With the M's moving from a best-of-three series into a best-of-five series, they have decided to keep the same squad and not add another starting pitcher. Jon Morosi of MLB Network relays that lefty Marco Gonzales and righty Chris Flexen are with the team but not on the roster.

Gilbert was slated to start the third game of the wild-card round but will now be able to start this series due to the Mariners sweeping the Blue Jays. The club hasn’t announced its plans going forward, but it would seem like Luis Castillo and Robbie Ray should follow in the next two contests. This year’s ALDS features an unusual schedule, with off-days after Game 1 and Game 2, followed by three consecutive games after that, if necessary. That means that Gilbert could potentially start Game 4 on regular rest, and Castillo could start Game 5 on short rest. Alternatively, the Mariners could turn to Kirby for a start or some bulk innings at some point. Regardless of how it plays out, the club evidently feels good enough about its options to proceed without Gonzales or Flexen.
