Fister apparently received multiple major-league contract offers this offseason, but the 35-year-old decided to call it quits in order to spend more time with the family. Across parts of 10 big-league seasons, Fister posted a career 3.72 ERA.

Fister made just 12 starts for the Rangers in 2018 due to injuries, posting a 4.50 ERA, 1.39 WHIP and 5.5 K/9 over those outings. While the veteran right-hander is expected to be healthy by spring training, he has now dealt with injuries in three of the last four seasons, posting a combined 4.56 ERA and 1.41 WHIP over that stretch.

Fister, who has been sidelined since June 10 with a strained right knee, was recently shut down after it was determined that he would be unlikely to pitch again this season. He'll continue rehabbing at home as he looks to get back to full health ahead of spring training next year. The 34-year-old posted a 4.50 ERA across 12 starts (66 inning) with the Rangers before injuring himself.

The extent of the strained right knee Fister suffered during his June 8 outing still isn't fully known, but the Rangers evidently determined that the injury was serious enough to sideline him for at least two months. In addition to depleting Texas' already porous rotation, Fister's injury likely closes the door on the Rangers selling him to a contending club at the July 31 trade deadline. With Fister joining Martin Perez (elbow) on the 60-day DL, newly promoted starters Yohander Mendez and Yovani Gallardo should both have the opportunity to make multiple turns through the rotation for the big club.
