Rumbelow was traded to the Mariners in exchange for minor-league pitchers JP Sears and Juan Then, Ryan Divish of The Seattle Times reports.

Rumbelow, who was recently added to the Yankees' 40-man roster to protect him from the Rule 5 draft, spent all of last season in the minors after missing almost all of 2016 due to Tommy John surgery. The 26-year-old split time between Double-A Trenton and Triple-A Scranton/Wilkes-Barre, posting a combined 1.12 ERA and 0.80 WHIP across 40.1 innings. He's looking to make it back to the majors for the first time since 2015 -- when he compiled a 4.02 ERA and 15 strikeouts in 15.2 innings with the Yankees -- and should have a clearer path in Seattle.

Pagan was traded to the Athletics along with Alexander Campos in exchange for Ryon Healy.

Pagan made his major-league debut in 2017, posting a respectable 3.22 ERA to go along with his 0.93 WHIP and 56:8 K:BB across 50.1 innings of work. The 26-year-old has shown the makings of a high-leverage reliever, as evidenced by his 2.45 ERA, 305 strikeouts and 51 saves across five minor-league seasons (257.1 innings). He'll factor into Oakland's bullpen next season, and there's a good chance he could see high-leverage opportunities for the A's.

General manager Brian Cashman said Green will enter spring training as a starting pitcher, Bryan Hoch of MLB.com reports.

Cashman noted that a return to the bullpen would be a fallback option for Green, who posted a remarkable 1.83 ERA, 0.74 WHIP and 103:17 K:BB across 69 innings while serving primarily as a reliever in 2017. The 26-year-old has flashed potential as a starter in the past, posting a 1.52 ERA, 0.94 WHIP and 100:21 K:BB in 16 starts (94.2 innings) with Triple-A Scranton/Wilkes-Barre in 2016, though he's yet to put it together in the majors (6.10 ERA and 1.51 WHIP in nine big-league starts). His role for 2018 will be determined in spring training.

May (elbow) threw 75 throws from 105 feet Monday, according to his personal Twitter account.

He was working on throwing from 60 feet back in August, so it sounds like he is continuing to progress in his recovery from Tommy John surgery, which he had in March. It is unclear when he will be ready for game action, but he could open the year on the DL.

Johnson will be tried out as a reliever in 2018, Pete Abraham of The Boston Globe reports.

Johnson split time between Triple-A Pawtucket and the Red Sox last season, compiling a 3.09 ERA in 17 starts for the PawSox and a 4.33 ERA in five starts for the big club. While he's worked solely as a starting pitcher through his first six seasons, the Red Sox -- who are in need of left-handed bullpen depth -- are set to try the 26-year-old southpaw out in a relief role. Johnson is expected to make the big club out of spring given he's out of options, so having him as a relief arm with the capability to spot start makes sense for a Red Sox team that is comfortable with their current starting rotation. At this point, it's unclear if the transition is a long-term move or simply for the 2018 season.

Martinez underwent surgery Monday to repair a sports hernia, Evan Grant of The Dallas Morning News reports.

At this point in time, it's expected that Martinez will be in full health once spring training arrives. During the 2017 season, Martinez posted an unimpressive 5.66 ERA and 1.37 WHIP over 23 games (111.1 innings). He's expected to be in the mix for one of the final spots in the Texas rotation to begin 2018.

Montgomery has agreed to a minor-league deal with the Tigers that includes an invitation to spring training, Anthony Fenech of the Detroit Free Press reports.

Montgomery spent all of 2017 with Triple-A Memphis, compiling a 2.43 ERA and 73:15 K:BB across 66.2 innings. Shoulder injuries halted his progress a few years ago, but the now-healthy 27-year-old is looking to prove he has what it takes to be a big-league reliever. He owns a career 2.35 ERA with 449 strikeouts across seven minor-league seasons (352.1 innings).

Kolarek agreed to a minor-league deal with Tampa Bay on Wednesday, Marc Topkin of the Tampa Bay Times reports.

Kolarek appeared in 12 big-league games for the Rays this past season, allowing six earned runs off nine hits and four walks while striking out four in 8.1 innings of relief work. The 28-year-old spent most of the season in Triple-A Durham, where he posted a 1.65 ERA and 46:16 K:BB in 41 games, and will likely begin the 2018 season back with the Bulls.

Santos was outrighted from the 40-man roster Monday, Mike Wilner of Sportsnet 590 The Fan reports.

For the first time in his career, the 26-year-old Santos threw in the majors during the 2017 season. He pitched 16.2 innings over 10 games and posted a 2.70 ERA to go with a 1.14 WHIP. However, it's entirely justified to wonder whether or not such a performance is sustainable for Santos. Between Double-A New Hampshire and Triple-A Buffalo in 2017, Santos appeared in 28 games (114.2 innings) and owned a collective ERA and WHIP of 4.16 and 1.26, respectively.

Rumbelow was added to the 40-man roster Monday, Brendan Kuty of NJ.com reports.

Rumbelow split the 2017 season between Double-A Trenton and Triple-A Scranton/Wilkes-Barre. He threw 29 innings across 17 games with Scranton/Wilkes-Barre. Over said games he posted a shining 0.62 ERA and 0.83 WHIP. After missing almost the entire 2016 campaign due to Tommy John surgery, Rumbelow will aim to build upon his recent performance during the upcoming season and reappear in the majors for the first time since 2015.
