Padres vs. Marlins — Polymarket Market Analysis (4:10 p.m. ET, FS1, loanDepot Park)
Buehler's contact-suppression profile against a Miami lineup playing at home gives this game clear structure on both the moneyline and totals markets. Junk has shown the ability to keep games close, and loanDepot Park's dimensions make the Under a natural lean when a quality arm is confirmed for the visiting side. Track the latest MLB odds alongside Polymarket contract prices — with starters already set, these numbers reflect more pre-game information than a typical same-day market.
Polymarket contract prices for Padres vs. Marlins:
| Outcome | Probability | Polymarket Price |
