Middlesbrough enter the EFL Championship playoff semi-final first leg at Riverside Stadium as trader consensus slight favorites at 41.5% implied probability, buoyed by home advantage and a commanding 4-0 victory over Southampton in their January home league clash. Both sides clinched top-six finishes amid final-day drama, with Boro drawing Wrexham to secure fourth place ahead of Saints in fifth, setting up this promotion decider. Defensive injury concerns linger for Middlesbrough (Darragh Lenihan, Alfie Jones out long-term) and Southampton (Toby Harwood-Bellis ankle, Jan Bednarek knee doubts), potentially tightening defenses in a high-stakes tie. Recent form shows both competitive in the table race, but Boro's strong home record edges the closely contested market, where Saints (29.5%) and draw (28.5%) reflect upset potential.
