Justin Rose went low over the first 18 holes at the 2021 Masters and sat four shots clear of the field at 7 under before Friday's Round 2 got underway. The Augusta National course has been firm and fast, creating problems for most star golfers in the field, but Rose was completely unaffected by shooting 6 under on the second nine to bounce back from an uneven start.

As for whether anyone will actually catch Rose, that remains to be seen. Brian Harman and Hideki Matsuyama both sit at 3 under, but less than 15% of the field is below even after 18 holes. That gives Rose a clear advantage as he looks to grow his lead and others try to avoid missing the cut at the first major tournament of 2021.

With one quarter of the championship in the books, attention now firmly turns to Friday's second round. There's plenty of intrigue in the middle of the pack, including from Jordan Spieth, who shot a triple bogey on Thursday but nevertheless remains in the top 10 entering his second 18 holes thanks to a steady hand on the second nine. Perhaps he will make a Day 2 run and go after back-to-back events following his Texas Open win last week.
