Munster opened their 2020–21 Pro14 season with a 30–27 away win against Scarlets on 3 October 2020. Despite nine penalties from Scarlets fullback Leigh Halfpenny and a red card for captain Peter O'Mahony, tries from Jack O'Donoghue and Chris Farrell kept Munster within touching distance of the hosts, and a try from replacement hooker Kevin O'Byrne, converted by Ben Healy, levelled the score going into the final minutes of the game, before academy fly-half Healy scored a 50-metre penalty in the 81st minute to earn what had previously looked like an unlikely win for the province.
