Brandon Williamson gave up a run in the first, another in the second and two more in the third Tuesday night, and everything could have easily come undone for the 25-year-old left-hander and the rest of the Cincinnati Reds. Instead, Williamson cruised through two more innings without a hit, turned over a 5-4 lead to the stingy Cincinnati bullpen, and watched a quartet of relievers allow a single hit the rest of the way in beating the Kansas City Royals. “They really thrive on that,” said Reds manager David Bell, whose club faced an early 1-0 deficit against the Royals and has now won a National League-leading 22 games in come-from-behind fashion.
