Joost said he round was good, and the rough meant you had to play smart golf; "It was good “I hit some nice shots in close for birdie. I didn’t make as many putts as yesterday but I’m really happy with the score. On this course you know you’re going to make a few bogeys but there are a lot of chances for birdie as well. You just have to try to stay patient and I think I did that well today. The greens are great, maybe the best of the season. They've had a lot of rain but they’re still probably the best greens we've played on this year. They hold the shots going in and they are quick. What a good job they've done here. You have to play smart on some holes and it’s playing long, the rough is very tough." There are three players tied in second place at -10 under par, Paul Waring, Callum Macaulay and Eduardo De La Riva. Spaniard Eduardo is a Qualifying School graduate, and started his second round with an eagle at the long tenth, and finished it with five birdies in his last seven holes which propelled him into contention. Eduardo was very happy with his round and his putting; " Five birdies in the last few holes is very good, and the last two holes were only from a couple of inches. I've played very good in some tournaments but I've had some problems with my putter. With some good work it’s better, today I putted very well and I’m very happy." Paul was also happy, especially as his wrist problems have gone away; "I'm very happy, I finished a little bit poorly but I played awful the last few weeks to be honest so it's nice to feel I have got my swing back where it needs to be. I did a lot of work after missing the cut in Sweden and because I know the course here I even had Tuesday at home practising before flying out. The wrist is absolutely fine now, nothing to worry about, which is nice. I can go and play golf and practise as much as I want and we are starting to see some results out of it." Cullum has his brother on the bag this week, and it appears to have been a good selection; “It’s unchartered waters for the last two or three years, and if I’m being honest it’s come out of nowhere. I’ve had a really poor start to the season and I’ve worked exceptionally hard to improve, but things haven’t been going my way. I did a lot of work last weekend in Sweden with Scott Arnold, who also missed the cut, and he made a couple of suggestions. It was very simple, I was de-lofting my irons on the way back and not getting any height. It’s taken a lot of repetition and it still feels a little bit funny, but I just need to keep hitting balls and get more comfortable. This sport can change in a heartbeat and you have to keep plodding along hoping things will turn. This is a big step in the right direction. I’ve got my brother caddying for me this week and he’s always pretty cool no matter what. It’ll be new for me playing in the last few groups in a European Tour event, but that’s why we play the game. We want to get better every week."
