Seattle Mariners and Oakland Athletics will play a do-or-die set on Monday. Chris Flexen will start for the Mariners. Cole Irvin will be starting for Oakland. The Athletics are struggling with their bullpen ERA. Seattle has won six of Flexens' last eight starts and the last 8 in the season series against Oakland, which is a playoff contender.
