PALM HARBOR, Fla. (AP) -- Jordan Spieth should have a good idea what it will take to make the cut in the Valspar Championship.
The last time the world's No. 1 player competed against a full field, Spieth opened with a 79 on Thursday afternoon at Riviera for his worst start ever on the PGA Tour. He returned the next morning and could only try to shoot the lowest score he could and hope that it would be enough.
