Amanda Anisimova is back in a Grand Slam semifinal for the first time in over six years. On a tense Tuesday afternoon at Wimbledon’s No. 1 Court, the 23-year-old American nearly squandered a commanding second-set lead but held her nerve to defeat Russia’s Anastasia Pavlyuchenkova 6-1 7-6(9).

After failing to convert two match points at 5-4 and falling behind 3-6 in the tiebreak, Anisimova rallied, saving five set points and eventually sealing the win on her fourth match point with a powerful serve that Pavlyuchenkova returned into the net.
