Mariners vs Giants Prediction

I just don’t believe in the Giants stringing wins together, so excuse me for fading them despite putting together a decent stretch. Webb has also been a mess in his last 10 innings, allowing 16 hits and 12 runs. The Mariners are a talented team that’s due for a feel-good victory, and Woo has been money at home through 51.1 frames with a 2.10 ERA and a .156 allowed batting average. I’ll lay the cheap price with the Mariners at home.
