s bat. A two-time Silver Slugger, Tatis is currently struggling to convert his power into results. The disparity between his exit velocity and his batting average has created a tension that Stammen hopes to alleviate by shifting his mental focus toward the complexities of playing second base.

The following table outlines the current defensive transition for Saturday’s game:
| Player | Standard Position | Saturday’s Assignment |
|---|---|---|
| Fernando Tatis Jr. | Right Field | Second Base |
| Jake Cronenworth | Second Base | Shortstop |
| Nick Castellanos | (Rotation/Bench) | Right Field |
| Xander Bogaerts | Shortstop | Rest Day |
Whether this move becomes a permanent part of the Padres’ tactical toolkit remains to be seen. Tatis will continue to be the team’s primary right fielder, but Saturday serves as the first official audition for a recurring role in the infield. Stammen remains optimistic about the outcome, noting that while perfection is never guaranteed, he is not worried about the capabilities of a player with Tatis’s range and instincts.
“Will he be perfect, like the best second baseman of all time? He might be, but you never know,” Stammen said. “We’ll see. But I’m not that worried about Fernando Tatis Jr. Playing second base.”
The Padres will continue their series against the Rockies, with the coaching staff monitoring Tatis’s defensive efficiency and his performance at the plate to determine if the “second base effect” yields the offensive resurgence they are seeking.
