Step 1 : Introduction to the question "Which tennis star was stabbed by a deranged man during a match in 1993?"
...On this day in 1993, top women’s tennis player Monica Seles was stabbed by a deranged German man during a match in Hamburg, Germany. The assailant, a fan of German tennis star Steffi Graf, apparently hoped that by injuring Seles his idol Steffi Graf would be able to regain her No. 1 ranking. Seles became a victim of the on-court attack when 38-year-old Gunter Parche leaned over a fence and stabbed her between the shoulder blades with a 9-inch long knife. Parche was quickly apprehended and Seles was taken to the hospital. She didn’t play again professionally for another two years.
