Rome:Number nine seed Guillermo Coria joined Andre Agassi, Rafael Nadal and David Ferrer in the last four of the Rome Masters on Friday, after coming from a set down to beat Spanish giant-killer Fernando Verdasco. Verdasco, conqueror of top seed Andy Roddick in the last 16, took the first set 6-3. He could have created a winning position in the second before Coria rallied to take the next two by the same score and set up a semi final match with Agassi, a player he has beaten only once in their six previous meetings. The last of the four quarter final matches at the Rome Masters took place under lights at the Foro Italico Centre on Friday, with Guillermo Coria up against the surprise package of the tournament, Fernando Verdasco. The 21 year-old Spaniard had beaten the top seed, Andy Roddick in straight sets in the previous round and brought a lot of confidence with him into the quarter finals. Verdasco took the first set 6-3 and looked set to open up another advantage in the second, making his Argentine opponent do all the running. Putting up a fight But Coria hung on, breaking the Spanish serve in the third game and saving a break point in the fourth. Having narrowly failed to defend his only Masters Series crown in Monte Carlo last month, Coria was in no mood to tumble meekly out of this one. The Argentine levelled the match at one set all and a single break was all it took in the decider, although a marathon match point lasted all of 21 strokes before Verdasco's attempted drop shot failed to clear the net. Coria had won 3-6, 6-3, 6-3 in two hours and four minutes - a much closer run thing than their last encounter two years ago in Barcelona, when Coria won at a canter, two and two. Now he faces the number six seed Andre Agassi in the semis, a player he has beaten only once in six attempts. The American may have turned 35 a week ago, but in their last three meetings, including one this year at the Masters Series event at Indian Wells, Coria has failed to take a set.
