Swedish golf star Ludvig Åberg had a shaky first round in the Masters rehearsal in San Antonio, Texas.
With six birdies and five bogeys, the 25-year-old landed far down in the results list, in a tie for 43rd place, with one stroke under par.
Jesper Svensson played steadily and landed two strokes under par after three birdies and one bogey, which gives a tie for 19th place. American Sam Ryder leads the competition with nine strokes under par.
This year's first major, the US Masters at Augusta National, will be played on April 10-13. Last year, Åberg came second in the competition, which was also his major debut.
