MLB Totals for Sunday
Once we have those bonus entries secured, the July 19 slate is serving up some incredibly intriguing over/under lines. If you are looking to swing for the fences, several batters are staring down elevated 1.5 hit totals today, while some top-tier arms feature tightly contested strikeout props.
Here are the eight players with the highest hit over/unders on the board, alongside two starting pitchers I’ve got my eye on:
- Riley Greene (Detroit Tigers) vs. LAA – 1.5 Hits (Over +199 / Under -277)
- Kevin McGonigle (Detroit Tigers) vs. LAA – 1.5 Hits (Over +186 / Under -258)
- Ivan Herrera (St. Louis Cardinals) vs. AZ – 1.5 Hits (Over +190 / Under -278)
- Gabriel Moreno (Arizona Diamondbacks) vs. STL – 1.5 Hits (Over +187 / Under -254)
- Ketel Marte (Arizona Diamondbacks) vs. STL – 1.5 Hits (Over +175 / Under -242)
- JJ Wetherholt (St. Louis Cardinals) vs. AZ – 1.5 Hits (Over +175 / Under -242)
- Jordan Walker (St. Louis Cardinals) vs. AZ – 1.5 Hits (Over +170 / Under -231)
- Logan Gilbert (Seattle Mariners) vs. SF – 6.5 Strikeouts (Over -110 / Under -117)
- Casey Mize (Detroit Tigers) vs. LAA – 5.5 Strikeouts (Over -132 / Under +102)
When we are putting these entries to work, you have to look closely at the recent trends. I am looking hard at fading Riley Greene on that 1.5 hit line. He faces an uphill battle, averaging just over one hit per game this season. Ketel Marte is in a similar spot. Even though he has racked up 98 hits this season, he has fallen short of 1.5 hits in three of his last four home games at Chase Field.
On the mound, I absolutely love Logan Gilbert tonight. The Mariners’ starter has been electric, sporting a 3.316 ERA, an elite 0.9912 WHIP, and a 9.395 K/9 rate. He is trending heavily toward the over on his 6.5 strikeout line, having eclipsed that mark in four of his last five outings. On the flip side, Casey Mize has shown a massive under trend.
How to Use the Underdog Promo Code
Claiming your bonus entries and getting in on tonight’s MLB action is a breeze. Let’s walk through the steps together to make sure you get that reward:
- Register Your Account: Create a new account here. You will need to provide standard personal information to verify your identity.

- Make a Deposit: Fund your account by depositing at least $5 using one of Underdog’s secure payment methods.
- Play Your First Entry: Submit a $5 entry on the platform. The moment that entry is placed, your account will instantly be credited with $50 in bonus entries.
Building Your Entries
When constructing your $5 qualifying entry—or when deploying your newly acquired $50 in bonus entries—Underdog offers two primary ways to play:
- Standard Entry: For example, we could pair a strikeout prop from the 08:10 PM UTC matchup between the San Francisco Giants (42-56) and Seattle Mariners (49-50) with a batter prop from the 11:20 PM UTC clash between the Los Angeles Dodgers (62-36) and New York Yankees (54-43). Standard entries give us the largest potential payout, but keep in mind that all legs must hit for the entry to win.
- Flex Entry: If you like having a little safety net, try a “flex” entry. While the maximum payout is slightly reduced compared to a Standard play, a Flex entry allows you to still collect some winnings even if one of your selected legs is incorrect. It is a great strategy when you want to chase a bigger payout but still want some insurance if the game doesn’t go exactly to script.
