McGuinness can't split Dundalk duo Trainer Ado McGuinness is doubly represented in the BAR 1 Betting 'Best Odds Guaranteed Overnight' Handicap at Dundalk on Friday evening.  While bookmakers make Serenity Blue a general 4/1 market leader, McGuinness admits that there is very little separating the recent UK import and his more established stablemate Star Harbour (9/1).  The former won over a-mile-and-a-half on his Irish debut at the same track last month, before finishing fourth on his most recent appearance. Meanwhile, Star Harbour is on somewhat of a recovery mission having disappointed at Listowel last time.  McGuinness said: "Both of them have good chances, hard to pick them at home. "Adam (Caffrey) has gone for Serenity Blue, but Star Harbour loves this place. He had a little bit of a mishap after Listowel, but he is in good form. "They are in good order."
