LONDON (Reuters) - Grigor Dimitrov stood one win away from the biggest title of his career on Saturday after ending his Jack Sock jinx to reach the final of the season-ending ATP Finals at the 02 Arena.
The Bulgarian, finally beginning to look the real deal after year's weighed down by comparisons to Swiss great Roger Federer, produced more dazzling tennis to win 4-6 6-0 6-3 and set up a Sunday showdown with fellow debutant David Goffin.
