    The Shell Houston Open at Redstone G.C. in Humble Texas finally got the 1st round completed, with Phil Mickelson joining the leaders at the top of the board. Phil shot a -7 under par round of 65 to equal the scores of Carl Pettersson and Angel Cabrera, who had completed their rounds before the abandonment of play due to inclement weather yesterday. Phil had to restart this morning and finish his first round, before going on to contest the second, a long day ahead. Prime time for scoringHalleran/Getty Images
