2020 saw the Saints reach finals for the first time since 2011, and Battle played a big part in a Covid-interrupted season. Battle was unable to break into the side early in the season, with new defender Dougal Howard cementing a place in defence. Battle was called up in round four and played four straight games, including three wins. Battle suffered a concussion following the round seven win over Adelaide. He returned the week later, and played nine consequitve games before a foot injury ruled him out of the Saints' elimination final. Battle recovered and played his first AFL final in the Saints' Semi Final loss to eventual premiers Richmond. He ultimately played 14 of a possible 19 games that year.
