The Bristol pro, who was sidelined for five months after breaking a bone in his wrist last October, took advantage of a final-day collapse from long-time leader Gregory Bourdy to clinch a two-shot win in testing conditions at the Diamond Country Club in Atzenbrugg.
Wood made five birdies and kept a bogey off his card in a composed five-under 67 for a winning score of 15 under, two clear of Rafa Cabrera-Bello and five ahead of fellow Englishmen Robert Rock, Robert Dinwiddie and Matthew Fitzpatrick.
Bourdy started the final day with a two-stroke advantage, and he looked in confident form as he birdied the first only to make a mess of the par-three second hole and run up a double-bogey five.
As the Frenchman faded, Wood applied the pressure when he followed birdies at two of the first three holes with another at the sixth, and he soon found himself as the outright leader when Cabrera-Bello bogeyed three straight around the turn and Bourdy blotted his card again at the 11th.
Bourdy dropped out of contention with further bogeys at 13 and 14, but Cabrera-Bello kept himself within two shots of Wood as he matched the Englishman’s birdies at the par-five 15th and 16th.
But Wood held his nerve to close with a pair of solid pars, and the Spaniard was unable to find a birdie over the last two holes and had to settle for a level-par 72 and outright second place – his best finish of the season.
Rock secured his third top-10 of the year as he birdied three of the last four holes to cap a 66 and briefly claim the clubhouse lead on 10 under, a score later matched by Dinwiddie as he returned a flawless four-birdie 68.
Fitzpatrick made it an all-English share of third place after a mixed-bag of a 71, while Bourdy limped in with a disappointing 78 to finish in a tie for sixth on nine under along with Kristoffer Broberg and John Hahn.
