The Seattle Mariners (63-54) and Kansas City Royals (38-81) open up a 4-game set at Kauffman Stadium Monday. First pitch is at 8:10 p.m. ET. Let’s analyze BetMGM Sportsbook’s lines around the Mariners vs. Royals odds and make our expert MLB picks and predictions for the best bets.
Season series: First meeting this season; Mariners won 4-2 last year
The Mariners come to town with cooled jets having lost 2 games in a row. Seattle had been on an 8-game win streak before that though, and is 14-6 over the last 20 games and sits 1 1/2 games out of the final AL Wild Card spot.
The Royals had a rare Sunday off and come into this one 2-6 over the last 8 games. They play a little better at home at 22-37 as opposed to 16-44 on the road. As expected, they struggle against AL West foes at 4-11.

Mariners at Royals picks and predictions
Prediction
Mariners 5, Royals 3
Moneyline
OF Julio Rodriguez has come alive since the All-Star break with a .274 average, 6 homers and 18 RBIs. The combination of him and Gilbert should be enough to secure this victory, and the Mariners aren’t priced out of range.
Take the MARINERS (-145).
Run line/Against the spread
The Mariners are 34-21 on the RL on the road, which is one of the better marks in baseball. During that 8-game winning streak, 6 of them were by multiple runs. Seattle is 7-3 over the last 10 against KC, and 4 of those were by more than a run.
LEAN MARINERS -1.5 (+115).

Over/Under
The Mariners are 3-6-1 O/U over the last 10, and KC is 6-4. The Over is 4-5-1 in the last 10 meetings between the teams. The Over is 3-2 in Gilbert’s last 5 starts and 4-1 in Singer’s last 5. So this one could go either way. I think I’m going to PASS on the total.
Head to the Win/Total section, and take the MARINERS AND OVER 5.5 (+105) for a better shot at a plus-money return.
