Friday's Shanghai round of 64 pits Alexander Bublik against Tomas Machac on hard. Alexander Bublik limps in on a 3-match losing skid, just 5 wins in 10. Tomas Machac comes in at 4 wins from the last ten.

Bublik's 77.4% behind the first serve (against 68.6% for Machac) means break chances should be scarce in one direction. The edge belongs to Bublik — real, but not the kind you take for granted at this level.
