Ian Poulter has withdrawn from Monday's U.S. Open qualifier in Memphis as he looks to avoid playing "too much golf".

World number 81 Poulter has played six tournaments in seven weeks but must now rely on a rankings boost if he is to make it to Erin Hills.

Poulter needs a high finish at next week's FedEX St Jude Classic to secure the top-60 ranking that will secure his place in the U.S. Open.

Failure to qualify for the second major of the year would see Poulter switch his attention to a bid to reach The Open at Royal Birkdale in July.

"I felt it might be just a little bit too much golf," Poulter said of his decision to withdraw from the qualifier.

"A 36-hole qualifier on Monday in Memphis could be a little much leading in."

The U.S. Open gets under way in Erin, Wisconsin, on June 15.
