Scotland's Robert MacIntyre is in pole position to cap a brilliant rookie season with a maiden European Tour title after finding top gear in the Porsche European Open.

MacIntyre added a flawless second round of 65 to his opening 68 at Green Eagle Golf Course in Hamburg to reach 11 under par, four shots clear of Germany's Bernd Ritthammer, who returned a 66.

Overnight leader Paul Casey struggled to a 73 to lie six shots off the pace alongside Austria's Matthias Schwab and Italy's Guido Migliozzi.

MacIntyre's brilliant debut season has already produced back-to-back runners-up finishes and a tie for sixth in the Open at Royal Portrush.

Of the Irish, Michael Hoey (+1), Padraig Harrington (+1) and Gavin Moynihan (+2+ all made the cut, but Cormac Sharvin misses out on +6.
