Oddsmakers keep giving the Mariners great runline prices (-130 here), and I'll just keep cashing on them -- Seattle is an MLB-best 14-4 on the runline this season. Seattle has one advantage here in that it was off Wednesday and thus will have a full bullpen, and that group has been fantastic this year, while the Red Sox lost Wednesday at home vs. Toronto. Boston hasn't seen Seattle starter Justin Dunn (1-0, 3.72) previously. Sox starter Nick Pivetta (2-0, 3.68) has walked 11 batters in his three starts and couldn't get out of the fourth inning last time out.
