Analys

Washington has the best offense in the league right now. They are putting up 5.4 runs per game, which is a massive number for a full season average. Today they face Griffin Jax, who has been solid with a 3.00 ERA recently, but the model still sees plenty of runs on the horizon. The total is set at 7.5, but our projection is sitting at 8.6. That gives us a huge 14.1 percent edge on the over. Cade Cavalli is starting for the Nationals and he carries a 3.98 ERA into this matchup. Tampa Bay is a middle of the pack offense, ranking 16th in the majors, but they still manage 4.4 runs per game. When you look at the defensive rankings, Washington is near the bottom at 28th. This is a recipe for a high scoring affair. Even if Jax pitches well, the Washington bullpen and the Tampa offense should do enough to push this over a relatively low total. The Nationals have been playing well lately, going 6 and 4 in their last 10 games. They are also excellent against the spread on the road, covering in 76 percent of their away games. Tampa Bay covers 70 percent at home, so something has to give. The model leans toward Washington covering the minus 1.5 spread, but the strongest play is definitely the total. Expect the Nationals to keep swinging hot bats in this one.

The public usually sees Tampa Bay as a pitching powerhouse and hammers the under. They are ignoring that Washington currently has the most productive lineup in baseball and a defense that gives up plenty of runs.

We are looking at a 14.1 percent edge on the over in the Washington game, and while this Seattle game has a smaller edge at 8.1 percent, it is still a strong play. The line is set at a very low 7 runs. Emerson Hancock and Connelly Early are the projected starters, and while both teams have decent pitching stats, the model thinks 7 is just too low. Seattle scores 4.2 runs per game and Boston scores 3.9. If both teams just hit their averages, we are already at 8.1 runs. Seattle is also a lean at plus 1.5 on the spread. They are 38 and 37 on the year and their defense is ranked 6th in the league. Boston is struggling badly, sitting 13 games under .500 and ranking 29th in offense. It is hard to trust the Red Sox to cover a spread on the road when they only cover 46 percent of the time in that spot. The Mariners have not been great at home for bettors, covering only 35 percent of the time, but getting 1.5 runs in what should be a low scoring, tight game is valuable. But Boston has lost 7 of their last 10 games and they look like a team that is ready for the break. Seattle has a much better defensive foundation to lean on here. Take the Mariners to keep it close and bet on these teams to combine for at least 8 runs.

Casual bettors see two struggling offenses and immediately look at the under. They are missing the fact that these specific starters are prone to giving up just enough to clear a tiny line like 7.

Miami is in a great spot tonight against a San Francisco team that is likely exhausted. The Giants are playing on the second night of a back to back and they had to travel to Miami. The Marlins have been resting for two days. In the heat of June, that rest advantage is huge. The model sees Miami as a slight favorite to win, giving them a 52.7 percent win probability, yet we can get them at plus 1.5 on the spread. Landen Roupp takes the mound for the Giants, a team that ranks 22nd in defense. Miami is not an offensive powerhouse, but they are efficient enough at home, where they cover the spread 51 percent of the time. The Giants only cover 46 percent on the road. San Francisco allows 4.4 runs per game, which is more than they score. Miami is the opposite, scoring 4.3 and allowing only 4.0. The head to head history this year shows these teams play each other very close. The average margin of victory in their three meetings is less than a run. With the travel fatigue and the rest discrepancy, Miami should be able to at least keep this within one run. But the real value is on the home dog. Trust the fresh legs of the Marlins to give the Giants a hard time tonight. They might not win the game outright, but they should keep it competitive until the final out.

The public often bets on the bigger name brand like the Giants, especially when the Marlins have a losing record. They are completely ignoring the travel schedule and the two days of rest Miami just enjoyed.
