SSP Chowrasia opened with a one-under 71 while Jeev Milkha Singh carded one-over 73 in the first round of the Johnnie Walker Championship at Gleneagles here.
Chowrasia, winner of two European Tour titles, had three birdies and two bogeys. Jeev's 72 included four birdies and an equal number of bogeys.
Austrian Bernd Wiesberger and Argentine Ricardo Gonzalez took advantage of perfect scoring conditions to share the lead after the opening round.
Both players carded seven under par rounds of 65 over the Centenary Course, which will stage next year's Ryder Cup. They lead by one from in-form Australian Brett Rumford, Spin's Ignacio Garrido, Thailand's Thongchai Jaidee and English trio Oliver Fisher, Ross Fisher and Mark Foster.
Wiesberger, twice a winner on The European Tour last season, came into the event in good form having made 17 consecutive cuts this season and continued to shine with three straight birdies to finish.
Italian Ryder Cup star Francesco Molinari opened with a three under 69, while defending champion Paul Lawrie birdied two of the last three holes to be a shot further back.
