SAO PAULO — Jurgen Klinsmann is optimistic forward Jozy Altidore will return for the U.S. during this World Cup. Altidore underwent an MRI exam on his injured left hamstring Tuesday after the U.S. squad returned to its Sao Paulo headquarters from Monday night's 2-1 victory against Ghana. Results weren't immediately available, and there is some doubt because hamstrings aren't always quick to heal.
