Rory McIlroy was faced with an uphill task on day two of the Masters after England’s Paul Casey set an impressive clubhouse target at Augusta National.

Casey fired an eagle and five birdies in a flawless 65 to lead by two shots from Webb Simpson and Xander Schauffele, with defending champion Tiger Woods and Lee Westwood part of a five-strong group on four under.

A weather delay of almost three hours meant most of the later starters were unable to finish their first round on schedule, with Justin Thomas reaching five under par after 10 holes before play was suspended due to the fading light.

McIlroy had covered the front nine in level par and faced a bunker shot on the 10th when play resumed.
