Maguire won four frames in a row to seal the win after his opponent had battled back from 2-0 down to level the scores.

But the Scot, who edged past Ronnie O'Sullivan in the last eight on a respotted black in the final frame, had six breaks over 50 as he set up a meeting against former world champion Peter Ebdon.

Maguire won this tournament in 2008 and started strongly here, taking the first frame with a 76 break and then edging a scrappy second as he punished Lee for not taking his chances.

Lee beat reigning champion Judd Trump in the last eight and the 37-year-old battled back to level after four frames.

He won the third frame on the back of a 67 and then drew level, breaks of 47 and 39 enough to get over the line.

But he simply had no answer to Maguire after the mid-session interval as the 31-year-old raced away with the match.

The Scot knocked in a 51 and a 53 to restore his lead and improved from there.

He rattled in breaks of 66 and 71 to take the match away from Lee before saving the best till last, a run of 91 handing him victory in emphatic fashion.

Ebdon comeback

Qualifier Ebdon came from 3-1 down to beat home favourite Ding Junhui 6-3 in the second semi-final.

Ding looked set to delight his legion of fans in Beijing when he led by two frames at the mid-session interval, but Ebdon reeled off the next five in succession.

After winning the first frame after the interval, a break of 69 saw Ebdon level the scores at 3-3 before an epic seventh frame which lasted 37 minutes.

With just the last three colours remaining, Ding missed a straightforward blue to the middle while trying to force position on the pink, which was near the yellow pocket.

Ebdon potted the blue and then brilliantly cut the pink in from a narrow angle, while still managing to get position on the black on its spot.

The Londoner then compiled a break of 68 in the next frame which was ultimately enough to win it, before sealing victory with runs of 64 and 58 to win the ninth frame 127-0.
