Seattle Mariners DFS Spin
Mariners third baseman Eugenio Suarez had a monster day at the plate in his team’s 6-2 win over the Blue Jays on Friday night in Game 6 of the ALCS. In that game, the 2-time All-Star went 2 for 3 with 2 homers, 5 RBIs, a walk, and 2 runs scored. During the regular season, Suarez hit .228 with 49 homers, 118 RBIs, 4 steals, and an OPS of .824 across 588 at-bats. Eugenio Suarez is batting .267 with an OPS of .886 in 4 road games during these playoffs, making him an appealing DFS option on Sunday.
Toronto Blue Jays DFS Spin
Blue Jays third baseman Ernie Clement drove in half of his club’s runs in their 6-2 loss to the Mariners on Friday. Hitting out of the #6 spot in the lineup, the Rochester, NY, native went 1 for 4 with a single and an RBI. Across 545 regular-season at-bats, Clement hit .277 with 9 homers, 50 RBIs, 6 steals, and an OPS of .711. The 29-year-old right-handed hitter is batting .429 with an OPS of 1.003 in 9 playoff games this year. That fact makes Ernie Clement worth a look in most DFS formats on Sunday.

What’s more, Toronto is 69-54 straight up in American League games and 67-48 straight up in non-division games in 2025. And finally, the Blue Jays are 56-29 straight up as the home team and 55-39 straight up as a favorite this season. The pick is Toronto -125 on the money line over Seattle at Bovada.lv.
