Rockies Designate Michael Lorenzen After 3-11 Start with 7.08 ERA

The Colorado Rockies designated Michael Lorenzen for assignment on Monday and recalled righty TJ Shook from Triple-A Albuquerque.

The Colorado Rockies designated starting pitcher Michael Lorenzen for assignment on Monday, ending a tenure where the 34-year-old right-hander posted a 3-11 record and a 7.08 ERA. Lorenzen, who signed a one-year contract in January, has not recorded a victory since June 27. This roster move preceded a three-game home series at Coors Field against the National League West-leading Los Angeles Dodgers. Manager Warren Schaeffer confirmed the decision, noting that while a strong relationship had developed with the veteran, the club determined it was time to move in a different direction.

To fill the vacancy on the active roster, Colorado recalled right-handed pitcher TJ Shook from Triple-A Albuquerque. The 28-year-old Shook arrives with 11 saves recorded for the Isotopes this season. In his previous four appearances for the Rockies this year, he pitched 5 2/3 innings and struggled with a 9.53 ERA. Shook joined the organization via the New York Mets through the Rule 5 draft during the last offseason and has experience in various pitching capacities, including starting and closing.

Rotation Shift and Bullpen Versatility

Right-hander Tanner Gordon is slated to take over Lorenzen’s position in the starting rotation. Gordon has participated in 17 games for the Rockies this season, including five starts, and currently maintains a 5.55 ERA. Schaeffer praised Gordon’s recent contributions, urging the pitcher to maintain his current trajectory. The manager described Shook as a player in an "up and down" position who must remain prepared for any assignment the coaching staff requires.

Shook referred to himself as a "Swiss Army knife," citing his history in long relief, short relief, and starting roles. He emphasized a mindset focused on throwing strikes, getting ahead of hitters, and recording scoreless frames regardless of when he enters the game. His versatility is expected to provide flexibility for a pitching staff looking to stabilize its performance against division rivals.

Injury Updates and Historical Context

All-Star catcher Hunter Goodman remained sidelined for Monday’s lineup, marking his fourth consecutive game missed. Goodman is currently dealing with inflammation in his left shoulder. Schaeffer categorized the catcher’s status as day-to-day, with a formal re-evaluation scheduled for Tuesday. The absence of the All-Star creates a significant gap in the Rockies' batting order during the series opener against Los Angeles.

Lorenzen’s departure follows a 2025 campaign with the Kansas City Royals where he established a career-high mark of 127 strikeouts over 141 2/3 innings. Despite that previous success, his production dipped significantly in Colorado, leading to the Monday afternoon transaction. The Rockies now look to their younger arms to eat innings as the season progresses through the late summer months.

Roster Management and Rule 5 Impact

The decision to lean on Shook highlights the team's utilization of Rule 5 acquisitions to fill immediate gaps. Schaeffer noted that players in Shook's position are expected to accept their fluctuating roles with vigor. As the Rockies navigate the three-game set against the Dodgers, the performance of the revamped pitching staff will be under scrutiny. The team continues to monitor Goodman's shoulder recovery to determine if a stint on the injured list will be necessary or if he can return to the field later in the week.
