Mariners vs Cubs Prediction 
Seattle was able to score nine runs in their win on Friday to start this series, but they have struggled to string wins together, as they have alternated wins and losses in their last five games. The Mariners are 18-17 on the road this year, while the Cubs are 24-14 at home. Chicago has allowed 17 runs in their last two games and they are starting Horton, who has allowed two earned runs or fewer in four of his last five starts. Seattle is going with Hancock, who has allowed two earned runs or fewer in four straight outings. I have been backing Hancock in recent starts, but I don’t love his matchup here on the road. Take the Cubs -1.5 in this game.
