Overnight leader Paul Casey held a share of the early clubhouse lead on day two of the Porsche European Open after following up Thursday's 66 with a battling 73.
Casey recovered from a rocky start to his second round - which saw him drop three shots in his first five holes - after carding three birdies and just one more bogey to head into the weekend on five under par.
The 42-year-old was joined on that mark by Matthias Schwab after the Austrian cancelled out a front nine bogey with a birdie at the long 15th to sign for a 72.
But the pair had to settle for a share of second as afternoon starter Robert MacIntyre fired birdies at the third to grab the outright lead on six under.
Ryder Cup star Casey came into the second round with a one shot lead over Schwab after posting a highly impressive 66 on a tricky first day at Green Eagle Golf Courses.
But he could not keep that momentum going as the course showed its teeth on Friday morning, slipping off the summit after carding bogeys at the tenth, 13th and 14th.
Casey bounced back with a birdie on the 15th before closing his front nine with another gain at the par five 18th.
The Englishman dropped a shot at the third after his lengthy birdie putt slid 12 feet past the hole.
But after making a good up-and-down from the bank behind the fourth green for a solid par, Casey took advantage of the short fifth with a wonderful birdie putt from ten feet to return to five under.
And after playing a good recovery shot from the waste area at the sixth on his way to saving his par, he safely parred the seventh, eighth and ninth to sign for a 73.
After his round, Casey said: "I'm quite happy to be standing here with one over - five under for the tournament.
"It's such a difficult golf course. Attitude is key and I had a good attitude.
"Luckily there are some options to get birdies if you stick with it and you hit good golf shots and luckily I made a couple but yeah, very difficult stuff."
Schwab reached the turn in 35 after dropping his only shot of the day on the seventh.
And he parred his way to the 15th before making a birdie there to join Casey in the clubhouse on five under.
