Twenty-five players returned to TPC San Antonio on Saturday morning to complete the second round, which was delayed Friday due to a two-hour weather delay.
Round 1 leader Matt Every finished the 17th hole with a birdie to get within two of the lead, but he bogeyed the 18th to finish at 7 under, three back of Ben Curtis, who finished Friday.
The cut remained at 4 over. Rookie Billy Hurley III holed a six-footer for par to make it on the number.
The winds are expected to make it rough on the leaders late Saturday, with wind gusts of around 20 mph.
