O'Sullivan sets up Maguire semi



World number one Ronnie O'Sullivan rattled in two centuries to see off Ali Carter 6-2 and set up a Masters semi-final clash with Stephen Maguire. O'Sullivan was not at his fluent best but went into overdrive as Carter crumbled after the mid-session break. The first four frames were shared in an enthralling start but after a re-rack in the fifth O'Sullivan made breaks of 82, 128, 115 and 91 to seal the win. Scotland's Maguire beat Neil Robertson 6-3 in Friday's earlier quarter-final.
