SAN FRANCISCO (AP) — British Olympic star Ben Ainslie is serving as tactician with Oracle Team USA's main crew on a training run on San Francisco Bay as the syndicate seeks changes to turn around its America's Cup misfortunes.
Ainslie replaced John Kostecki for Wednesday's training session.
The syndicate hasn't confirmed if Ainslie will be on the boat Thursday for Races 6 and 7.
Kostecki called for a foiling tack that resulted in a colossal blunder that led to a crushing loss to Emirates Team New Zealand in Race 5 on Tuesday. The Kiwis lead 4 to minus-1 and need five wins to claim the oldest trophy in international sports.
Ainslie, who won four straight Olympic gold medals and has five games medals total, has been helmsman of Oracle's B boat.
