Pick 3: Gerrit Cole under 8.5 strikeouts (-126) FanDuel.

Cole is 9-4 on the year with a WHIP of 1.04 and ERA of 3.56. Cole also has 170 Ks in 131.1 innings pitched good for 1.29 Ks per inning. In this scenario we would need the Mariners bats to force Cole off the mound before the 7th inning or for Cole to have a very long first or second inning.
The last time he faced the Mariners he finished on the hook with 8 leaving his 1-0 to the under against the mariners.
