In this Rangers vs Mariners Prediction, the Mariners are coming as -160 home favorites. I don’t like the pitching in this matchup, as both starters have a combined 9.85 ERA and are both coming off their worst starts of the season. Both offenses have been red-hot, scoring 11 runs combined in their last 10 games and both bullpens have been in terrible shape in the same span, with a combined 11.59 ERA. The opening game of the series had 15 total runs, so take the over 7.5 in this one.
