Summary

Sean Zerillo is a senior writer and betting analyst at the Action Network, providing projections for the company’s MLB and MMA verticals using his own proprietary data models.

Sean also provides digital content related to MLB, MMA and horse racing across all platforms. You can find him regularly on Payoff Pitch, Action Network’s MLB betting podcast, as well as The Action Network Podcast, where he’s a leading expert on UFC events, major horse races, and more.

Sean is a regular contributor to Green Dot Daily, Action Network’s daily (M-F) show that airs live at 3 p.m. ET on YouTube.

Experience

Sean began betting in 2007 when he first learned about Wong teasers. He previously followed a career path in the legal industry, but re-routed toward sports data and information in 2018.

Sean began contributing to the Action Network in 2019 after working as a baseball video scout for Sports Info Solutions. He previously worked in financial regulatory compliance, including sports at E-TRADE and RBC Capital Markets.

Since joining the Action Network, Sean has become one of the leading voices in the betting spaces of both baseball and MMA. 

Sean’s dedication to his craft is so prevalent that, when Major League Baseball was shut down during the global pandemic in 2020, he began successfully handicapping baseball games in Korea’s professional baseball league, the KBO.

Education

Sean graduated from the University of Miami with degrees in Sports Administration and Philosophy. He later attended law school at Hofstra University and passed the New York State Bar Exam in 2014.

Added 2/24. More awards bets unveiled next week but I expect this to move. Like to +1500 +3000 at Fanatics, +2000 at CZR Only 23 GP at Double-A but would have gotten September callup without injury. Angels had same aggressive promotion for Schanuel (17 games above A ball) and Neto (41 above A ball) Wash loves him: stories every day about them trying to find him a position plus Rendon + Moncada already hurt Most optimistic current projection has him at 280 PA; if he makes OD roster may double that

2025 MLB To Make the Playoffs
0.35u
Best value on the board before opening day - wanted to hit one more time. I make this -244 and I give CLE the highest chance of making the playoffs (29%) vs. public projections: PECOTA at 25%, FG 23.5%, ATC 20.7%, BAT 20.5%, OOPSY 15.4%; public consensus makes it -375 to miss

Seattle Mariners+400
2025 MLB AL West - To Win
0.25u
Bet to +325. Added 7/17. Avg. Projection: +266. Home series vs a banged up Astros team right out of the break

Seattle Mariners+1400
2025 MLB American League - To Win
0.1u
Bet to +1000. Added 7/17. Have Rays (+3000), Red Sox (+1400), Tigers (+1300) each at 0.1u from March so trying not to over-allocate but this is my favorite of the three bets on Seattle that I’m adding here and would increase to 0.25u if you aren’t building a portfolio

Seattle Mariners+3000
2025 MLB World Series - To Win
0.1u
Bet to +2000. Added 7/17. Avg. Projection +1595. Only team that is currently a consensus value futures bet and seem likely to flip prospects for impact hitter (hopefully Naylor) at deadline. Prefer Pennant to WS but laddering

Seattle Mariners+1100
2025 MLB American League - To Win
0.1u
Added 7/24 Wanted Naylor, got Naylor. Get Suarez too? Took +3000 WS and +1400 AL last week at AS break. Would take down to +2000 and +800 currently (projections around 5.5% and 12% respectively before the trade) Stake .2u on Pennant and .1 on WS if you didn't bet previously - just bumping here.
