KC @ DETKC 34.1% / DET 65.9%

When I'm handicapping a slate, I always look at the extremes to see where our bankroll is best spent. If we put a $20 trade on today's heaviest favorite—the Detroit Tigers—we're looking at a steady $9.09 profit for a total payout of $29.09. On the flip side, if we want to chase a bigger payout, dropping that same $20 on the heaviest underdog—the Kansas City Royals—would bring back a sweet $36.20 profit if they can pull off the upset.

Let's dig into the stats to see why the morning line looks the way it does. In that KC @ DET matchup, the Royals actually boast a better team batting average (.248 vs. .235). However, Detroit is heavily favored because they hold a massive edge on the mound, carrying a 3.64 team ERA against Kansas City's shaky 4.93 ERA.

Meanwhile, the odds for TB @ TOR are nearly a pick 'em, but I'm looking closely at Tampa Bay here. The Rays entered the second half of the season with the American League's best record, operating as potential aggressive buyers with a stacked farm system.

The Blue Jays, on the other hand, are suffering through a disastrous season and are far from playoff contention. The stats back this up: Tampa Bay holds the edge in team ERA (3.84 vs. 4.18) and batting average (.261 vs. .241). It's advantageous matchups like this where our bonus funds can really go to work.
