SAN JOSE, Calif. (AP) _ John McEnroe took another successful step in his comeback with a thrilling victory in the doubles semifinals of the SAP Open, while top-seeded Andy Roddick lost to Britain's 18-year-old upstart, Andy Murray, in singles.

McEnroe, 47, and his partner Jonas Bjorkman beat Jaroslav Levinsky and Robert Lindstedt 6-3, 4-6, 10-8, with the third set being decided by a tiebreaker. In the newly shortened doubles scoring format, the first team to 10 points by a margin of two wins, with no regular third set being played.

McEnroe and Bjorkman will face Paul Goldstein and Jim Thomas in Sunday's doubles final. McEnroe is looking for his 78th professional doubles title, to go along with his 77 singles titles.

``There's one more to go and it's two Stanford boys, apparently, so I hope they've got the script right,'' said McEnroe, who also played at Stanford.

``We've come this far so we might as well go all the way,'' he added.

McEnroe's reached an ATP final for the first time since winning an indoor doubles title in Paris on Nov. 8, 1992, with his brother, Patrick.

Murray, ranked No. 62 in the world, hit his groundstrokes deep throughout the match and got key points against Roddick's big serve when he needed them in a 7-5, 7-5 victory.

``I have so much respect for a guy like Roddick. He's achieved so much,'' Murray said after the match. ``It's great just to be on the court with him. To beat him is amazing.''

For Murray, it's on to face third-seeded Lleyton Hewitt in Sunday's final. As for Roddick, it's back to the drawing board.

``It just seemed like I couldn't get the ball to go through the court like I would have liked,'' Roddick said. ``It was difficult. I wasn't getting much bite on my service action. It was frustrating.''

Murray said his service returns were key.

``He obviously didn't serve as well as he can. I don't know if that was because I was returning very well or if he just wasn't feeling as confident as he normally was,'' Murray said.

Murray said he is expecting an intense match with Hewitt.

``He's got a great attitude. He's going to fight for every point,'' Murray said.

In the earlier semifinal, Hewitt used a smart array of angles on his serves and groundstrokes to defeat Vince Spadea 6-3, 6-4.

Hewitt had an answer for everything Spadea dished out, especially
from the backcourt where the Australian's foot speed gave him a huge
advantage on the indoor court.
