Phillies Mariners Free Pick: Phillies ML -118
Here is my Phillies Mariners free pick: Philadelphia is riding a nine-game winning streak, and I’m not looking for reasons to jump off now.
The Phillies are simply playing better baseball.
Philadelphia has also been dependable away from home with a 35-28 road record, taking away one of the usual concerns when backing a visitor. Seattle is 3-2 over its last 5, but that doesn’t compare with what the Phillies are doing.
The betting results strengthen the case, with Philadelphia covering the run line in 4 of its last 5 games. Additionally, the offense continues producing enough runs to give this team multiple ways to win. Hot is hot.
Nine straight victories tell me Philadelphia deserves to be trusted until somebody proves capable of cooling this team down.
Seattle has a respectable home record and enough offense to make this competitive. However, recent head-to-head history has also favored Philadelphia, adding another piece to an already strong handicap.
Why fight this streak for a modest favorite price?
I’m not doing it. The Phillies are winning everywhere, traveling well, and consistently rewarding bettors during this run.
My MLB betting system points to the Phillies -118, and I’m riding Philadelphia’s momentum for another game.
