My 8* ROUND-TRIPPER is on the Seattle Mariners at 9:40 EST. The Mariners won 4-2 in the series opener and I believe they'll find a way to come out on top here on Friday as well. The A's produced just three hits and they struck out ten times yesterday. Jeffrey Springs was decent for the A's last year finishing 2-2 with a 3.27 ERA, but I still give the big nod to Luis Castillo, who was 11-12 with a 3.64 ERA and 175 K's. Look for the Mariners to build off a solid start and lay this price with confidence.
