12:34pm: Baker has already passed his physical, and the deal will be announced later today, tweets Greg Johns of MLB.com.
12:17pm: The Mariners have agreed to terms with right-hander Scott Baker on a minor league deal with an invitation to Spring Training, according to Chris Cotillo of MLB Daily Dish. Baker, who is represented by Octagon, will earn $1MM if he makes the team and can earn up to $3.25MM more via incentives, according to Cotillo (Twitter links).
The 32-year-old Baker underwent Tommy John surgery prior to the 2012 season -- his walk year with the Twins. He inked a one-year, $5.5MM contract with the Cubs last offseason, but persistent setbacks in his recovery limited him to three starts late in the season.
Baker's last significant big league action came in 2011, and it was also the best work of his career. In 134 innings for the Twins that season, the former second-round pick posted a 3.14 ERA with 8.2 K/9 and 2.1 BB/9. Strong command and K/BB numbers have been typical of Baker throughout his career, as evidenced by his lifetime 3.4 K:BB ratio. Baker's skill-set seems to be fitting of Safeco Field; the extreme fly-ball pitcher has just a 34 percent ground-ball rate for his career.
Should Baker make the rotation out of Spring Training, he'll slot in behind aces Felix Hernandez and Hisashi Iwakuma. Top prospect Taijuan Walker and right-hander Erasmo Ramirez are also candidates for the rotation, and the Mariners have been said to be on the lookout for a veteran starter to add to the mix as well (presumably, Baker is not that arm).
