ROGERS, Ark. (AP) -- Whether it's because of her improved play or the reason for it, Michelle Wie appears as comfortable on and off the golf course as at any time in her career.
Wie continued her season-long surge on the LPGA Tour on Saturday, shooting her second straight 5-under 66 to take a two-shot lead in the suspended second round of the NW Arkansas Championship.
The performance put the U.S. Women's Open champion within a round of back-to-back wins for the first time in her LPGA Tour career, not that she showed any signs of stress after reaching 10 under overall.
In fact, shortly after surging into the lead at Pinnacle Country Club, Wie joined PGA Tour pros Rickie Fowler and Keegan Bradley as part of a social media challenge in dumping a bucket of ice water on herself on the driving range.
Yes, life is good at the moment for Wie.
"I think it comes hand in hand," Wie said about her winning and revamped attitude. "... I played really well toward the end of the year last year ... took a lot of time off, took about a month and a half. So, I just felt really refreshed, and I think it comes hand in hand."
All 72 players in the afternoon session were unable to finish on Saturday because of thunderstorms, with second-round play expected to finish early Sunday before the final round begins later in the morning.
Before the rain arrived, the morning pairings were once again left chasing Wie -- who earned her first major victory at the U.S. Women's Open last week at Pinehurst after winning earlier in the season in her home state of Hawaii.
So Yeon Ryu, paired with Wie, was second at 8 under after her second straight 67, while Suzann Pettersen, Chella Choi and Line Vedel were three strokes back. Pettersen had a 67, Choi shot 65, and Vedel had five holes left.
Top-ranked and local favorite Stacy Lewis was four shots behind at 6 under, a week after finishing a shot behind Wie at Pinehurst. The two are training and practice partners in Florida, and Wie couldn't help but challenge her friend to the ice bucket shower after her dousing.
"Michelle's obviously playing some really good golf," Lewis said. "I'm going to have to shoot a good number tomorrow.
