Five-time Grand Slam champion Iga Swiatek accepts a one-month suspension in doping case

Five-time Grand Slam champion Iga Swiatek accepted a one-month suspension after testing positive for the banned substance trimetazidine, a heart medication known as TMZ, the International Tennis Integrity Agency announced Thursday. Poland's Iga Swiatek reacts during her match against Italy's Jasmine Paolini Swiatek failed an out-of-competition drug test in August, and the ITIA accepted her explanation that the result was unintentional and was caused by the contamination of a nonprescription medication, melatonin, that Swiatek was taking for issues with jet lag and sleeping. This is the second recent high-profile doping case in tennis: The top-ranked man, Jannik Sinner, failed two tests for a steroid in March and was cleared in August, right before the start of the U.S. Open, which he went on to win for his second Grand Slam title of the season. She already was provisionally suspended from Sept. 22 to Oct. 4, missing three tournaments during the post-U.S. Open hard-court swing in Asia — the Korea Open, the China Open and the Wuhan Open.
