SHANGHAI — Nick Kyrgios is toeing the line on the tennis court these days, and he knows it.
The emotional Australian was placed on probation by the ATP Tour for derogatory comments he made to Stan Wawrinka during a match in August and warned he would face a 28-day suspension if he totaled more than $5,000 in fines before February.
Three days into the Shanghai Masters, he's already been fined $1,500 for an "audible obscenity" and received a code violation for unsportsmanlike conduct for smacking a ball toward a line judge in frustration.
Kyrgios said after his loss to Kei Nishikori on Wednesday that he's trying to keep his emotions in check, but he's not thinking about the looming suspension.
