Mariners vs. Guardians Pick

Moneyline Pick for Mariners vs. Guardians

  • Mariners -145 (4 units)

Both teams have had their struggles of late with the Mariners dropping four of six while the Guardians have lost six of nine. Each is fortunate to be in watered down divisions so they still hold at least a share of their respective top spots despite sitting near the .500 mark on the year. Cecconi has pitched better of late but the fact remains that he is still struggling. Gilbert has gone 4-0 in his last five starts, allowing just six runs in 30.2 innings of work. Seattleโ€™s bats are still warming up but they get a well-pitched outing here and facing a flailing Guardiansโ€™ lineup, that delivers a win here.

Over/Under Pick for Mariners vs. Guardians

  • Under 8 (4 units)

Seattle has seen the under post a 41-38-3 mark in their opening 82 games. The Mariners are 25th in the majors with 4.04 runs per contest though that number climbs to 4.20 runs per game on the road. Seattle has an average total of 8.02 runs per contest and that number climbs to 8.52 runs per game away from T-Mobile Park. Cleveland entered Friday night having stayed under the total in 42 of their 81 games on the season. The Guardians are 29th in the majors with 3.95 runs per game, a number that falls to 3.92 runs per game at home. Cleveland has an average total of eight runs per game and that number drops to 7.81 runs per game at home this season. With Gilbert pitching well and neither lineup doing a ton of damage at the plate, take the under here.
