The Englishman will make his fifth U.S. Open start as a result of being inside the top 60 of the Official World Golf Ranking as of May 24. Wallace owns four European Tour victories, the last coming in the 2018 Made in Denmark. Prior to joining the European Tour, he won six times on the Alps Tour in 2016 to win the Order of Merit. This enabled the Englishman to join the European Challenge Tour in 2017. He secured his European Tour privileges in May 2017 by claiming the Open de Portugal by three strokes over Julian Suri.
