Tagger, who is the youngest player inside the world's top 100, will move to a career-high ranking of 45th in the world tomorrow, after overcoming an opening-set scare to triumph in one hour and 30 minutes.
The aggressive Austrian possesses a glorious single-handed backhand - one of just four in the top 100 - and hit nine aces as she denied Snigur her first WTA triumph.
Tagger trailed 2-5 in the first set, but managed to find her feet to retrieve the break before winning the opener on a tiebreak.
From then on, it was more straightforward for her, cruising to the finishing line to get her hands on the trophy in the Czech capital.
