From the weird start times to the idiosyncrasies of Fenway Park to the fact that the Mariners seem to always melt down spectacularly there, the annual trip to visit the Red Sox is one I personally dread. Thankfully, the Mariners have built up a decent clutch of wins over this long road trip, so even if they drop the series—or, gross, get swept—the worst they can do on this trip is 4-5, which feels acceptable for a long road trip covering two time zones, three cities, and two countries.
That 4-5 record looks pretty plausible, as FanGraphs doesn’t like the Mariners much in this series, giving them no higher than 46% odds to win any of these three games—and that puts a heavy burden on Bryce Miller, who has the best odds of the three back-end Mariners starters against the starters Boston is going to throw this series, in order to avoid the sweep.
