Boston Red Sox vs Seattle Mariners: Over 7.5 Total Runs (+100)
Odds correct at time of publishing
For this game, we need both teams to score enough runs to go over 7.5. The Boston Red Sox have been swinging their bats well, especially against left-handed pitchers, and they are playing at Fenway Park, where scoring runs is often easier. They have hit for a strong average against lefties this year, while the Seattle Mariners have really struggled against them.
The Mariners have trouble with left-handed starters, which could mean they won't score much tonight. Still, the game is rated close to a coin flip, so it could be a tight match. However, with both teams capable of putting runs on the board, I think we have a good shot at seeing more than 7.5 runs tonight.
Boston Red Sox vs Seattle Mariners: Boston Red Sox -1.5 Spread (+180)
Odds correct at time of publishing
The Boston Red Sox have been playing well lately, winning 6 of their last 10 games. They are strong against left-handed pitchers, hitting much better than most teams this year. With the Seattle Mariners struggling against lefties, this gives the Red Sox an advantage at Fenway Park.
Taking Boston to win by at least two runs seems like a good bet. While the odds are close, the Mariners have had a rough time on the road, winning only 27 games away from home. This matchup could be tight, but with Boston's good hitting form against lefties, they should be in a solid position to cover the spread.
That is the whole read on this one. Prices can move before you get on, so check the board at your bookmaker. Bet what you can afford to lose. If betting stops being fun, take a break.
