Bianca Andreescu survives Serena William's comeback attempt to win her first career Grand Slam championship 6-3, 7-5. (2:35)

The 2019 US Open women's singles final between Bianca Andreescu and Serena Williams on Saturday had a little bit of everything. History was on the line for both players -- Andreescu was trying to become the first Canadian to win a Grand Slam title, and Serena was vying for a record-tying 24th Slam title.

After Serena tried to make a fantastic comeback in the second set, the 19-year-old Canadian won on her third championship point to beat Williams 6-3, 7-5. Here is how the Twitterverse reacted.
