West recorded two appearances with the Dodgers during the summer, but the 27-year-old has mainly pitched in the minors throughout his seven-year career. He'll likely provide some organizational depth for the Dodgers next season.
Ramirez appeared in 20 games between the Mariners and the Diamondbacks this season, recording a 5.32 ERA and 1.52 WHIP in 23.2 innings. The 27-year-old did pitch well in Triple-A last season (2.72 ERA in 43 innings) so he could earn a spot with the Reds during spring training, but he's unlikely to pitch in enough high-leverage innings to become fantasy relevant.
Roark and Joe Ross would replace Jordan Zimmermann and Doug Fister in the rotation as things stand, although GM Mike Rizzo could still bring in another starter through trade or free agency, and a big spring from a prospect like Lucas Giolito could create a job battle. Roark had a 2.85 ERA and 15 wins in 31 starts in 2014, so the Nats are comfortable with him taking a regular turn.
Chamberlain made appearances with the Tigers and Royals in 2015, recording a 4.88 ERA and 1.45 WHIP in 27.2 innings between the two clubs. Considering the Indians seemingly lack of depth in the bullpen, the 30-year-old has a decent to open with the team out of spring training, but it's unlikely Chamberlain will be placed in enough high-leverage pitching opportunities to make him fantasy relevant.
Collins torn the UCL early in spring training 2015 and underwent Tommy John surgery shortly thereafter. Although the 26-year-old southpaw missed the entire season and will likely miss a good portion of the upcoming campaign, he could factor into the Royals' bullpen, once he regains his health. In the wake of the signing, it was revealed that Collins inked a one-year, $1.475 million deal.
Johnson opened last season as the Braves' top setup man and eventually took over closing duties from Jason Grilli following the latter's season-ending Achilles injury. However, Johnson's stint as a closer lasted less than a month before he was shipped to the Dodgers at the trade deadline. In the end, he made 72 appearances between the two organizations, posting 10 saves to go with a 2-6 record, 4.45 ERA, 1.455 WHIP, and 50:20 K:BB in 66.2 innings. Expect Johnson to challenge for the Braves' setup role yet again.
Abad was a casualty of the team needing space on the 40-man roster, as he was designated for assignment earlier in the month, but the other 29 clubs apparently weren't interested in the left-hander. He spent the entire season in the majors in 2015 but could begin next year in the minors.
Clemens spent the season with four different minor league clubs but didn't enjoy much success at any stop, pitching to a 5.73 ERA with a .281 batting average against combined. He's had some experience in the majors in his career but will likely serve as bullpen depth in the Marlins' organization.
Mariot was designated for assignment by the Royals earlier in the month in order to clear room on the 40-man roster after spending the majority of the season with Triple-A Omaha. The righty has pitched just 28 innings in the big leagues in his career, but posted a 2.32 ERA and 72 strikeouts in 62 innings with Triple-A last season and could get a chance to work out of the Phillies' bullpen in 2016.
"If we can help him get back on track, he can help our team in a variety of roles," GM Neal Huntington said. The Pirates have spots available in both the rotation and bullpen, but Webster is out of minor league options, meaning he could be lost to waivers if he doesn't make the club out of spring training.
