The MLB Double System Dominator is on Seattle at 7:10 eastern. The Mariners fit an undefeated game 6 specific system where road teams are perfect if they have 2 or more wins and are taking on a team that scored 4 or less runs. Conversely game 5 home teams like Chicago that have 3 or more wins on the year are 1-3 vs a team that scored less than 3 runs. We went with the Chisox and cashed on Tuesday. However the Mariners have solid advantages here. Dating to last season the Mariners have won 8 of 9 vs a lefty, 14 of 17 vs a team that allowed 2 or less, 7 of 8 vs a winning team and 8 of 10 after scoring 2 or less runs. R.Ray was solid in his last start vs Chicago. Keuchel has struggled vs Seattle with his teams losing 5 of 6. Look for Seattle to get the win.
