In a separate roster move announced ahead of the Sunday game, the Mets optioned rookie right-hander Jack Weisenburger back to Triple-A Syracuse. Weisenburger, 28, had made his major league debut earlier in August, but the club decided to send him back to the minors as part of a broader roster shuffle. The Mets also recalled right-hander Chayce McDermott and infielder Eric Wagaman from Syracuse, and placed second baseman Jorge Polanco on the 10-day injured list with left ankle bursitis.
Weisenburger’s cup of coffee in the majors consisted of three relief appearances, totaling 4 1/3 innings. He posted a 2.08 ERA with four strikeouts but also issued two walks. While those numbers are solid for a first extended look at big-league hitters, they weren’t enough to secure a longer stay in the Mets’ bullpen as September call-ups approached.
Jack Weisenburger’s journey to the majors has been anything but traditional. Born John Edward Weisenburger on October 8, 1997, in Rockford, Michigan, he stands 6-foot-3 and weighs 220 pounds. He hails from a family with a strong athletic heritage; his grandfather and father both played football at the University of Michigan, with his grandfather earning a Rose Bowl win in 1948 and his father later playing football and baseball for the Wolverines in the mid-1970s.
Drafted by the Oakland Athletics in the 20th round of the 2019 draft (614th overall), Weisenburger navigated a long minor league path through Beloit, Stockton, and Lansing before advancing to Double-A Midland. He even spent time in winter ball with Naranjeros de Hermosillo in Mexico’s Pacific League. The major league opportunity didn’t come with the A’s, who released him in early 2025 after his stint with the RockHounds.
His path then took an unconventional turn. Weisenburger played for the independent Atlantic League’s Hagerstown Flying Boxcars in 2025, opened 2026 with El Aguila de Veracruz in the Mexican League, and was released by Veracruz in April. The Mets signed him to a minor league contract on May 2, assigning him to the Brooklyn Cyclones before quickly promoting him to Syracuse.
Before his big-league debut, Weisenburger’s performance at Syracuse this season was challenging. He went 7.22 ERA with a 1.57 WHIP and a 46/27 strikeout-to-walk ratio over 14 appearances (12 starts) spanning 52 2/3 innings. Those numbers suggested a waiting game for a call-up, but injuries and roster churn across the Mets’ organization opened a window for him to contribute at the highest level. He arrived on August 9 and delivered the type of multi-inning relief that teams often seek when bullpen depth is stretched.
From a broader perspective, Weisenburger’s stint with the Mets underscores the organization’s emphasis on depth and flexibility. The team entered the season hoping to build on recent postseason appearances, but injuries and inconsistent performances have left them scrambling to sustain competitiveness down the stretch. In that context, a 28-year-old rookie who can provide length out of the bullpen—even briefly—adds value to a pitching staff that has been tested by turnover.
Looking ahead, Weisenburger is a plausible candidate to return when rosters expand in September. His brief, productive exposure to major-league hitters adds a layer of credibility to his skill set, suggesting potential as a fringe bullpen option or as dependable depth at Triple-A. For a pitcher who had spent most of the year in the Mexican League just months earlier, earning a spot on the Mets’ radar represents a meaningful personal milestone and a reminder of the unpredictable paths players can take to reach the majors.
On the opposing side, the White Sox lineup featured a mix of established players and rising talents. The top of their order included Sam Antonacci and Munetaka Murakami, with Andrew Benintendi serving as a veteran presence in the designated hitter spot. Braden Montgomery and Tristan Peters were among the youngsters contributing across the middle of the lineup, while Colson Montgomery and Chase Meidroth provided middle-infield depth. Jake Rogers caught, and Tristan Peters patrolled center field, as Chicago looked to fine-tune its approach late in the season.
For the Mets, the current focus remains on building a sustainable bullpen and identifying additional depth for a potential late-season push. The series win over Chicago, coupled with the Weisenburger call-up and subsequent brief major-league appearance, demonstrates the organization’s willingness to explore unconventional avenues to supplement a pitching staff facing injuries and fatigue. While the immediate results may not alter the broader arc of a season that has been challenged by inconsistency, the experience gained by Weisenburger and the continued development of other farm-system arms could contribute to a more robust rotation and bullpen in the years to come.
As the Mets head into the final stretch of the campaign, every game offers a chance to fine-tune the roster, evaluate emerging talents, and prepare for the workload that comes with a late-season run. The Weisenburger arc, from Mexico to the majors, adds a human element to the ongoing quest for pitching depth and organizational resilience in a pennant race that is rarely predictable.
