While Martin Kaymer was going one way atop the leaderboard, Kiwi Steven Alker was going the other way near the bottom.
Alker, the only New Zealander in the US Open field at Pinehurst No 2 in North Carolina, shot a second straight six-over 76 to be 12-over for the tournament, with no chance to make the weekend cut in a tie for 148th.
Only seven other golfers in the 156-strong field have completed their second rounds at +12 or worse.
Starting on the back nine, Alker parred his first four holes before a double-bogey at the par-four 14th and a bogey at the par-three 17th wiped away any chance of advancing to the weekend.
Further bogeys at the first and fourth holes, both par fours, came before Alker's lone birdie of the tournament at the par-five fifth. He closed out his round with another double-bogey at the par-four eighth.
Alker failed to fire during the opening round, carding a six-over par 76 in tough conditions.
Alker turned in three-over par after bogeys at the first, third and sixth holes, then dropped three further shots coming home after consecutive bogeys from holes No 15 to 17.
The birdie-free round left him languishing in a share of 122nd place.
The 42-year-old from Hamilton, who won on the US second-tier tour on Monday, less than a week after qualifying for the US Open, also qualified for the Open last year, at Merion Golf Club, finishing 45th.
