“The most riveting episode in sports history.” That’s what ESPN called what played out in the fourth-set tie-breaker waged between unkempt tennis legends Bjorn Borg and John McEnroe in their historic 1980 gentlemen’s singles final at Wimbledon. On Saturday night at Toronto’s Commerce Court, performance artists (and spry tennis players) Tibi Tibi Neuspiel and Geoffrey Pugen will replay that tie-breaking thriller every hour as part of the city’s all-night art blast Nuit Blanche—wooden rackets, headbands, naked emotion and all. Amazingly, these guys, who bear a resemblance to the court heroes of yore, will attempt to recreate each point of the tie-break stroke by stroke.
