How to Use Your Underdog MLB Promo Tonight
Once you claim your bonus entries, it is time to dig into the data and build your slip. Underdog offers a massive variety of player projections to choose from, spanning standard hit lines to strikeout totals for starting pitchers.
If you are looking for a baseline for tonight’s slate, here are eight of the highest hit projections and two notable pitcher strikeout projections currently available:
- Ceddanne Rafaela (Boston Red Sox vs. Baltimore Orioles): 1.5 Hits
- Fernando Tatis Jr. (San Diego Padres vs. Atlanta Braves): 1.5 Hits
- Michael Harris II (Atlanta Braves vs. San Diego Padres): 1.5 Hits
- Drake Baldwin (Atlanta Braves vs. San Diego Padres): 1.5 Hits
- Ben Rice (New York Yankees vs. Pittsburgh Pirates): 0.5 Hits
- Jackson Merrill (San Diego Padres vs. Atlanta Braves): 0.5 Hits
- Wilyer Abreu (Boston Red Sox vs. Baltimore Orioles): 0.5 Hits
- Will Warren (New York Yankees vs. Pittsburgh Pirates): 5.5 Strikeouts
- Walker Buehler (San Diego Padres vs. Atlanta Braves): 3.5 Strikeouts
With several high-powered offenses in action, it does stand to reason that we are seeing elevated 1.5 hit lines across the board. The Atlanta Braves boast two players—Michael Harris II and Drake Baldwin—tasked with multi-hit expectations as they host San Diego. On the other side of that exact same matchup, Padres superstar Fernando Tatis Jr. is also carrying a 1.5 hit line, making him a primary target for those piecing together correlated entries.
Meanwhile, Pittsburgh’s Jake Mangum and Boston’s Ceddanne Rafaela find themselves in a similar position with 1.5 hit totals for their respective games. If you prefer targeting pitching props and searching for market inefficiencies there, Yankees starter Will Warren has a relatively balanced 5.5 strikeout line against the Pirates, while San Diego’s Walker Buehler enters his start against the Braves with a 3.5 strikeout projection. Mixing and matching these heavy-hitters and strikeout targets is a savvy, analytical way to put your Underdog bonus entries into play.
