[U.S. OPEN CUP]The Tampa Bay Rowdies and Carolina RailHawks from the NASL and Orlando City and Charleston Battery from USL PRO will look to extend their run in the centennial edition of the of the U.S. Open Cup with wins over MLS clubs in four-round play on Wednesday.
-- Orlando City has probably the toughest task, taking on its MLS affiliate Sporting Kansas City without Dom Dwyer, who has already broken the USL PRO single-season scoring record, and its other loan players.
-- For the second straight year, Carolina plays Chivas USA in the fourth round after beating the LA Galaxy in the third round. In 2012, Chivas USA knocked the RailHawks out of the competition on a Juan Pablo Angel penalty kick in stoppage time.
-- Charleston looks to advance to the quarterfinals for the eighth time. It finished as the runner-up in 2008, made the semifinals in 1999 and 2004 and reaching the final eight in 2007, 2009 and 2010.
-- The Rowdies are short-handed for their trip to Portland without injured Takuya Yamada and Daniel Scott, and Jordan Gafa, who was red-carded in the 1-0 win over Seattle.
