Serena Williams was 17 when she won her first Grand Slam singles title in 1999 at the United States Open.
On Saturday, in the same stadium, she will try to prevent another fast-rising teenager — 19-year-old Bianca Andreescu — from winning her first major and thwarting Williams’s latest attempt to acquire a record-tying 24th.
Not a bad story line, but what makes it better is that the 15th-seeded Andreescu, despite her inexperience at this pressurized level of a Grand Slam tournament, has the weapons, maturity and moxie to potentially make this final a terrific match.
