Amid the bottom of the 10th inning of a tie game at Camden Yards, Anthony Santander told Austin Hays not to worry about getting ready to hit. The inning, Santander said, would not get past Ryan McKenna. He proved prophetic when McKenna, in his first at-bat Saturday afternoon after replacing Santander in right field an inning earlier, launched a walk-off, two-run home run to give the Orioles a 6-4 victory over the Seattle Mariners. “I called it,” Santander said proudly.
