Thiem was a bad matchup for Federer in his mid-late 30s. When he was an underdog without the expectation to win, he managed to push Djokovic to 5 sets at AO, so he would’ve given Fed a tough fight there.
Also, Federer was pretty inconsistent at USO in his 30s, I wouldn’t be surprised if he got upset early, especially at age 39.
