LONDON — American Varvara Lepchenko tested positive four times for meldonium, according to the International Tennis Federation, which cleared her because it was determined she took the substance before its ban went into effect on Jan. 1.
The ITF announced Tuesday that Lepchenko had been provisionally suspended in March but it was later determined that she “bore no fault or negligence for the violation.”
Meldonium, also known as mildronate, is the same substance for which Maria Sharapova tested positive, drawing a two-year ban that she has appealed. She acknowledged taking the drug in January.
The Latvian-made drug is typically used for heart conditions.
The ITF said meldonium was in Lepchenko’s system in decreasing amounts on Jan. 7, Feb. 1, March 1 and April 7. She appealed her provisional suspension, saying she had last taken mildronate tablets “on or around” Dec. 20.
The 30-year-old Lepchenko, who was born in Uzbekistan, is No. 79 in this week’s WTA rankings.
TOKYO — Wimbledon champion Garbine Muguruza advanced to the semifinals of the Pan Pacific Open by beating Caroline Garcia 6-2, 6-4 Friday.
A rare double-fault by the top-seeded Muguruza allowed Garcia to pull even at 3-3 in the second set, but the Spaniard broke back in the next game.
Playing in her first tournament since earning the No. 1 ranking, Muguruza will next face Caroline Wozniacki. The former top-ranked Dane advanced when Dominika Cibulkova was forced to retire with a right thigh injury while trailing 3-6, 7-6 (5), 3-1.
Also, Angelique Kerber upset second-seeded Karolina Pliskova 7-6 (5), 7-5. The seventh-seeded Kerber took advantage of several unforced errors by the Czech player and won with a powerful cross-court shot on her fifth match point.
Kerber will face Anastasia Pavlyuchenkova in the semifinals. The Russian beat Barbora Strycova 5-7, 6-3, 6-1.
METZ, France — French player Benoit Paire came out on top of a tight battle with David Goffin to reach the semifinals of the Moselle Open on Friday after saving one match point.
Paire edged the 2014 champion 7-6 (3), 5-7, 7-6 (7) after nearly 2 1/2 hours at the indoor tournament.
Goffin led 4-2 in the decider and failed to convert a match point at 6-5 in the tiebreaker.
Paire will next be up against Nikoloz Basilashvili of Georgia.
The other semifinal will pit Mischa Zverev against qualifier Peter Gojowczyk.
The fifth-seeded Zverev defeated lucky loser Kenny de Schepper 7-5, 7-6 (4) while the 95th-ranked Gojowczyk needed less than one hour to beat Marius Copil 6-2, 6-4.
