Washington Nationals’ lineup + Dusty Baker on Chris Heisey’s injury...

Chris Heisey, who signed a 1-year/$1.4M deal with the Washington Nationals this past winter, was 0 for 14 with a walk and six Ks as a pinch hitter and 6 for 47 overall on the season (.128/.180/.213) before he suffered a right biceps injury in batting practice on Wednesday afternoon.

He told reporters, including MASN’s Byron Kerr, he felt something in his right biceps Tuesday night.

“I came in today, got some treatment and tried to give it a go,” Heisey explained.

“I thought it would be fine. I took a swing in batting practice and actually tore my bicep tendon. We’re going to get an MRI tomorrow.”

“He took a swing in batting practice and he had a bicep rupture and so we’re not sure exactly how long he’ll be out or what procedure or course he’s going to take,” Dusty Baker told reporters after the Nats’ 5-1 win over the Mariners.

“It’s been bothering him on and off,” Baker said.

“I see him shaking it during the course of the game, and so that’s something that was bothering him. He took a swing last night, and usually these things don’t just happen, it’s through the course of time and it’s sad that it happened to such a good guy and a guy that’s one of the spiritual leaders on our team.

“And so we just rally around him the way we did [Adam] Eaton and other guys just have to step up.”

Brian Goodwin was called up after the injury to Heisey, a day after the 26-year-old was sent down to Triple-A to make room on the roster for Joe Ross’s return to the rotation.

How long the Nationals will be without Heisey is unclear. Goodwin gets another shot to get some major league at bats.

Will he take advantage of the chance the way Michael A. Taylor has since he took over in center for Eaton?
