2023 MLB odds: Hot Seattle Mariners squad causes huge shift in World Series odds

On July 1, just a little less than a month ago, the Seattle Mariners were at +6000 to win the World Series, sitting at 39-42 and having lost five out of six games. They were in fourth place in the AL West, 10 games back of the division lead.

However, entering September, the Mariners are the talk of the sport, winning a MLB-best 37 out of 52 games since the first of July and now sitting in a tie for first place in the AL West.

Their World Series odds have moved to +1500, as Seattle has a pair of eight-game winning streaks this month and has won 12 of its last 14 games.

Could this be the year the Mariners end their World Series drought? Seattle is the lone MLB franchise to never play in the Fall Classic, and the Mariners are one of six active teams not to win a World Series.

Let’s take a look at Seattle’s betting odds in the midst of its hot streak, according to FanDuel Sportsbook.

Win AL West: +270 (bet $10 to win $26.50 total, third-best odds)
Win AL pennant: +600 (bet $10 to win $65 total, fifth-best odds)
Win World Series: +1500 (bet $10 to win $150 total, eighth-best odds)

Many thought the Mariners threw in the towel when they sent closer Paul Sewald to the Arizona Diamondbacks at the trade deadline. Seattle was 55-51 and still in fourth place in the division.

However, sparked by All-Star outfielder Julio Rodríguez‘s MLB-record four-game performance, the Mariners have surged up the standings and oddsboard.

Houston started the season as -200 favorites (bet $10 to win $15 total) to win the division, with the Mariners second at +300 and the Rangers tied for third with the Los Angeles Angels at +1000.

The Astros are the favorite to win the AL pennant at FanDuel (+270).

Count FOX Sports MLB Analyst Ben Verlander among the Mariners believers.

“The Mariners have certainty been the best story of the second half,” Verlander said on Monday. ” … On July 25, the Mariners were in fourth place in the AL West. And they were 8.5 games out of first place … and, overall in the American League, they were the fifth-worst team in the entire league. They were 10th out of 15 total teams. Now they have the third-best record in the American League. They’re rolling.

“You talk about peaking at the right time for certain teams. The Mariners were not even in the playoff conversation 30 games ago.”
