"[Gwynn Jr.] is a great guy. Even when I was playing [for San Diego State], he would always come around," Strasburg said. "He would talk to us and the other guys. He is a great personality, just like his dad."
Gwynn has a chance to make the Nationals as a fourth outfielder. With outfielder Jayson Werth limited as he recovers from Jan. 9 surgery on his right shoulder, Gwynn will get his share of playing time.
"He is a lot like Denard [Span] in the work ethic, preparing for every at-bat in the game. He wants to excel on all parts of the game," Strasburg said.
Gwynn tweeted his appreciation for a chance to contribute to the Nationals, writing: "So happy and grateful for the opportunity to continue to play the game I love! #Nationals"
