Brice saw the majors for the first time in his career with Miami in 2016, and gave up 12 runs (11 earned) over 15 appearances. He'll have a chance to earn a role in the Cincinnati bullpen this spring, but even if that doesn't work out, look for the right-hander to open the season in Triple-A. Brice has a fastball that can flirt with the upper-90s, but he'll need to get left-handers out consistently to be a mainstay at the major league level. Nine of his 11 earned runs in last year's stint came off the bats of lefties.
Castillo was marvelous for High-A Jupiter in 2016, posting a 2.26 ERA and 0.96 WHIP over 117.2 frames. The 24-year-old right-hander eventually earned a promotion to the Double-A level, where he is expected to start for Cincinnati in 2017. One of Miami's top-10 prospects, Castillo possess a fastball that consistently hits the upper-90s, but needs to work on the command of his secondary pitches before getting a chance in the majors.
Gomez racked up 37 saves last season before faltering in September and losing his job. Joaquin Benoit, Hector Neris and Edubray Ramos will also be in the mix for closing duties this spring, but it sounds like Gomez will get the nod for the job if he pitches well in camp.
The 35-year-old Boyer is coming off a season in which he allowed 80 hits with a mere 26 strikeouts in 66 innings for Milwaukee, but Bowman suggests Boyer stands "a good chance" at an Opening Day roster spot. If Boyer is indeed in the Braves' bullpen at the start of the season, he will likely pitch primarily in mop-up duty.
Cahill is coming off one of his best seasons, in which he posted a 2.74 ERA over 65.2 innings in relief for the Cubs. The right-hander, a former starter with Arizona back in 2014, could be a candidate to join the Padres' starting rotation, since multiple spots are seemingly up for grabs.
Watson, who will become a free agent following the 2017 season, was reportedly offered only a one-year deal. It's apparent that the southpaw's time in Pittsburgh is dwindling and it wouldn't be surprising to see the team's current closer traded. Teams such as the Mariners have inquired as to his availability. Felipe Rivero and Juan Nicasio would become candidates for saves in the event Watson is dealt.
Familia earned a raise of over $3 million by dominating out of the Mets' bullpen for a second consecutive season and posting a career-high 51 saves in 2016. Familia is in line to serve as the Mets' closer again this season, but he is still facing a potential suspension for a domestic violence incident during the offseason, so it remains to be seen if he will fill that role Opening Day.
The terms of the agreement were not announced. He figures to pitch in middle relief this season for the Giants and won't offer much fantasy value.
He is resting his ailing shoulder this winter, but is expected to be ready for spring training. Vizcaino is expected to enter the year as a setup man, and could be in the mix for saves if Jim Johnson falters in the ninth inning.
He pitched quite well out of the bullpen last year, posting a 3.18 ERA, 1.31 WHIP and 56:13 K:BB in 51 innings. However, he is not particularly close to competing for saves, and should see most of his opportunities in middle relief in 2017.
