Padraig Harrington says he will "play hard" to make sure he returns to Europe's Ryder Cup side at Gleneagles in 2014.
Ireland's three-major winner failed to receive a wild card from Jose Maria Olazabal on Monday and so will not be part of the match for the first time since 1997.
"I've been aware of the Ryder Cup situation since the PGA Championship and I pretty much knew the outcome," Harrington said on his website.
"Ollie called me to let me know. The Ryder Cup is a team event and you should qualify by merit.
"I thoroughly believe the two picks (Ian Poulter and uncapped Belgian Nicolas Colsaerts) will deliver and do a good job.
"I will be watching and rooting for the team and I wish them well."
