Mariners #5: Jean Segura – 6.6 fWAR
Back in November of 2016, the Mariners shipped off Taijuan Walker and Ketel Marte for Mitch Haniger and Jean Segura. The trade looks even better now knowing that the Mariners have JP Crawford to man shortstop, who is under control for a few more years and is also five years younger than Segura.
Oddly enough, both players have amassed a 5.7 fWAR since being traded.
Segura’s best season with the Mariners was his second and final one in 2018. He looked to be back on track to being the player that had put up multiple 4.0+ fWAR seasons in his career. There was a bit of discontent and unknown with Segura after a closed-door fight supposedly sprawled through the doors and into the eyes of the media.
He would turn in a slash line of .304/.341/.415, making it three straight years with a batting average of .300 or higher for Segura. He still had a bit of speed as he swiped 20 bases, and just barely turned in the third-best offensive season of his career. It was a bit better on defense, trailing only his rookie year. At 3.7 fWAR, it was actually the highest fWAR by a non Alex Rodriguez shortstop in Mariners history.
It seemed like the Mariners traded him at the perfect time, acquiring someone who had the potential to become a long-term Franchise Shortstop. Segura was a Mariner for only two seasons but did quite well in his time here.
