World number six Jordan Spieth looks set to miss the cut at the Houston Open, the final event before his attempt to reclaim the Masters title.
Spieth appeared set to win the green jacket for the second consecutive year at the 2016 Masters, only for a final-day collapse to hand the title to Danny Willett.
He will try to make amends for that meltdown at Augusta next week, but will not head to Georgia in great form having finished two over after the first 36 holes in Texas.
Having carded a three-under 69 in the first round, Spieth endured a woeful second day, posting a five-over 77, his only birdie coming at the 15th.
That put him three shots below the projected cut line, and there looks to be work to do if Spieth is to win a second Masters crown in three years.
