The Chicago Cubs activate right-hander Jameson Taillon and make a corresponding roster move involving reliever Phil Maton. On Monday, the Cubs place Maton back on the 15-day injured list due to right knee tendinitis. At the same time, they activate Taillon, who is scheduled to start the opener of a three-game series against the Detroit Tigers. The moves also come as Chicago adjusts its pitching staff after recent roster changes. According to reports, the Cubs added right-hander Aaron Civale to their 26-man roster two days after acquiring Taillon in a trade from the Oakland Athletics. With these transactions, the Cubs align their active roster and injured list ahead of the series in Detroit, while continuing to manage Maton’s knee issue. The reports describe the IL placement as specific to tendinitis and do not provide additional details on timetable beyond the standard 15-day designation.
