MLB betting: Dodgers bettor got an 8th inning homer from Zach McKinstry to win a $127,500 bet

There are two popular ways to bet on a baseball team: The moneyline and the run line.

The run line is MLB's version of the point spread. It's always 1.5 and using it for a big favorite, like the Los Angeles Dodgers, takes their odds way down. On Wednesday night against the Colorado Rockies, the Dodgers were -260 odds on the moneyline (bet $260 to win $100), but if you took the Dodgers at -1.5 they were just -125.

The problem, of course, is that a one-run Dodgers win is a loser for run-line bettors. And one bettor who had a massive bet on the Dodgers run line Wednesday night was looking at that exact problem, before he caught a huge break in Los Angeles' final at-bat.

Big Dodgers bet comes in Wednesday

On Wednesday, BetMGM took in a rare six-figure bet on a regular-season baseball game.

You don't see bets that large on MLB too often, but the Dodgers are a machine and the Rockies are one of the worst franchises in baseball.

But this is still professional baseball, and the Rockies aren't entirely incapable. Into the bottom of the eighth, Colorado trailed just 3-2. The big bettor's options were running out. Even if the Rockies somehow tied it in the top of the ninth, a two-run win in the bottom of the ninth or extra innings requires a walk-off homer with men on base. The Dodgers needed to score an insurance run in the bottom of the eighth for the bettor to cash a six-figure ticket.

Big homer wins the bet

Zach McKinstry has been a surprise story so far this season. In a lineup jam packed with stars, with good players on the bench, McKinstry has gotten a chance to play and is doing the most with it. Before Wednesday's game he had a couple homers. Before this season he had seven career MLB at-bats with a single and a double to his name. He's a 33rd-round pick who had 11 homers his first three minor-league seasons before breaking out with 19 home runs at Triple-A in 2019.

And, on Wednesday night, his third career MLB homer won someone about $100,000.

In the top of the ninth, Kenley Jansen struck out the side after a leadoff walk. The Dodgers won 4-2, winning on the run line.

McKinstry, whose salary this season is $573,000, helped a bettor win six figures on one swing of the bat.
