It's nearly 8pm in Scotland right now and they are close to the midway point of the Open Championship.  With Tiger Woods not likely to be around on the weekend, a lot of fans are probably not going to watch the Open wondering what to watch for this weekend.

Let's break it down for you.

The final group is set - it's Steve Marino and Tom Watson.  Marino is playing in his first Open Championship and got into the tournament as an alternate after Shingo Katayama had to withdraw.  Tom Watson - you may have heard of him - has won five Open Championship (last in 1983), eight majors in total, and has won on this course previously. 

The dynamic for this group will be the recognition of the moment.  Watson said after Thursday's round that he did not know how he would respond to pressure on Friday.  His back nine proved that he could respond very well.  Marino will be under major pressure for the first time in his career.  Watson last sniffed the lead of a major at the 2003 US Open, but finished 12 shots off of the winning total of Jim Furyk.  How will each respond?

The 1989 Open Champion, Mark Calcavecchia, sits a shot off of the lead.  Calc's last PGA Tour win was at the Transitions Championship a few years ago.  He once held the 72 hole scoring record on Tour with his performance at the 2002 FBR Open.  But, in the 20 years since his Open breakthrough in a playoff, Calc has never finished in the top 10 and has missed the cut five times.

His play was much more unexpected than his likely playing partner on Saturday, Englishman Ross Fisher.  Fisher is having a career season.  He finished fifth at the US Open and had a runner up finish in the European Tour's BMW PGA Championship - their "fifth major."  Fisher's one Euro Tour win is the 2007 KLM Open.  He is playing in his third Open and finished T39 last year.

Aside from the final group, perhaps the most intriguing player in contention is Retief Goosen.  Known for his mental toughness, that appears to have slipped in the past few months.  The two-time US Open Champion has had a recent stint of leads on the European Tour that he has ceded in the final round.  Goosen lost the Scottish Open last week as much as Martin Kaymer (currently T14) won it.  He had a chance in Germany.  Curiously enough, Goosen won on the PGA Tour for the first time in four years when he took the Transitions Championship in March.    As far as the Open goes, Goosen has had an outside chance to win in 2005 at St. Andrew's but finished 5th with Tiger Woods as champion.

Other contenders include first round leader Miguel Angel Jimenez, JB Holmes, and Vijay Singh - who is using his third different putting grip this season.
