THE COLONY — Just a few short weeks ago, San Antonio’s Christi Cano wasn’t sure how her game matched up to the LPGA professionals she left behind a few years ago.After struggling to a 78 and missing qualification for the North Texas Shootout at Las Colinas Country Club, she wondered how well her latest comeback might be going.On Thursday, Cano took a more modest leap forward and got a jolt of confidence with a four-shot victory in the Texas Women’s Open at Old American Golf Club.It’s Cano’s first victory since the Alamo City merchandiser turned professional in 2003. She earned $2,500 for the win.“I think the biggest thing is that I sign up to play now and it’s not a matter of life and death,” Cano said. “If I play well, great. If I don’t, I’ve got a job waiting on me at home that I really like.”Cano sandwiched two birdies around a bogey on the final three holes to seal the deal over upstart amateur Haley Mills of Tyler.Cruising through the back nine while neck-and-neck with Mills, Cano had a moment of relaxation when Mills was forced to take an unplayable lie after her tee shot on No. 15.But Cano missed her 8-foot par-saver, and Mills made her 7-footer for bogey to stay two shots behind Cano.Both players blistered drives to just a couple of yards short of the green at the 270-yard, par-4 16th.Cano and Mills each converted the up-and-downs for birdie to maintain the two-shot differential.“That was kind of nice to actually have a tee shot that I could potentially reach the green on,” Cano said. “Everything was going so far all day, and the most difficult thing was trying to trust hitting two or three less clubs than I normally would.”Mills made an uncharacteristic double bogey on the par-3 17th, and Cano dropped in a 6-foot birdie at last on No. 18 to polish things off.“I definitely thought I still had a chance and I was battling,” Mills said. “My short game let me down big-time today. I just hit that chip on 17 too hard because I really thought I needed to make par there.”Mansfield’s Rachel Smith was the highest local finisher, shooting 77–153 to finish 14th.Despite a one-shot lead in the senior division, Mina Hardin withdrew before her tee time Thursday, and Anna Schultz of Rockwall held on for a six-shot win.
