In a season that's been dominated by two incredible teams — the Tampa Bay Rays and Atlanta Braves — it's the teams not making noise that have everyone talking.

The New York Mets, St. Louis Cardinals, and San Diego Padres, all with lofty World Series expectations heading into the year, now face a very real possibility of missing the postseason entirely.

As we approach the All-Star break and general managers begin looking ahead to their plans for the MLB trade deadline, a handful of managers are starting to feel the heat.

MLB odds now allow us to wager on the first manager to be fired, and there are some notable names on the list, although no clear favorite has emerged yet.

Let's take a closer look at which managers could be given their walking papers sooner than expected.

First MLB manager fired

Buck Showalter (+300)

If you look up “disappointment” in the dictionary, you would see a picture of the 2023 New York Mets. This is a team that was a preseason favorite to win the World Series but instead find themselves seven games below .500, 18 games back of the first-place Atlanta Braves, and 6.5 games out of the final Wild Card spot.

Everything that has could go wrong for the Mets has and the scapegoat for this mess may be Buck Showalter. He’s shown countless times this season that he just cannot manage a dugout or a bullpen.
