Rory Mcilroy is up against Lee Westwood in the very important semi finals of WGC Match play which will be held in Arizona. If either of the two players end up winning the tournament then Luke Donald of England will have to give up his number one position to him. Lee Westwood had to beat Martin Laird in the quarter finals to make it against Rory Mcilroy. It was not an easy match for him as he lost the first hole against the Scotsman but ended up winning the match four and two. Rory Mcilroy on the other hand had to get past Sang-Moon Bae to make it to the semi finals.
