STORYLINES TO WATCH
- The Mariners searched high and for arms when injuries struck the rotation in 2017. Only three of their pitchers logged more than 20 starts. Three others – including RHP Felix Hernandez (0.8 WAR) – made 10 or more starts and 17 in total started games for the Mariners. Seattle will hope for better luck in 2018, especially from LHP James Paxton, who enjoyed a career year despite injuries limiting him to 136 innings.
- Dee Gordon is among the fastest runners in baseball and the Mariners believe that will translate to a successful conversion to center field. Seattle acquired him and international bonus money from Miami for three minor leaguers and immediately planned to use his athleticism in what the Mariners’ hope is one of baseball’s best defensive outfields.
- 2B Robinson Cano is 35 years old and declined from 7.3 WAR in 2016 to 3.4 last year. DH Nelson Cruz drove in a career-high 119 runs in 2017 but will turn 38 in July. Both veterans remain plenty productive, but their window to return the Mariners to the postseason could close quickly.
- 82 wins
