This fan of the Seattle Mariners and James Paxton wishes the lefthander well in New York.
However, I found this comp interesting (if not particularly meaningful):
James Paxton and Erik Bedard are Canadian lefthanders who were involved in major Seattle Mariner trades, each with two years of team control remaining.
The Baltimore Orioles traded a 29-year-old Bedard to the Mariners when the southpaw was coming off a 2007 season with this line:
182 IP, 28 GS, 13-5 W/L, 3.16 ERA, 1.09 WHIP, 3.88 K/BB, 146 ERA+, 5.7 bWAR, 5.0 fWAR
The Mariners traded a 30-year-old Paxton to the New York Yankees when the lefty was coming off a 2018 season with this line:
160.1 IP, 28 GS, 11-6 W/L, 3.76 ERA, 1.10 WHIP, 4.95 K/BB, 108 ERA+, 2.9 bWAR, 3.8 fWAR
Compare their career lines at the time of each trade:
EB 658 IP, 114 G, 111 GS, 3.83 ERA, 1.34 WHIP, 2.52 K/BB, 118 ERA+, 12.8 bWAR, 15.5 fWAR
JP 582.1 IP, 102 G, 102 GS, 3.42 ERA, 1.19 WHIP, 3.67 K/BB, 117 ERA+, 10.9 bWAR, 14.1 fWAR
The Orioles traded Bedard for outfielder Adam Jones (who had lost his prospect status with a lackluster MLB debut after being Baseball America's 28th-ranked prospect the previous spring), righthander Chris Tillman (BA's 67th-ranked prospect after the trade and 22nd-ranked prospect the following year), three years of lefty reliever George Sherrill (who made the All Star team in 2008 before fading), righthanded reliever Kam Mickolio (whose MLB career was limited to 29 games) and lefthander Tony Butler (who never pitched above Double A).
The Mariners traded Paxton for lefthander Justus Sheffield (BA's 41st-ranked prospect a year ago and MLB Prospect Watch's 31st-ranked prospect this year), as well as two unranked prospects: righthander Erik Swanson and outfielder Dom Thompson-Williams.
Again, interesting but not necessarily meaningful.
