Betting on the All-Star game seems like the kind of thing that might finally convince someone they have a serious gambling problem, so I’ll pass this along purely from a “this is sort of interesting” standpoint: Tonight the American League are -140 favorites over the National League.
For the non-degenerates in the crowd, that means to win $100 betting on the American League to win you’d have to risk $140. For that to be profitable the AL would have win about 60 percent of the time (they’re the “home” team and home teams during the regular season have won 52 percent of the time).
On one hand the National League has actually won back-to-back All-Star games. On the other hand the American League has won interleague play every season since 2004. And on a third hand … don’t bet on the All-Star game.
