San Diego Padres Rotation Set for Major Changes Ahead of 2026
The San Diego Padres rotation is about to look drastically different heading into 2026. With Dylan Cease and Michael King set to hit free agency and uncertainty surrounding Yu Darvish’s future, the Padres desperately need frontline pitching to complement Nick Pivetta.
Enter Milwaukee Brewers ace Freddy Peralta, who just completed one of the best seasons of his career and finds himself at the center of trade speculation this offseason. Peralta is expected to finish in the top three in the NL Cy Young Award voting.
The Brewers have an $8 million team option on Peralta for next season that they will certainly pick up. However, after exercising that option, the Brewers are expected to mirror the approach they took two years ago with their then-ace Corbin Burnes and trade him.
Why Freddy Peralta is the Perfect Fit for San Diego
The Padres are staring down a rotation crisis that demands immediate attention. Beyond Pivetta—who emerged as a bona fide ace in 2025—the cupboard looks concerningly bare. Joe Musgrove is returning from Tommy John surgery with no guarantees, Darvish turns 40 next season amid persistent injury concerns, and Randy Vasquez remains unproven as anything more than a back-end starter.
San Diego’s upper farm system was significantly depleted at the trade deadline when GM A.J. Preller dealt multiple prospects to acquire Mason Miller and JP Sears.
Peralta represents the ideal solution to this problem. The 29-year-old right-hander is coming off the best year of his career, having really figured out how to use and mix his dominant arsenal.
“Fastball Freddy” held opposing batters to a .209 average against his four-seamer, .173 against his changeup, .183 against his curveball, and an impressive .157 against his slider. He finished the 2025 campaign with a 17-6 record, a 2.70 ERA, and 204 strikeouts across 176.2 innings, establishing himself as a true top-of-the-rotation ace.
What makes Peralta particularly attractive is his contract situation. At just $8 million for the 2026 season, he represents tremendous value compared to the rates free-agent starters will command this winter. That financial flexibility allows the Padres to allocate resources elsewhere while still landing an ace-caliber arm.
Though Peralta will hit free agency after 2026, one guaranteed year of elite production could be the difference between a World Series run and an early playoff exit for San Diego.
What the Brewers Need in Return
Milwaukee’s decision to explore trading Peralta stems from their organizational philosophy and roster construction. The Brewers have proven they won’t hesitate to trade controllable stars before losing them to free agency, having already dealt Corbin Burnes and Devin Williams in consecutive offseasons.
With Peralta set to become a free agent after 2026 and unlikely to re-sign with small-market Milwaukee, general manager Matt Arnold must maximize his trade value now.
The Brewers’ rotation picture for 2026 looks promising even without Peralta. They boast one of the deepest collections of young, controllable starting pitchers in baseball, including Jacob Misiorowski, Quinn Priester, Chad Patrick, Tobias Myers, Robert Gasser, and Logan Henderson—all under team control through 2030.
However, most of these arms lack extensive major league experience, creating a need for upper-level pitching depth that can step in if necessary.
Milwaukee’s farm system ranks among baseball’s elite, sitting at No. 4 according to MLB Pipeline’s latest rankings. Their top prospects are heavily concentrated in the infield, led by Jesus Made (MLB No. 5 overall prospect), Luis Pena (No. 16), and Cooper Pratt (No. 53).
While they have pitching depth in the lower minors, more advanced arms with major league upside could complement their young rotation.
The Perfect Trade Package
San Diego Padres receive:
- RHP Freddy Peralta
Milwaukee Brewers receive:
- RHP Humberto Cruz (Padres No. 3 prospect)
- LHP Kash Mayfield (Padres No. 4 prospect)
- RHP Miguel Mendez (Padres No. 5 prospect)
- RHP Isaiah Lowe (Padres No. 12 prospect)
This trade proposal gives both teams exactly what they need.
For San Diego, they land the ace starter their rotation desperately requires without surrendering their crown jewel prospects like catcher Ethan Salas or first-round pick Kruz Schoolcraft.
The Brewers receive an embarrassment of pitching riches aligning perfectly with their organizational timeline.
Humberto Cruz, just 18 years old, already touches 97 mph with his fastball and projects as a future frontline starter with an estimated 2029 MLB arrival.
Kash Mayfield, San Diego’s 2024 first-round pick, features elite offspeed offerings—including a devastating changeup—that could make him a future ace. At 6-foot-4, Mayfield combines premium stuff with plenty of projection left in his frame.
Miguel Mendez brings the most immediate value of the package. The 23-year-old right-hander just captured the Padres’ Minor League Player of the Year award after posting a 3.22 ERA with 118 strikeouts in 95 innings across three levels.
Mendez now sits 95-98 mph and touches triple digits with his fastball while pairing it with a tight upper-80s slider. He’s major league ready and could contribute to Milwaukee’s rotation as soon as 2026, providing the experience their young staff lacks.
Isaiah Lowe rounds out the package as a high-upside arm with more developmental runway. The 22-year-old provides Milwaukee with another lottery ticket who could develop into a mid-rotation starter.
This trade maximizes value for both organizations. The Padres get their ace without completely decimating their future, keeping Salas and Schoolcraft as cornerstones while maintaining some prospect depth.
The Brewers receive four legitimate pitching prospects who fit their competitive window, with Mendez providing immediate help and the others offering star potential down the road.
There will be plenty of interest in Peralta on the trade market, with the Red Sox, Orioles, Mets, Angels, Astros, Giants, and Tigers all likely to inquire. However, the Padres can offer the perfect combination of quality and quantity that Milwaukee needs.
This deal gets both teams closer to their ultimate goal: winning a World Series championship.
