Graeme McDowell ended what was still a big week for Shane Lowry at the Match Play Championship.

McDowell made three birdies in a five-hole stretch to build a 4-up lead at the turn and outlasted his Irish friend, 3 and 2, to reach the quarterfinals. Next up for McDowell is Jason Day, who eliminated Masters champion Bubba Watson and left this event without a top 10 seed going into the final 8 for the first time in its 15-year history.

The best golf belonged to Steve Stricker, who celebrated his 46th birthday with a match that made him feel 47. He made eight birdies and needed every one to beat Scott Piercy, who shot 65 and lost. Stricker birdied the last two holes, making a 30-foot putt to win.
