Tiger Woods the Golf star Tiger struggled through most of the 139th Open Championship, majorly due to a switch to a new putter designed by Nike.

Woods said that he used the Nike Method putter in anticipation that it would help him adjust to the slower speed of the greens in the Old Course at St. Andrews, Scotland. Woods had hit the ball well off the tee , but he struggled putting. And finally he ended up scoring a frustrating 1-over-par 73 Saturday to fall well behind leader Louis Oosthuizen, who has finished at 15-under-par.

“I hit it good today,” Woods told reporters. “I mean, I striped it all day. I just didn’t get anything out of the round. I couldn’t build any momentum and wasn’t making any putts.”

Woods was in the final round on Sunday in an attempt for pulling off something that he had never done i.e. claiming a major championship win after coming from behind in the last round. In all the 14 victories, Woods held the lead going to the final round.

He told reporters that he switched back to the to the Scotty Cameron putter made by Titleist. He has used the Titleist putter since 1999.

“I don’t know what’s going to happen,” he said before teeing off. “The forecast is for it to be windy and possibly a few showers here and there, but you don’t know. We’ll see what happens.”
