Tyco Suzuki's Guy Martin secured a quick-fire double at the Armoy Road Races as the Lincolnshire star mastered the wet conditions in the Superbike and Supersport classes.
Martin, who was forced to settle for the runner-up spot behind team-mate William Dunlop in Friday's opening Supersport race, made amends as he cinched his first ever victory at Armoy in the second 600cc encounter.
The 32-year-old was locked in battle with Scotsman Keith Amor in the rain, although the Rig Deluge Honda rider blew his chance when he ran on at the hairpin on the last lap.
Martin went on to seal the win by 6.6 seconds over William Dunlop, with Amor recovering to clinch third place. Derek McGee finished fourth ahead of Michael Dunlop, with Derek Sheils rounding out the top six.
Martin was a start-to-finish winner in the opening Superbike race on the Tyco Suzuki GSX-R1000, which was also run in heavy downpours.
The reigning Southern 100 Solo Champion shot into the lead and stayed there until the finish, holding on to win by 0.819 seconds from pole man Michael Dunlop.
Martin had a lead of 2.78 seconds over William Dunlop at the end of the third lap of the five-lap race, which was cut in distance due to the conditions at the three-mile circuit.
However, once 11-times TT winner Dunlop found a way past his older brother he began to eat into Martin's advantage, but it was too little too late as Martin held on to complete a double.
William Dunlop finished third, eight seconds further behind, with Manxman Dan Kneen, Keith Amor and Derek McGee completing the top six.
Martin has been in terrific form of late and will be relishing next month's Metzeler Ulster Grand Prix, where the Suzuki star bagged a treble in 2013, including wins in both Superbike races for Northern Ireland team Tyco Suzuki.
