One-day international, Glasgow: India 212-3 (39.5 ovs) bt Scotland 203-9 (46 ovs) by 7 wkts (D/L method)
Gambhir was named man-of-the-match after an unbeaten 85
India sealed a comfortable seven-wicket win with 37 balls left in their first one-day international with Scotland.
Chasing a revised 209 from 46 overs they reached 100-0 in 20 overs as Robin Uthappa hit a huge six in a fluent 55.
Gautam Gambhir shared 61 in eight overs with Yuvraj Singh and remained unbeaten on 85, his fourth one-day half century.
Gavin Hamilton and Neil McCallum had rescued the Scots with a stand of 82 and Craig Wright's innovative 37 from 34 balls took them to a useful 203-9.
On a bracing morning in Titwood, Glasgow, Rahul Dravid, draped in three layers of clothing, chose to unleash his bowlers on a green-tinged pitch.
But the seamers often struggled with their line, Ajit Agarkar and RP Singh sending down three wides each in an over - there were 20 in total.
It was Agarkar who made the first breakthrough, pinning Navdeep Poonia on the crease in the fifth over, umpire Ian Gould sending the batsman on his way in windmill fashion.
Fraser Watts made a scratchy six from 28 balls before he edged RP Singh to give keeper Mahendra Dhoni a simple catch off the final ball of the eighth over.
Watson began to increase the scoring before falling at mid-wicket
Majid Haq struck the opening boundary with an elegant square drive in the ninth over, with Watson cutting to the fence in the next during an encouraging spell for the Scots.
There was a moment of controversy with the score on 49-2, Watson trying to hit over the top and mis-timing to mid-off where RP Singh claimed a catch diving forward.
The Scotland captain was convinced the ball had not carried and after some confusion the umpires decided to reinstate him.
His reprieve was not significant as he clipped to square-leg four balls later without adding to his score.
The next ball produced another wicket as Haq top-edged a pull but a rain delay of around 35 minutes, which cut the innings to 49 overs, favoured Scotland more than the tourists.
Spinner Ramesh Powar, resembling a cartoon character with his red sunglasses, was introduced in the 24th over but was despatched gloriously back over his head for six by McCallum.
A moment of fortune saw McCallum's top-edged sweep fall just beyond square-leg, but he used the stroke to good effect with two boundaries in three balls off leg-spinner Piyush Chawla before cutting one that was too close to him.
Scotland's most-capped player Wright struck two boundaries off Agarkar but the seamer claimed his second wicket with a slower one that Hamilton missed as he tried to sweep.
Wright had more punishment for Agarkar, a soaring straight drive disappearing out of the ground before the veteran was run out in the final over.
Hamilton shared an important stand with Neil McCallum
After their late resurgence with the bat, the Scots applied the pressure with the ball, and with the addition of some alert fielding they restricted India to just 15 from the opening seven overs.
Uthappa showed signs of frustration when he charged down the pitch to skew one off a thick edge, and came close to being run out when he took a second run and Smith took a fraction too long to take the bails off, following a fine throw from the boundary by Watts.
But the right-hander soon began to find his touch and was particularly impressive with some powerfully struck straight drives.
Uthappa stormed down the pitch to swat Dewald Nel high into the back row of the mid-wicket stand.
But Wright continued his impressive display when he nipped one back to take Uthappa's inside edge and uproot the off-stump in the 21st over.
Having played an accompanying role to the bold Uthappa, Gambhir completed his fifty from 76 balls and started to play with more freedom.
Haq was rewarded for some tidy slow bowling when Dinesh Karthik was well caught at mid-wicket.
Yuvraj was promoted above Dravid, and despite the anguish of an inside edge into his thigh plus a bottom edge under the keeper's gloves he quickly lofted Wright into the marquee at long-on as 16 came from the seamer's final over.
Gambhir recorded the fifty stand with Yuvraj from 43 balls with a six over long-off against Paul Hoffman, playing his final match for Scotland.
There was no closing success for the veteran seamer, Jon Blain claiming the final wicket to fall when Yuvraj was yorked for an entertaining 38.
That brought Dravid to the crease against the team he played for in 2003 and the captain nonchalantly flicked Nel off his pads for four to get off the mark, and a similar stroke secured the winning runs.
