Let’s talk numbers. If you take a standard $20 trade and back the day's heaviest moneyline favorite, the Houston Astros (-181), a winning ticket returns a steady profit of $11.05. On the flip side, if we are feeling bold and throw that same $20 on the biggest underdog on the board, the Los Angeles Angels (+162), a massive upset would yield a handsome $32.40 payout.

When I am handicapping the LAA @ HOU matchup, the Astros easily justify their heavy favorite status. Houston boasts a solid .242 team batting average and has crossed the plate 580 times this season, comfortably outpacing the Angels (.235 average, 512 runs). While Los Angeles holds a marginal edge on the mound (a 4.362 team ERA versus Houston's 4.551), they are currently navigating chaos behind the scenes.

The Angels recently fired pitching coach Mike Maddux, with interim GM John Mozeliak citing a necessary pivot toward analytics. Throwing interim pitching coach Tim Leveque into the fire against a potent Houston lineup makes backing the Astros at home a very compelling bet.

There is plenty of value elsewhere, too. In Arlington, keep an eye on Jacob deGrom taking the mound for the Rangers against the Nationals; he's approaching a notable career strikeout milestone and should be dealing. Meanwhile, if you're looking at NYY @ BAL, keep in mind the Orioles are coming off a highly emotional, controversial loss after a disputed foul ball call involving Pete Alonso. Expect manager Craig Albernaz and the O's to come out swinging at Camden Yards.
