MLB Favorites and Underdogs on Thursday
With our $50 in Bonus Picks ready to roll, we have a wealth of options on the board. Let’s look at the full-game moneylines for today’s MLB matchups. I always start by scanning the board to see where the real value lies between the heavy chalk favorites and the live underdogs.
| Matchup | Favorite (ML) | Underdog (ML) |
|---|---|---|
| New York Yankees @ Baltimore Orioles | Yankees (-123) | Orioles (+110) |
| Washington Nationals @ Texas Rangers | Rangers (-163) | Nationals (+146) |
| Los Angeles Angels @ Houston Astros | Astros (-181) | Angels (+162) |
If you’re deploying that initial $10 entry, the matchup between the Los Angeles Angels and the Houston Astros is a textbook spot to decide your strategy. If we lay the juice and back the heavily favored Astros (-181), a $10 spend yields a modest profit of $5.52. But if you’re like me and love chasing a nice payday, taking a shot on the underdog Angels (+162) turns that same $10 into $16.20 in pure profit if they manage to pull off the upset.
Another board catching my eye features the Washington Nationals visiting the Texas Rangers. A $10 entry on the favored Rangers (-163) nets us a $6.13 profit. However, if you think the Nationals have a real chance as +146 underdogs, that $10 spend would profit you an exciting $14.60.
Matchup Trends and Breakdown
When handicapping these lines, we need to look past the morning line and dig into actual team performance. The Astros are sitting with a winning 64-63 record, comfortably making them the clear favorites against a struggling Angels squad sitting at 50-77. Sometimes, taking the reliable favorite is the smartest way to build your confidence and your balance.
However, let’s look at that Rangers (62-65) vs. Nationals (61-67) matchup. Texas is favored at home, but my breakdown shows Washington might hold some serious hidden value. Even as underdogs, the Nationals are swinging the bats slightly better, boasting a .251 overall team batting average compared to the Rangers’ .242. That statistical edge at the plate is exactly the kind of angle I look for when I want to back a live dog to disrupt the home team’s momentum.
