The Seattle Mariners look to even their series against the Cleveland Guardians after suffering a walk-off loss Friday night that saw the home team rally from an early 4-0 deficit to win 5-4. The Mariners enter Saturday with the third American League Wild Card spot with a three-game lead over the Kansas City Royals, while the Guardians are four back of Seattle for that final playoff spot. Cleveland can make up even more ground this weekend, starting with Saturday's game, which begins at 7:15 p.m. ET on FOX.

The Mariners turn to Logan Gilbert (4-5, 3.69 ERA) on Saturday while Cleveland will start Gavin Williams. Gilbert is coming off six innings of one-run ball in his last start with 13 strikeouts against the Athletics, but he has a road ERA of 6.00 on the year. Williams has been great in August with a 2.73 ERA in five starts, but he allowed three runs in just 3.1 innings in his last outing against the Rangers.
Gilbert's strikeout prop is at 6.5 (Over -144, Under +106) at FanDuel Sportsbook. Williams' is at 5.5 (Over -110, Under -118). The SportsLine Projection Model is suggesting to take Under for Williams with a projection of 5.2 strikeouts (3.5 stars out of 5) and the Over for Gilbert with a projection of 6.8 punchouts (3 stars out of 5).
Mariners catcher Cal Raleigh leads all of MLB in home runs with 50, but Phillies slugger Kyle Schwarber is right behind at 49 after a recent four-homer outburst. Raleigh has the shortest odds to go yard in this contest at +290, with teammate Eugenio Suarez next at +400. Guardians star Jose Ramirez has the third-lowest odds for this market at +460.
