Zimmermann is apparently feeling no pain during his physical therapy this offseason, but he has been receiving scheduled neck injections to help combat the pain that plagued him at times during the 2016 season. The 30-year-old is coming off a disappointing campaign in which he posted a 4.87 ERA over 105.1 innings, but figures to be a key piece in the Tigers' rotation this year.
Guthrie's last major league appearance came with the Royals during their 2015 World Series campaign. He spent the 2016 season with the Marlins' and Padres' Triple-A affiliates, posting a cumulative 7.17 ERA over 86.2 innings. At 37 years old, it's safe to assume that Guthrie's MLB career has likely come to an end.
Cole was diagnosed with elbow inflammation last August and was eventually shut down for the season. It appears that his recovery is going well and that he should be good to go when pitchers and catchers report to spring training in February.
Hill will turn 37 years old before next season begins, but the Dodgers are confident he has a few good years left in him and decided to extend what was a brief stint with the club at the end of last season. It remains to be seen exactly where Hill will slot into what figures to be a deep Dodgers rotation in 2017, but -- if healthy -- he is seemingly the favorite to head into the year as the No. 2 starter behind ace Clayton Kershaw.
The extra work before spring training may do Stroman some good. After missing most of 2015 recovering from ACL surgery, the righty struggled to knock off the rust early in 2016. Prior to the All-Star break, he posted a 4.89 ERA while managing 6.4 K/9 over 18 starts. Following the Midsummer Classic, Stroman dished up a 3.68 ERA and an 8.5 K/9. The WBC will give the 25-year-old an opportunity to enter 2017 well-oiled and ready to go.
The rumored deal would be for three years and $40M, a nice lift from the $6M, one-year deal he had for the 2016 season. Hill will turn 37 before the start of the 2017 season. His numbers were even better after being traded to the Dodgers, sporting a 1.83 ERA and 0.79 WHIP over six starts.
Lee was acquired by the Mariners in a trade with the Dodgers last June and figured to offer rotation depth while trying to find the stuff that made him a first-rounder and top prospect in the past. He did not accomplish the latter. The 25-year-old yielded a 7.39 ERA in 14 starts with Triple-A Tacoma and didn't see a major league inning with Seattle despite being on the 40-man roster in September.
This was a given, as Johnson underwent Tommy John surgery in October and is set to miss the entire 2017 campaign. Johnson was hit hard in six starts between Chicago and San Diego last season, giving a whopping 14 home runs in just 31.1 innings.
Locke was designated for assignment on Tuesday, so the non-tendering is mostly a procedural move as Locke seeks out another team. The 29-year-old is now four seasons removed from his All-Star 2013 season, which was probably thanks to a good deal of luck judging from his 4.03 FIP that year, so he might need to make the full transition to reliever if he wants to stick in the majors going forward.
Non-tendering Ross is a shocker from the Padres, who went from starting him on Opening Day to releasing him to free agency in the span of 2016. Between 2013 and 2015, Ross threw an average of 172 innings with a 3.07 ERA and 9.2 strikeouts per nine innings, but the shoulder woes that cost him nearly his entire 2016 season apparently made him not worth the $9 million price tag approximated by A.J. Cassavell of MLB.com. Ross underwent thoracic outlet syndrome surgery in October and is still recovering, but he is nearly certain to be picked up by a team needing rotation depth and accepting of his injury risk.
