Mariners vs Royals Prediction

The current betting odds have the Royals listed as a slight favorite in this game according to Draftkings Sportsbook. The Royals have looked good in their games this season with their 38-26 record overall which has them in 2nd place of the AL Central, right behind the Guardians in 1st place. They have been a completely different team at home this year with their 23-10 home record, playing a lot better in those games. Meanwhile, the Mariners have been really similar with their 36-29 record overall which leads the AL West right now, but they haven't looked nearly as good in their road games with their 15-18 road record. They lost the series opener to the Royals and that was a terrible game to lose since the Mariners had an 8-0 lead in the game. The Mariners will have Kirby starting in this game, but he is 5-5 with a 4.05 ERA this year. He only gave up 2 earned runs in his last start, but he has been giving up more runs in his starts all season and that will be trouble since the Mariners bullpen showed they can't even hold onto an 8 run lead. The Royals have Ragans starting in this game and he has been one of their best starters this season, going 4-4 with a 3.21 ERA. His team has won 3 of the last 4 games he started in and he only gave up 1 earned run in his last start. The Mariners have struggled on the road all season while the Royals have looked a lot better in their home games, and the Royals also have the better offense too. The best way to place a bet here is on the Royals to win this game. 

Mariners Royals Prediction:  Our MLB Pick for Sunday, June 9, 2024 (2:10 pm ET start time) is Royals 6 Mariners 4.
