(CNN) -- A stunning 10-under par round of 62 fired Bubba Watson to the top of the leaderboard at the halfway mark of the WGC-Cadillac Championships on Friday. The left-hander followed up his opening round of 70 with a string of birdies -- nine in all -- and an eagle with the only bogey coming six holes from home. The American leads by one from his playing partner Justin Rose who had a similarly happy time of it on the TPC Blue Monster course in Florida. The Englishman finished with flawless eight-under par round of 64. Joint first-round leader Adam Scott finished the day strongly (four birdies on the closing six holes) to claim third place on 10-under.
