HOU +105

Join Discord for earlier access: https://discord.gg/HjKxYKdSUy This is a Castillo fade more than a Houston form bet. Castillo is 0-4 with a 6.57 ERA and 1.617 WHIP through 8 starts. Houston only needs Burrows to be the less messy starter at home, and +105 prices in the ugly record.

Over 9-105

L.Castillo o5.5 Ks+123

1.23u

There is a value opportunity on Luis Castillo's strikeouts prop. THE BAT X is projecting 6.03 strikeouts for him with a 56% chance that he records at least 6 strikeouts. If you can get the over at +123 or better, there is great value here. This play is good down to at least -105. Love THE BAT X?
