Girls 400mH
When: Sunday
Who: Sydney McLaughlin (NJ), Imagine Patterson (SC), Lauren Hoffman (Va.), Emily Sloan (CO)
Skinny: Will McLaughlin lower her world junior record in the 400mH? She ran 54.03 seconds at the NJSIAA Group Championships and has a chance to cut into that performance here. But don't forget about Hoffman, who's US No. 2 at 59.05 seconds and Patterson, who's looking to break 60 seconds.
