Schotter Robert MacIntyre shot a second-round seven-under-par 65 to get a four-shot lead over the Porsche European Open.

MacIntyre hit seven birdies without dropping a shot and is halfway at 11-under 133 overall.

Bernd Ritthammer of Germany is second after carding a six-under 66.

"It's probably the best I've driven a ball – possibly this year. It not only does it go straight, it goes for miles, "said MacIntyre, 23,

" I don't know what I do, but it works so I'm just trying to keep doing it. "

Paul Casey from England led after the first round, but a four-under 68 means he's six shots off the pace.

Casey is next to Italy Guido Migliozzi and Matthias Schwab of Austria on five under.
