Ian Poulter was left unhappy that he was twice warned about slow play during his Masters second round on Friday.

The Englishman was twice 'put on the clock' at Augusta National - meaning he was being monitored for taking too long with his shots, and risked being penalised if he continued to play slowly.

Poulter came out fighting, claiming that his second round pairings - Trevor Immelman and Patrick Cantlay - were more responsible for the sluggish pace than he was.

Poulter told reporters: 'Listen, I don't care if I'm on the clock. It doesn't bother me. It's not, it's never going to affect my golf, so I'm fine. I know I'm quick enough. That's all I'm saying.

'I think as a group we were slow, but I'm not going to say the reasons why we were slow. I'm going to say "we". Let me just generalise and say "we". Just to keep that clean.

'I'm quite comfortable being on the clock every single shot. I'm not going to call foul. Unless you stand on the 12th and 11th and you get a big wind switch, that's when it's going to get tricky.

'So I mentioned to the lads, we need to get off this clock coming up 12 - and we did - but quite quickly we fell back on the clock. So we rightly should have been back on it.

'We have to be on the clock. We're too slow. When you're too slow, you need to speed up, end of conversation. If we're slow.'

Despite the slow pace, Poulter managed to narrowly make the cut with five over par after the second round.

Going into Sunday's final 18, he had got his score down to two over - but still 16 shots behind leader Patrick Reed.
