It’s a good semifinalist line-up Saturday in Stockholm with former champion Grigor Dimitrov taking on Juan Martin del Potro and then youngsters Jack Sock and Alexander Zverev lock up.
Dimitrov continued his strong second half of 2016 edging Kevin Anderson in three sets while del Potro dominated fellow big man Ivo Karlovic 6-3, 6-4.
“I was expecting a tie-break in this match,” said del Potro. “But I’m happy to get the rest for tomorrow when I play Grigor.”
Dimitrov actually served for the match against the South African 5-3 in the second before hanging on to win in three 7-6(3), 5-7, 6-2.
“It’s never easy when you serve for the match and you lose it,” said Dimitrov. “There was some very poor serving form me today, that’s all I can say. I know Kevin was stepping in on pretty much everything, so the match could have gone either way.”
Del Potro has won all three meetings against the Bulgarian most recently this June in Stuttgart.
Zverev and Sock advanced with straight set wins over Tobias Kamke and Gastao Elias, respectively. Zverev took the lone meeting with Sock in Beijing a few weeks ago.
In Moscow, the semifinals put Philipp Kohlschreiber against Fabio Fognini followed by Pablo Carreno Busta vs. Stephane Robert.
And in Antwerp, Kyle Edmund is into his first ATP semifinal after beating Andreas Seppi. He’ll take on Richard Gasquet. David Goffin will face Diego Schwartzman in the later semifinal.
