Mariners vs. Athletics Best MLB Prop Bet
- Cole Young UNDER 0.5 Hits (+134) via DraftKings
Cole Young has struggled against left-handed pitchers this season. His batting average drops from .256 against eighties to .200 against lefties. He'll face a lefty in Jeffrey Springs of the Athletics tonight. Young is 0-of-2 against Springs in his career, and he was held without a hit against the A's last night.
Mariners vs. Athletics Prediction and Pick
In today's edition of Walk-Off Wagers, I broke down why I'm betting the Athletics as home underdogs:
The Mariners' offense has been terrible against left-handed pitchers this season. Their OPS drops from .734 against right-handed pitchers to .607 against left-handed pitchers, which is the third-lowest OPS in all of baseball against lefties.
Tonight, they'll take on a lefty in Jeffrey Springs of the Athletics. He has kept this Mariners lineup to a batting average of .197 throughout his career.
That alone is enough for me to back the Athletics as home underdogs.
