Maria Timofeeva and Tamara Zidansek meet in the first round at US Open on Monday. Tamara Zidansek limps in on a 2-match losing skid, just 5 wins in 10. Maria Timofeeva comes in at 8 wins from the last ten.

On paper it's close: comparable ratings, comparable serve numbers, small margins everywhere. This one is close to a coin flip, and the lean toward Zidansek is exactly that — a lean.
