Back on the Korn Ferry Tour in 2020, Jäger picked up his fifth title on the tour at the Albertsons Boise Open. The win helped gain him exemption into the 2020 U.S. Open as one of the leading points scorers in the final three Championship Series events, and into four alternate events on the PGA Tour in 2021 by virtue of being in the top ten of the tour standings after the Korn Ferry Tour Championship.
