Mcdonald has won all 3 of their previous matches. Their last meeting was last week in the Charlottesville quarter final. He won on an indoor court in straight sets. He won all their matches in 2 sets.
On indoor courts this year they are quite evenly matched. Polansky reached the final in Knoxville in 2013.
Polansky lost the opening set to Dan Evans yesterday but fought back to take set 2 in a tbreak. He easily won the deciding set.
Mcdonald looked pretty comfortable in both his matches this week.
I can see this going to 3 sets. Back Mcdonald if he faces break point.
