Bratislava, Dec 16 (IANS): Five game victories over the event's top two seeds led to Mahesh Mangaonkar becoming the first Indian winner of the PSA IMET Open, the PSA World Tour Challenger 5 squash event marking its sixth year at the Imet Squash Centrum in the Slovakia capital here.

The 19-year-old World No.98 from Mumbai made his breakthrough in the semi-finals where he downed two-time champion Jan Koukal, the top seed from the Czech Republic expected to make his fourth final appearance in six years, 13-11, 11-8, 9-11, 7-11, 13-11 in 98 minutes.

Third seed Mangaonkar Saturday lined up against defending champion Greg Lobban, the No.2 seed from Scotland who was celebrating his third successive appearance in a Tour final.

Despite his heroics less than 24 hours earlier, the Indian teenager was still able to call upon reserves to recover from losing the first game to take a 2-1 lead.

Edinburgh-based Lobban, ranked 82 in the world, dug deep to take the fourth to force a fifth game decider.

But Mangaonkar refused to give up, reclaiming the advantage to close out the match 7-11, 11-8, 11-4, 6-11, 11-7 after 77 minutes to take the title.

"The turning point of this final was in the second set where I started to move properly on the court," said the jubilant champion after the second Tour title triumph of his career.

"I was happy to win the third, rested a bit in fourth and fought back in fifth. Squash is also a mental game and I gave it all I had in the final set."
