How to Use Your Underdog MLB Promo Tonight

Once you have secured those bonus entries, it is time to start analyzing the board. If you want to move beyond simple picks and build a more sophisticated card for a bigger payout, here is exactly what I am looking at. I have pulled the eight players with the highest heavily-favored hit lines on tonight’s slate, plus two notable pitcher strikeout projections we can target:

• Fernando Tatis Jr. (San Diego Padres at Atlanta Braves): 1.5 Hits
• Drake Baldwin (Atlanta Braves vs. San Diego Padres): 0.5 Hits
• Ty France (San Diego Padres at Atlanta Braves): 0.5 Hits
• Kevin McGonigle (Detroit Tigers at Chicago Cubs): 0.5 Hits
• Nico Hoerner (Chicago Cubs vs. Detroit Tigers): 0.5 Hits
• Pete Crow-Armstrong (Chicago Cubs vs. Detroit Tigers): 0.5 Hits
• Manny Machado (San Diego Padres at Atlanta Braves): 0.5 Hits
• Dillon Dingler (Detroit Tigers at Chicago Cubs): 0.5 Hits
• Michael King (San Diego Padres at Atlanta Braves): 4.5 Strikeouts
• Colin Rea (Chicago Cubs vs. Detroit Tigers): 4.5 Strikeouts

Now, let’s talk strategy. With our bonus entries locked and loaded, the board offers plenty of compelling matchups. I am definitely eyeing Fernando Tatis Jr.—he is the lone batter featured with a 1.5 total hits line. He draws a great matchup against veteran Braves starter Martín Pérez, who enters the contest with a 3.75 ERA and a 1.27 WHIP. Manny Machado also profiles beautifully to secure at least one hit and keep the Padres’ offense moving.

On the pitching side, Michael King boasts an over/under of 4.5 strikeouts against the Braves. King brings a sharp 3.33 ERA and 1.15 WHIP across 113.1 innings. I am keying him as a prime candidate for a strikeout-based prop.

Looking at the Cubs and Tigers matchup, Chicago’s lineup features reliable contact guys like Nico Hoerner and Pete Crow-Armstrong facing Tigers starter Keider Montero. Montero holds a solid 3.33 ERA, but these bats have hit lines heavily shaded toward the over. For the Cubs’ pitching, Colin Rea holds a 4.5 strikeout line as he navigates a Detroit order anchored by Kevin McGonigle and Dillon Dingler. We have plenty of ways to build a winning card tonight.

Ready to build these cards with me? Claiming your $50 in bonus entries takes just a few straightforward steps. Here is how we get started:

1. Sign Up: Create and register a new account with Underdog. You will need to provide standard personal information to verify your identity.

Once your account is loaded and your bonus entries are ready, we have two primary options when building our props:

• Standard Entry: Select 2+ picks. This format triggers the largest potential payout, but keep in mind that all legs must hit for your entry to win.
• Flex Entry: Select 3+ picks. This format is a great strategy if you want a safety net. It allows you to still receive some winnings even if one of the legs on your card is incorrect.
