Erin - Ryan Moore has withdrawn from the US Open with a shoulder injury that will keep him out for three to four weeks.
Moore was replaced by Michael Putnam, the first alternate from a 36-hole qualifier in Columbus, Ohio, and the odd man out in a 4-for-3 playoff on Tuesday morning.
In a coincidence, Moore and Putnam both grew up near Chambers Bay, site of the 2015 US Open.
The US Open starts on June 15 at Erin Hills.
Jeremy Moore, his brother and manager, said on Wednesday that while the strained shoulder is a minor injury, Moore's doctor recommended he take time off to let it heal.
He is expected back at full health.
Putnam hit the opening shot in the US Open at Chambers Bay.
This will be his fourth US Open.
