Female Tennis Player, US Open 2011

In 2007, JP Morgan Chase renewed its sponsorship of the US Open. As part of its sponsorship arrangement, Chase renamed the tournament's replay system the "Chase Review" on in-stadium video and television.
Grounds
The DecoTurf surface at the US Open is a fast surface, having slightly less friction and producing a lower bounce compared to other hard courts (most notably the Rebound Ace surface formerly used at the Australian Open). For this reason, many serve-and-volley players have found success at the US Open.
