Astros vs. Mariners Best Prop Bet

Luis F. Castillo OVER 3.5 Strikeouts (-135) via BetMGM

The Astros have had bad plate discipline this season. Entering today's games, Houston sports the second highest strikeout percentage in the Majors, striking out on 26.8% of their plate appearances. To take advantage of that, I'm going to take Luis F. Castillo to record at least four strikeouts. He recorded two in just 3.0 innings in his opening start so if he can stretch out his start to a few more innings, he has a great chance of hitting this number.

Astros vs. Mariners Prediction and Pick

In today's edition of "Walk-Off Wagers," I broke down why I love the UNDER in this AL West showdown:

The Astros and Mariners have been two of the worst offenses in the Majors this season. The Astros rank 26th in batting average at .202 and the Mariners are 28th at .199. The Astros also rank dead last in OPS at .573.

On top of that, the Hunter Brown gets the start for the Astros. He dominated the Mariners last season, sporting a 1.61 ERA through four starts against them.

The smart move is to bet the UNDER in this AL West showdown.

Pick: Astros/Mariners UNDER 7.5 (-118)
