Mariners vs. Red Sox Key Players to Watch

Seattle Mariners

Randy Arozarena: Arozarena has hit the ground running with the Mariners, batting .375 with a home run and two runs batted in in four games with his new club after being traded from the Tampa Bay Rays. Can he keep it rolling against the Red Sox?

Boston Red Sox

Rafael Devers: Among the best hitters in baseball, hitting .301 with 24 home runs, Devers is off an awesome outing against the Mariners, going three-for-five with a home run and four runs batted in. Can he get Boston back in the win column? 

Mariners vs. Red Sox Prediction and Pick

George Kirby has been on a tear of late, posting a 1.88 ERA in his last 10 starts while punching out more than six batters per start. However, he’ll face a stiff test with the Red Sox operating at a high level at the plate. 

With the Mariners suspect offense on the other side, 20th in OPS since the All-Star break, I’m going to side with the home underdog Red Sox, who are second in OPS in that same timeframe. 

PICK: Red Sox (-105)
