Olazabal appoints three Ryder Cup vice-captains

European Ryder Cup captain Jose Maria Olazabal has named experienced players Thomas Bjorn, Darren Clarke and Paul McGinley as three of his four vice-captains for next month's title defense against the United States.

Olazabal will announce his final vice-captain as well as his two wildcard player selections on Aug 27 for the 12-man team ahead of the Sept 28-30 matchplay competition at Medinah, Illinois.

"My own experiences as a vice-captain in 2008 and 2010 taught me that you need a lot of help that week," the Spaniard said on Thursday.
