Gio Gonzalez and Jayson Werth appeared to be arguing in the Nationals’ dugout after the first inning of Tuesday’s game against the San Francisco Giants. Gonzalez didn’t cover first base on a potential double play ball hit by Buster Posey, instead forcing the Nats to settle for one out when Adam LaRoche threw to Ian Desmond at second base for the force. It’s unclear if that is what bothered the two players. Gonzalez also might have been unhappy with Werth’s effort chasing down a double by Joaquin Arias earlier in the frame.

After Gonzalez escaped the inning unscathed, the two players talked as they walked off the field and into the dugout. Television cameras then caught Werth and Gonzalez in an apparent disagreement. Werth walked by Gonzalez in the dugout and the two exchanged words. As Werth walked away, Gonzalez continued talking and shouting. With other players watching, pitching coach Steve McCatty held Gonzalez back and hitting Rick Schu stood in between them.

Something seemed awry with Gonzalez, too, which might explain why he didn’t get to first base in time on Posey’s grounder. Television cameras caught Gonzalez stretching his back while talking to McCatty and head trainer Lee Kuntz in the second inning, and the pitcher seemed to grab his back after one play in the third inning.
