Game 76 lineups: Nats at Padres

SAN DIEGO – The Nationals’ lineup is in a bad place right now. That group has averaged 3.3 runs, 8.6 hits and a measly 1.2 walks over the last 18 games, only three of which the team has won. So what’s the cure for an anemic offense? Maybe a rookie knuckleballer making his major league debut?

That’s the unusual situation the Nats find themselves in tonight, with the Padres giving the ball to right-hander Matt Waldron and hoping for the best. The 26-year-old (who throws a knuckleball about 50 percent of the time) was just 1-6 with a 7.02 ERA and 1.650 WHIP in 14 games at hitter-friendly Triple-A El Paso, but with Michael Wacha dealing with shoulder trouble, San Diego is giving him a chance to see what he can do in the big leagues for the first time. This feels like a game that is either going to go wonderfully or horribly for the Nationals, nothing in between.

Josiah Gray’s task tonight is keep the Padres lineup in the yard, something Patrick Corbin and the bullpen couldn’t do Friday. After showing significant progress in this department in April and May, Gray has fallen back into his old pattern from last season, serving up six homers in his last four starts, including two in five innings Monday against the Cardinals.

Speaking of the Nationals bullpen, there has been a roster change. Chad Kuhl was designated for assignment following another rough performance Friday night, and Paolo Espino has been recalled from Triple-A Rochester to take over as a long man in a bullpen that needs more reliable arms.
