The opening groupings for the 2016 Open Championship have been confirmed as Colin Montgomerie will hit the first shot at Royal Troon on Thursday morning. There are some intriguing match-ups for the opening two rounds of action and we've got a tempting 7/1 treble for Thursday's Threeballs...

2016 Open Championship Threeballs Odds Won/Lost Bet
Paul Casey to beat Schwartzel and Na
@ 8 / 5  
Chris Wood to beat Miyazoto and O'Meara
@ 8 / 13  
Sergio Garcia to beat Lahiri and Bradley
@ 10 / 11  
Treble Returns: @ 7 / 1  

12.53pm - Paul Casey - Charl Schwartzel - Kevin Na
Match Odds:

Paul Casey has gone under the radar again for The Open but he has been admirably consistent this year as his tie for 16th at the WGC Bridgestone Invitational was his fifth top-25 finish of the year and he will be relishing a return to Troon, where he finished in the top-20 in 2004. The Englishman's pragmatic style ensures he is a decent bet to come out on top in his threeball grouping with the mercurial Kevin Na and Charl Schwartzel.

The South African Schwartzel has won twice this year but he has missed two of the last three cuts when visiting Scotland and it seems odd that he would change his club manufacturer prior to the third major of the year.
Tip #1: Paul Casey to beat Charl Schwartzel and Kevin Na @ 8/5 with Coral.

2.26pm - Chris Wood - Yusaku Miyazato - Mark O'Meara
Match Odds:

Chris Wood is another Englishman who could be something of a dark horse this summer as he is a fine links exponent who tends to enjoy visiting Scotland as his last four appearances at the Alfred Dunhill Links Championship have all yielded top-fifteen finishes. Wood, who was the leading amateur at the 2008 Open and tied 3rd at the 2009 edition, is in red hot form right now as he followed up his win at the BMW PGA Championship with three successive top-25 finishes and he can get the better of his rivals on Thursday.

Yusaku Miyazato did tie for 23rd at the US Open but he missed the cut on his only previous Open appearance in 2014, while 1988 Open winner Mark O'Meara is well past his best.
Tip #2: Chris Wood to beat Yusaku Miyazato and Mark O'Meara @ 8/13 with Coral.co.uk.

2.48pm - Sergio Garcia - Anirban Lahiri - Keegan Bradley
Match Odds:

Sergio Garcia's close affinity with the Open, where he has finished in the top-ten on nine occasions during his career, ensures he is the value for his threeball grouping with Anirban Lahiri and Keegan Bradley. The Spaniard has been a fast starter as he boasts an impressive first round scoring average of 69.30 on the PGA Tour this season and he is in great touch, with the Byron Nelson winner finishing in the top-five in his last two outings at the US Open and WGC Bridgestone Invitational.

He comes up against Lahiri and Bradley, who has been in woeful form with ten missed cuts and just one top-ten finish to show from seventeen starts worldwide this year.
Tip #3: Sergio Garcia to beat Anirban Lahiri and Keegan Bradley @ 10/11 with Coral bookmakers.
