When he came up to bat in the eighth inning of a 3-2 game against the Atlanta Braves, Jayson Werth told Nationals Manager Davey Johnson that he would need a pinch runner if he reached base. Werth said he his hamstring was tight all day and he couldn’t get it fully loose before the game. Towards the end of the game, he felt cramping and in particular in the seventh inning raced to catch a flyball and make a throw home to try to cut down a run. During his eighth inning at-bat against left-hander Eric O’Flaherty, Werth fouled a ball off his left ankle. He fell to the ground, rolled around and got up gingerly. Trainer Lee Kuntz and Johnson came out to check on him. He finished the at-bat but was replaced the next inning in right field by Roger Bernadina. “I wanted to hit,” Werth said. “I felt like take our chances there against a lefty. So he let me hit, but I told him with me being the tying run, he’d probably need to run for me.” Werth said his cramping was minor. The foul ball off the ankle aggravated the situation, he said. Two teammates have dealt with hamstring issues over recent weeks, Ryan Zimmerman and Wilson Ramos. Zimmerman’s hamstring strain, which landed him on the 15-day disabled list, began as hamstring cramping. Werth said it was too early to tell if he would need time off to rest his leg. “Have to see how I feel (Tuesday),” he said.
