Rangers at Mariners picks and predictions
Prediction
Mariners 3, Rangers 2
Moneyline
The MARINERS (-145) are 20-6 in their last 26 games at T-Mobile Park, while the Rangers are just 6-11 in their last 17 on the road. Texas may also be due for a letdown coming off its 1st series win at the Dodgers in over 20 years.
BET MARINERS (-145).
Run line/Against the spread
The Rangers +1.5 (-185) will likely hit, but it’s hard to beat MLB long term betting into 35-cent lines.
PASS. Bet the ML and/or total instead.
Over/Under
While Heaney has struggled overall this season, he has allowed a total of just 3 runs over his last 3 starts. Castillo has allowed 2 ER or fewer in 10 of his last 11 starts, and the Under has gone 6-0-1 in the last 7 meetings between these teams.
BET UNDER 7 (+100).
