2025 World Series Odds: Alonso Guiding Mets to Glory

The New York Mets briefly stumbled, losing the top spot in the NL East to the Phillies by late May. Well, they've surged again as the Phils have waned and now look like one of baseball's top contenders.

So much can change in a few days. The New York Mets had loosened their grip on the NL East, allowing the Philadelphia Phillies to climb into first place.

Well, the Mets have won eight of 10 while the Phillies are 1-9 in the same interval, losing five straight through Sunday. The Mets' MLB odds have them at 10/1 — even with the Phillies despite this recent turn of events — while the Detroit Tigers have entered Top-3 consideration.

Here's a look at the latest 2025 World Series odds.

World Series odds analysis

The New York Mets exited their first real skid of the season by rattling off one of their best runs of success. The rotation still feels like a bit of a patchwork army, but it's remained effective despite feeling like it's been punching above its weight class.

And while Juan Soto hasn't put up otherworldly numbers worthy of the lofty contract he signed, he's still got a .384 OBP and has walked more often than he's struck out. Meanwhile, Francisco Lindor is in the NL MVP conversation as he has 14 home runs and 13 stolen bases while slashing .283/.354/.488.

But it's Pete Alonso's resurgence that has to be the linchpin for the team's offensive success. The Polar Bear leads the team with 17 home runs and 61 RBI while batting an absurd .301/.396/.594 with a 178 wRC+. That inflated average is buoyed a bit by an unsustainable .335 BABIP, but that doesn't negate the fact that he's walking more and striking out less while crushing the ball.

The Detroit Tigers own a seven-game lead in the AL Central and have seen their odds narrow to 8/1. Their +92 run differential trails only the New York Yankees (+95) in the AL. 

The Toronto Blue Jays are one of baseball's hottest teams (8-2 in their last 10) but haven't seen their odds shorten as much as their division rivals, the Tampa Bay Rays. They sport identical 35-30 records and trail the Yankees by just 4.5 games apiece, but the Rays are +5000 to win the Fall Classic while the Jays are +6600.

Sportsbooks likely take Tampa more seriously due to run differential, as the Rays have scored 48 more runs than they've allowed while Toronto has surrendered one more run than it's plated.
