AUSTRIA, 14 Jun 2015 (AFP) - Wood started the final round five shots off the lead which had been held by France's Gregory Bourdy since Thursday.
But a final round of a five-under 67 gave him his first title since the 2013 Qatar Masters.
Woods said he was delighted with victory especially after an injury-hit start to the season when his wrist was in a cast as a result of an injury suffered while playing tennis.
"It was a long winter sitting at home with a cast on my wrist getting frustrated and just wanting to be out here playing and competing," said the 27-year-old.
"I have been playing well the last few weeks so I felt that a victory was coming, but until the moment comes you always think when will it come?
"I played great all week and today especially. I felt that if I could beat 68 today I would have an outside chance and obviously things went my way and 67 was good enough."
Wood finished on 15 under with Spain's Rafa Cabrera-Bello two shots back after a level-par 72 while Bourdy was tied for sixth after a disastrous final round of 78 left him six behind Wood.
Bourdy had led by two overnight but imploded with a double bogey and five bogeys.
