Paul Konerko perfectly summed up his fortunes after leaving Saturday’s game in the sixth inning because of neck stiffness that probably will sideline him for Sunday’s series finale against the A’s. “It’s all part of the fun,” Konerko said sarcastically after pain hampered his swing and put a dent in his progress. Konerko was batting .400 over his last seven games before striking out twice against A’s starter Dan Straily. “I’ve missed sliders when I’m 100 percent healthy, but I knew what I couldn’t do,” said Konerko, who said the soreness surfaced when he woke up Saturday. “If I had a fastball down the middle, I knew I couldn’t take a good swing at it. From my second at-bat, it was getting worse. “Sometimes it’s not about pain; it’s about restriction, what you can get to. It was going to be tough to keep two hands on the bat.” Before Konerko’s injury, manager Robin Ventura already had planned to start backup outfielder Dewayne Wise and perhaps Casper Wells, who took over the designated hitter duties for Konerko and went 0-for-2.
