Thielbar's $6 million mutual option for 2027 was declined by the Cubs on Monday.
Thielbar had an up-and-down 2026 campaign, posting a 4.86 ERA and 60:18 K:BB over 50 regular-season innings. The left-hander will turn 40 in January, but he should be able to land a big-league contract if he wants to continue his career.

Thielbar is not on the Cubs' roster for their NL Wild Card Series against the Padres, Meghan Montemurro of the Chicago Tribune reports.
Thielbar carried a 60:18 K:BB over 50 regular-season innings, but he also had a 4.86 ERA and served up a whopping 11 home runs. The lefty could be under consideration for the NLDS roster, should the Cubs advance.

Thielbar (3-4) took the loss after allowing three runs (two earned) on two hits over one inning in Tuesday's 8-2 extra-innings loss to the Marlins.
Thielbar worked a scoreless 11th inning before returning for the 12th, but that's when things went south for the left-hander. Thielbar allowed the first batter he faced to drive home the inherited runner at second, and by the time the frame ended, the Marlins had built a lead they wouldn't relinquish. Thielbar's ERA rose to 4.99, and this mark his first outing allowing more than one earned run since Aug. 16.

Thielbar allowed two runs on three hits while retiring just one batter in relief during Friday's 6-4 win over the Royals.
After seven strong innings from new Chicago starter Kevin Gausman in which he allowed just two runs, Thielbar quickly ran into some trouble in the eighth. The lefty got the hook before Trent Thornton finished out the frame to earn a hold. Thielbar has been struggling recently with a 17.18 ERA across his last five appearances, which has pushed his overall ERA up to 5.30. With Thornton, Jacob Webb and Ryan Zeferjahn all seemingly ahead of him in the bullpen pecking order, and Daniel Palencia (elbow) expected back soon, Thielbar doesn't have much fantasy appeal at the moment.

Thielbar earned the save in Saturday's 5-2 win over the Yankees, allowing one hit in a scoreless ninth inning. He did not record a walk or a strikeout.
With Jacob Webb used in the eighth inning against the heart of the Yankees' order, Thielbar was called upon to protect a three-run lead in the ninth and worked around a leadoff single to earn his first save since April 21. The 39-year-old Thielbar owns a 3.97 ERA, 1.21 WHIP and 43:13 K:BB to go along with seven holds and three saves across 34 innings this season. He shouldn't be counted on as a reliable source of saves going forward with Daniel Palencia (elbow) nearing a rehab assignment.

Thielbar picked up his second hold Thursday after pitching one scoreless inning while allowing two walks and no hits with two strikeouts in a 7-2 win over Pittsburgh.
Thielbar was called upon in relief for the second straight day and registered another scoreless frame. The 39-year-old entered in the seventh inning, striking out Brandon Lowe and Oneil Cruz to maintain the 3-2 lead, though he made things interesting with a pair of walks. Thielbar has posted a 2.84 ERA, 1.34 WHIP and 15:8 K:BB with two saves and two holds in his 10th major league season.
