The Seattle Mariners (56-62, 33-28 Home) will host the Tampa Bay Rays (70-46, 29-28 Away) in the finale of their weekend series at T-Mobile Park. First Pitch for this exciting matchup is scheduled for 4:10 p.m. EST on MLB.TV.

It has been a low-scoring but competitive series. Tampa Bay took Friday’s game, 2-1. Seattle got on the board first yesterday with a run in the second, only to lose 3-2 in the end.

Emerson Hancock is scheduled to start for the Mariners. Hancock is 6-6 on the season in 21 starts with a 3.33 ERA and a 1.07 WHIP. Teams have been hitting just .223 against him. He has pitched well at home, where he is 3-3 in 11 starts with a 3.08 ERA and a .208 OBA. In his previous start vs. the Rays, he was pulled after 1 2/3 innings due to an injury, but gave up no hits or runs, walked one, and struck out two.

Ian Seymour is scheduled to get the start for Tampa Bay. Seymour is 8-3 in 37 appearances (eight starts) with a 4.27 ERA and a 1.13 WHIP. Teams have hit .216 against him. However, he has not always had his best stuff on the road, where he has a 5.21 ERA and teams have hit .252 against him (but he is 4-1in 17 appearances with three starts).

Our Seattle Mariners vs Tampa Bay Rays Prediction

I get it; home teams are often considered the betting favorite because everyone plays better at home. But that hasn’t been the case in this series and in recent games. Seattle has hit .231 over the last week and recorded just 13 runs in six games. Tampa Bay has hit .261 with 29 runs in six games. Both starters have been good, but not great, and Seattle has a slight edge in the bullpen (3.77 ERA to 3.99). The data screams for another low-scoring game, but the total is really low (7.5). Tampa Bay is in a great position to complete the series sweep today.
