New York Yankees vs Seattle Mariners Prediction

The Yankees looked flawless against the Giants and have rest heading into this series, but I’m not excited about Weathers, who is pitching in his sixth season and has yet to top 100 innings in a year. The Mariners were a sexy pick to win the World Series this season and while we’re a long way away from that, this feels like an early measuring stick game where players and the crowd will be up for it. Castillo is a vet who got back his all star caliber ways last season and had a 2.60 ERA and .192 allowed batting average in 100.1 home innings. I’ll roll with the Mariners in this intriguing series opener.
