ANALYSIS: I get why the Mariners are underdogs because they enter this series having lost seven of eight and are not hitting the ball. That said, those were all on the road. Seattle is 7-2 at home and batting .276 with an OPS of .829 at T-Mobile Park compared to .204 and .610 away. Reigning AL Cy Young winner Robbie Ray has a 3.00 ERA in two home starts with an opponents' batting average of .209 and he was very good vs. the Rays last year while with Toronto. Tampa Bay is just 3-13 in Seattle since 2016. The Rays' best reliever, Andrew Kittredge (1.46 ERA, 4 SV), surely won't be available after pitching each of the past three games. Seattle RL at -160.
