Mariners vs. Yankees: Under 8.5 total runs (-102)
The Mariners are starting Bryce Miller, who has a 3.08 ERA this season, while the Yankees are throwing Will Warren, who has been dominant in the majority of his recent starts. Outside of allowing six runs to the Phillies on July 26, Warren has a 2.11 ERA over his last three starts. The Mariners and Yankees are coming off a 4-1 New York win on Tuesday, going Under the total. The Yankees have gone Under this total in five of their last six games and the Mariners have gone Under it in four straight contests. The model projects another low-scoring affair, with the Under hitting in 58.7% of simulations. Bet the Under at DraftKings here and claim $150 in bonus bets after your first $5 wager as a new user:
Yankees (-124) to defeat Mariners
"At this point, we might as well keep fading the Mariners," SportsLine MLB expert Matt Snyder said. "They are now 23-35 on the road this season and are 5-14 since July 20. This team is broken. The Yankees have offensive issues, but still managed to grab four in an inning late against this sorry Mariners squad on Tuesday."

Blue Jays (+1.5) vs. Red Sox (-168)
Both teams are starting strong pitchers on Wednesday, with the Red Sox throwing Ranger Suarez (3.32 ERA) and the Blue Jays starting Jose Soriano (3.24 ERA). Soriano is making his second start for Toronto after being traded from the Angels, and he's allowed two runs or fewer in each of his last three starts. The Blue Jays have won each of the first two games of this series, as the Red Sox have lost four straight. The model projects the Blue Jays to at least keep this one close, backing Toronto to cover as 1.5-run underdogs on the run line in 66% of simulations.
