WARSAW, May 19 (Xinhua) -- Former world number one Maria Sharapova made a successful comeback to women's singles with a hard fought 6-1, 6-7(6), 6-3 victory over Italian Tathiana Garbin in the first round of the Warsaw Open on Monday.

    Sharapova had not played singles since last August because of a long-time shoulder injury although she made a brief return to competition in

    the doubles at Indian Wells in March, losing in the first round.

    The Russian started strongly, taking opening set at 6-1 and leading 4-0 in the second, but the gritty Italian came back strong to steal the tiebreak at 8-6.

    Garbin was still in control of her game at the start of the decider, breaking again to take a 3-1

    lead. Sharapova finally cooled down to take the match at 6-3.
