The Chicago Cubs made a significant roster change by designating pitcher Jameson Taillon for assignment. His struggles this season led to this decision. Taillon acknowledged his performance was not meeting expectations. His 5.92 ERA with 25 home runs allowed in 76 innings underscored the issues.
Taillon himself admitted, “The results speak for themselves.” He recognized the pressure to improve, emphasizing he did not want to harm the team’s playoff chances. Yet, the Cubs could not wait for improvements and pulled him from the rotation. This move came before their series opener against the St. Louis Cardinals.
In Taillon’s place, Andrew Wantz was called up from Triple-A Iowa. Taillon’s Cubs career ended with a 4.21 ERA over 96 games, 95 of which were starts. Manager Craig Counsell explained the decision was difficult, mentioning Taillon’s positive impact on the team’s culture. However, the team needed better performance at this point in the season.
Statistics paint a stark picture. Taillon’s -1.1 fWAR and 6.74 FIP were the worst among MLB pitchers with at least 60 innings this year. While sidelined with a hamstring strain, the hope was for him to improve command and reduce home runs allowed. Unfortunately, improvements did not materialize.
Javier Assad will take over Taillon’s spot in the rotation. Assad’s next start is scheduled against the New York Yankees at Wrigley Field. The Cubs also look forward to Edward Cabrera’s return from a hamstring strain. Cabrera will start a rehab assignment in Triple-A, expecting to need three starts before rejoining the team.
Within the Cubs’ clubhouse, Taillon’s departure resonated deeply. Counsell appreciated Taillon’s role as a mentor, describing him as humble and helpful. Teammate Dansby Swanson referred to Taillon as one of his closest friends in baseball, saying, “Definitely on my Mount Rushmore of teammates.”
Matthew Boyd, another Cubs pitcher, expressed his respect for Taillon’s consistent presence and positive attitude. Boyd emphasized Taillon’s strength in managing his demeanor regardless of his performance. Ian Happ echoed these sentiments, highlighting the ten-year bond shared with Taillon and the difficulty in losing such a valuable teammate.
Despite this challenging season, Taillon had shown his potential in previous years. He played a crucial role in the Cubs’ successful runs, particularly in the 2025 season. However, this year lacked those pivotal moments necessary to secure his position.
The Cubs had not expected Taillon’s four-year contract to conclude in this manner. Pitching coach Tommy Hottovy, along with others, remain optimistic that Taillon has more to offer in his baseball career. The challenge lies in unraveling and correcting the underlying issues in his pitching mechanics.
Boyd concluded with a poignant reminder: “Performance is the measure we all face, but knowing that doesn’t soften the impact.” The Cubs now move forward, aiming to bolster their pitching lineup for the remainder of the season.
