DENVER -- The Colorado Rockies designated starter Michael Lorenzen for assignment Monday in a season in which the right-hander has gone 3-11 with a 7.08 ERA.
Lorenzen hasn't notched a win since June 27.
The Rockies signed the 34-year-old Lorenzen to a one-year deal in January. He was coming off a season when he struck out a career-high 127 in 141 2/3 innings for the Kansas City Royals.
"I love Mike. We developed a really good relationship," manager Warren Schaeffer said Monday before a three-game series against the NL West-leading Los Angeles Dodgers. "It's just time."
Righty Tanner Gordon will fill Lorenzen's spot in the rotation. Gordon has appeared in 17 games this season, including five starts, and has a 5.55 ERA.
"TG's been awesome," Schaeffer said. "Just keep doing what he's doing."
All-Star catcher Hunter Goodman was out of the lineup for a fourth game due to inflammation in his left shoulder.
"Still day-to-day," Schaeffer said. "We'll re-evaluate tomorrow."
To take Lorenzen's place on the roster, Colorado recalled righty TJ Shook from Triple-A Albuquerque. Shook has made four appearances with the Rockies this season, posting a 9.53 ERA in 5 2/3 innings. He has 11 saves for the Isotopes this season.
He's open to any sort of role.
"I've been told I've been a Swiss Army knife in the past. So whether that's long relief or short, closing, starting, I've started a lot of games," Shook said Monday. "Honestly, it helps me stay on my toes. I kind of come in with the same mindset -- just go out there and pitch, throw up some zeros and get ahead of guys."
Shook, 28, was taken in the Rule 5 draft from the New York Mets last offseason.
"Shooky is in a position where he's up and down right now," Schaeffer said. "Those guys need to do whatever you ask them to do. That's their role. He accepts that with vigor."
