The second round of the 2019 U.S. Open will be crucial for some players to improve their positioning ahead of the weekend.
Justin Rose is in the best shape of the 156 golfers in the field, as he holds a one-shot advantage over a collection of players in second place.
If you look further down the leaderboard, there are plenty of experienced players that could make a second-round surge, including two-time defending champion Brooks Koepka, who did just that a year ago.
There are also some high-profile players that need to make improvements from Thursday's first round in order to have a chance of being in contention for the title Saturday and Sunday.
