Alejandro Davidovich Fokina and Alexander Zverev meet in the semifinal at Shanghai on Saturday. Alexander Zverev has won 4 in a row and 8 of the last 10 overall. Alejandro Davidovich Fokina brings a 3-match winning streak into this one, 8-2 across the last ten.
Zverev's 73.7% behind the first serve (against 67.3% for Fokina) means break chances should be scarce in one direction. Zverev should have enough here, though Fokina has the tools to make the scoreboard uncomfortable.
