Before making any Mariners vs. Nationals picks, you NEED to check out the MLB predictions from the SportsLine Projection Model.
The SportsLine Projection Model simulates every MLB game 10,000 times , and it is 275-236 on top-rated MLB money-line picks since the start of the 2021 season, returning over $400 for $100 players. This is the same model that pegged the 2021 Atlanta Braves at 10-1 as one of three best bets to win it all last season. Anybody who has followed it has seen profitable returns.
The model knows the Mariners are red-hot right now. Seattle is 16-3 in the last 19 games, playing at a sky-high level. The Mariners are in the top three of the American League in walks, with above-average marks in triples, on-base percentage, and OPS. Seattle rookie phenom Julio Rodriguez leads the AL in stolen bases, and he is playing at a star level at the age of 21.
The model also knows the Nationals have clear offensive strengths. Washington leads the National League with only 634 strikeouts this season. The Nationals are also in the top five of the league in both hits and doubles, with above-average marks in batting average and on-base percentage among NL teams. Two- time All-Star Juan Soto leads the way with an NL-leading 73 walks and plenty of power.
