They've already taken one step toward that goal by trading for James Paxton from the Seattle Mariners.
Corbin, a two-time All-Star left-hander in Arizona, agreed to a six-year, $140 million contract, according to the Washington Post.
So, where will general manager Brian Cashman turn next?
Other lefties that intrigue the Phils include Yusei Kikuchi, who is about to come over from Japan.
Nathan Eovaldi delivers a pitch for the Red Sox during the seventh inning of Game 1 of the World Series against the Los Angeles Dodgers at Fenway Park on October 23, 2018 in Boston. Clay Buchholz is a free agent while Taijuan Walker is recovering from Tommy John Surgery. He went 3-4 in 10 starts before being dealt to the Boston Red Sox prior to the trade deadline. He went 2-1 with two holds and a 1.61 ERA over 22.1 innings in the playoffs. He had a 3.81 ERA in 111 innings and impressed during Boston's postseason run.
While the news was good for the Red Sox in that Corbin didn't sign with their rival New York Yankees, the pitcher's decision still could cost Boston when the dust settles this offseason. Of the bunch, Keuchel is subject to draft-pick compensation for a new team after rejecting a one-year, $17.9MM qualifying offer from the Astros.
Comparatively, National League Cy Young award victor Jacob deGrom and Trevor Bauer were the only two players to rank above Corbin in the FIP category. deGrom had a phenomenal 1.99 FIP and Bauer had a solid 2.44 FIP. Although these numbers far exceed his career 3.91 ERA, his career 3.65 FIP, and his career 1.285 WHIP, he may have very well finally put everything together during his age-28 season. ESPN's Buster Olney reports that the southpaw is likely to receive the biggest pitching contract of the offseason. Eovaldi went 14-3 with NY in 2015 before undergoing Tommy John a year later and missing the entire 2017 season. Whether or not it will occur before next week's MLB Winter Meetings remains to be seen.
