Mariners vs Astros Prediction
The Mariners won six of the previous ten H2H encounters, including four of the last five. Each of the past five H2H duels produced 7+ runs, and I am going to lower this total a bit and back Over 6.5. Framber Valdez posted a 5.16 ERA in four starts against Seattle last year, while Luis Castillo had a 3.46 ERA in two starts against Houston. I think both will allow multiple runs in the first five innings. Go with Over.
