Worth noting

• Nationals left-hander Ross Detwiler will start against the Yankees on Monday. He will be followed by Tanner Roark and Chris Young. Stephen Strasburg will start against the Braves on Tuesday.

• Jayson Werth will play his first game against the Marlins on Sunday.

• Major League Baseball Players Association executive director Tony Clark and special assistant Dave Winfield led a contingent that visited Viera, Fla., on Saturday to talk with the Nats in an annual Spring Training meeting. According to Nats player representative Drew Storen, the new MLB rules regarding instant replay and home-plate collisions were discussed, and the meeting also gave young players unfamiliar with the union a chance to learn more about what it does.

This is the first year as executive director for Clark, who took over the job after Michael Weiner passed away in November, following a battle with brain cancer. Clark, who played 15 years in the big leagues, has worked with the MLBPA since 2010 and had been deputy executive director since July.

"Tony worked under Michael and learned from Michael," Storen said. "Michael was a great person and great leader for us, and it was an unfortunate situation, but having Tony Clark step in, he knows the game from both sides. He's an incredible leader and he has a real presence when he talks to the room."
