KEY BISCAYNE, Fla. (AP) – For Roger Federer and Rafael Nadal, it was a happy anniversary.
For Stan Wawrinka, it was not a happy birthday.
Federer and Nadal – playing back-to-back on stadium court on the 13th anniversary of their very first match – both advanced Tuesday to the quarterfinals of the Miami Open.
Wawrinka wasn’t as fortunate, the No. 1 seed getting bounced on his 32nd birthday by teenager Alexander Zverev.
