“Nothing yet,” Baker said Saturday. “He had to be driven home after last night so we’re waiting from the MRI becuase it’s not that easy. Not that many people working on Saturdays. Hopefully it’s not as serious as looked.”
Despite the team’s announcement of a knee strain, Baker said Saturday he couldn’t be sure when asked if the injury was to Eaton’s knee or ankle.
“I don’t know. Could be one or both,” he said. “We’ll find out when we get the MRI.”
Eaton hit a roller to the left side of the infield and just barely beat the throw to first. After reaching the bag, he collapsed in a heap as the crowd at Nats Park fell silent.
The 28-year-old outfielder, acquired in a blockbuster December trade with the Chicago White Sox, is hitting .297 with a .393 on-base percentage.
To take his place on the roster, the Nationals recalled outfielder Rafael Bautista from Triple-A Syracuse, where he was hitting .291. His 224 career stolen bases since 2012 ranks fifth in minor league baseball.
