Padraig Harrington had to drop to his knees for a recovery shot during the opening round of the 2024 Texas Children's Houston Open.Harrington carded an even-par 70 on Thursday at Memorial Park, finishing with four birdies and four bogeys for the day. On the par-5, 16th hole, his tee shot veered left, landing just below a pine tree. The ball's positioning hardly left him with many options.However, Harrington successfully managed to drag the ball and send it 120 yards away. From there, he encountered little difficulty in securing a par.The 52-year-old Irishman entered Memorial Park after winning the PGA Tour Champions Hoag Classic last Sunday. Currently, he is tied for 54, six strokes behind the leaders, Wilson Furr and Taylor Moore. Both fired a 6-under 64 to take a joint one-stroke lead ahead of the second round.When will Padraig Harrington tee off at the Texas Children's Houston Open 2024?Padraig Harrington is grouped with Sahith Theegala, and Jason Day for the second round of the Texas Children's Houston Open.
