( CNN ) -- After winning the BMW PGA Championship in England in late May , Rory McIlroy missed the cut at his next European event , the Irish Open , last month . The Scottish Open is mirroring the former No . 1 's inconsistent season . McIlroy produced a superb , course-record 64 in chilly , windy conditions at Royal Aberdeen on Thursday -- it included a staggering 430-yard drive -- but then imploded Friday , registering a 7-over-par 78 . He is six shots behind leaders Kristoffer Broberg , Marc Warren and Ricardo Gonzalez . It was one of the biggest turnarounds you 're bound to see -- but in keeping with his second-round woes . At 13 stroke-play events this season , he has failed to hit under 70 in the second round nine times and his average stands at 72.2 , noted the Golf Channel . `` I 'd be much happier standing here after a couple of 71s , but that 's not the case , '' McIlroy told reporters . `` It has n't been the case all year . `` I get off to a good start and then I just fall away . But I 'm still in the tournament and I can go out in the morning and try and get a few of those shots back that I lost today . `` I need to try and hold it together somewhat . McIlroy 's front nine , though not good , was n't terrible . He mixed three bogeys with one birdie . But on the back nine he did n't hit a birdie and struck a double bogey and three bogeys . From being in an outstanding position Thursday , he was n't far off missing another cut . It 's not the round he would have wanted with the British Open taking place next week . `` It 's another Friday out of the way , '' McIlroy said . `` Now I can go onto the weekend . '' Phil Mickelson , the other marquee name at the event , dipped , too . Last year 's Scottish and British Open winner was five shots worse in the second round , carding a 73 . `` I 'm a little concerned that it 's taking up a little more energy than I would like for next week , but it 's also a good opportunity to focus on some of the difficult shots that we 'll have next week , so it kind of goes both ways , '' Mickelson said in a TV interview shown by Sky . Mickelson is five shots off the pace . Wie misses cut . It wo n't be two majors in a row for Michelle Wie . Wie , the much hyped American , missed the cut at the women 's British Open at Royal Birkdale in Southport , England less than a month after claiming her first major , the U.S. Open . The 24-year-old followed up her 75 Thursday with a 78 Friday , undone by six birdies and a double bogey . `` I missed a lot of greens , '' Wie , who turned pro aged 15 , told reporters . `` I had a lot of hard par putts today , and I did n't make them . I did n't do much on any of the holes . It did n't go quite as well as I wanted it to . '' Another American , Mo Martin , leads at the halfway stage by three shots over Spain 's Beatriz Recari . Overnight leader Ayako Uehara crashed to a 79 and trails Martin by nine shots .
After his course record 64 Thursday , Rory McIlroy slumps at the Scottish Open . McIlroy shoots a 78 at Royal Aberdeen that included a double bogey on back nine . Phil Mickelson also dipped though not as much , going from a 68 to 73 . Michelle Wie misses the cut at the women 's British Open at Royal Birkdale .
