Trading on MLB Saturday

Trading your $20 bonus on a heavy favorite's moneyline will yield a smaller, safer return. However, if we identify a live underdog on the board, placing that same $20 gives us a real chance at a much larger, lucrative payout.

Proper handicapping is key, so let's look at the numbers. The Pirates (PIT) head into Los Angeles with serious underdog energy to face a Dodgers (LAD) team expecting an easy sweep behind a rotation featuring Tarik Skubal and Yoshinobu Yamamoto. The Dodgers boast a 3.703 team ERA and a .765 OPS, scoring 640 runs. The Pirates trail slightly on the mound with a 4.294 ERA, though they have a .744 OPS and have plated 646 runs.

Out in Seattle, the Mariners (SEA) are calling up top pitching prospect Kade Anderson for his MLB debut to spark an offense that has struggled to just 500 runs and a .685 OPS. They host a Cubs (CHC) squad fresh off some viral bleacher brawls back home, bringing a potent offense (656 runs, .755 OPS) against Seattle's 4.002 staff ERA. Reviewing these metrics gives us a solid edge once the numbers go live.
