Seles vs. Graf — A Rivalry Interrupted By an Attack That Changed Tennis

Before April 1993, this was one of the most competitive rivalries in women's tennis. Monica Seles had taken the world No. 1 ranking from Steffi Graf in March 1991 and won seven of nine Grand Slam titles across the following two years. Their head-to-head through that stretch sat at 6-4 in Graf's favor — close, active, genuinely contested. Then, on April 30, 1993, everything about this rivalry changed, for reasons that had nothing to do with tennis.

What happened in Hamburg

Seles was playing a quarterfinal match at the Rothenbaum Tennis Club, leading 4-3 in the second set after winning the first, when a man named Günter Parche approached her during a changeover and stabbed her in the back with a nine-inch knife. Parche was later found to have targeted Seles specifically because he wanted Graf to reclaim the world No. 1 ranking. Seles survived the physical injury, but she didn't play another competitive match for over two years.

A rivalry that resumed, but never the same way

Graf reclaimed the No. 1 ranking that June, with Seles out of the sport entirely. When Seles eventually returned, the two players met five more times between 1995 and 1999 — and Graf won four of them, giving Graf the full career head-to-head, 10-5 across 15 matches. But the pre- and post-1993 splits tell the real story: 6-4 in Graf's favor before the attack, 4-1 in Graf's favor after it. The rivalry didn't end in April 1993. It just stopped being a fair fight.

What it changed beyond the scoreline

The attack on Seles is widely credited with prompting real changes in how tournaments handle player security — a grim, lasting legacy that has nothing to do with either woman's tennis. It's impossible to say with certainty what the rest of this rivalry would have looked like without it. What's certain is that one of the most promising rivalries of its era was cut short by something that happened off the court entirely, and neither the sport nor the two players involved ever fully got that trajectory back.
