The price says this is settled, and the reasons hold up. This is an M25 Yinchuan semifinal, and Chen is an 18-year-old lefty from Chinese Taipei sitting around 2,211 in the ATP rankings with a career-high ITF junior mark of 13. That pedigree at this level explains the gap. Binda getting a fifth of the market isn't nothing at Futures, where a single break decides sets and the favorite is a teenager still building a senior body. The volume, over a million on each side, is heavy for a match this obscure, so treat sharp late money as more informative than the opening number here.
