This comes as no surprise to anyone, as the left-hander turned in his best statistical season last year. He'll face a rebuilding Brewers squad to open up the 2016 campaign.
Montas made his MLB debut in 2015 with the White Sox as both a starter and reliever and was expected to have a shot at the Dodgers' 25-man roster out of spring training. Given his potential as both a starter and reliever, his role in 2016 could be dictated by need when he recovers. This shouldn't affect the 22-year-old's future potential too much, but it's an ailment that could nag even after he returns.
Nolin was one of the pieces the A's received in the Josh Donaldson trade and was thought to have a shot at the 2016 A's rotation. The A's needed to clear a spot on the 40-man roster with the acquisition of Khris Davis and Nolin was the one they chose to designate. Nolin struggled with a groin injury for much of 2015 and his velocity was noticeably down when he was able to return late in the year. It seems likely that Nolin will garner some interest from other teams around the league.
Satterwhite produced a 4.38 ERA and 1.43 WHIP while boasting an impressive 8.88 K/9 over 72 innings of work for Triple-A Las Vegas in 2015. The 29-year-old will begin 2016 in the minor leagues.
Snodgress posted a 5.19 ERA in 8.2 innings pitched at the Double-A level and an 11.16 ERA in 25.0 innings pitched at the Triple-A level in 2015. He has been fairly mediocre in his minor-league career and struggled mightily in his brief callup with the White Sox in 2014. The 26-year-old will have to improve drastically if he wants a shot at making the big-league team in 2016.
One of the top prospects in the Rockies organization after being acquired in the Troy Tulowitzki deal, Hoffman pitched well at the Double-A level. Although he shows promise, he'll likely head back to the minors after spring training to pitch more against upper-level hitters.
Castro pitched well with Triple-A Albuquerque last season, but he failed to perform well once he received a promotion to the majors. It will be tough for Castro to crack the Rockies bullpen unless significant improvements are made.
The 2014 first-round draft pick hasn't pitched above High-A in his career, but the Rockies like him enough to bring him to big league camp during spring training. Despite this, he'll likely head back to the minors for seasoning after spring training concludes.
Flande spent a lot of 2015 pitching in the majors with the Rockies, but only produced a 4.74 ERA, which led the Rockies to non-tender him in December. He'll return to the Rockies for 2016, although the left-hander will likely serve as organizational depth unless he can improve a fair amount during the spring.
Luebke had his 2016 option declined by the Padres after two Tommy John surgeries since 2012 and another elbow injury in July derailed his tenure with San Diego. The left-hander pitched well in the majors from 2010-2012 with a 3.25 ERA, though, so he could get some looks for the fifth rotation spot, although it's probably more likely that he'll begin 2016 in the minor leagues.
