Game 78 lineups: Nats at Padres

SAN DIEGO – Hello from beautiful, sunny Southern California! The Nationals are set to begin a three-game series here against the Padres after winning two of three in Colorado against the Rockies. And they have escaped the extreme heat of both Denver and Washington, D.C. to San Diego, where it is forecasted to be in the mid-70s all week.

Don’t look now, but this series actually has some playoff implications. Yes, it is still June, but entering today, the Nats are only a half-game behind the Padres for the final National League Wild Card spot. With a series victory, they could leave town firmly in a postseason position and at or above .500.

The Nationals are sending Patrick Corbin back to the mound for his 16th start of the year. Although he has only been charged with one run in each of his last two outings, it should be noted that Josiah Gray will be making his fourth rehab start with Triple-A Rochester in the coming days. As he gets closer to his return, the Nats get closer to having to make a decision on their veteran left-hander, who needs another solid outing to make a case for keeping his rotation spot.

Matt Waldron makes his 16th start of the year for the Padres. The right-handed rookie is 5-6 with a 3.46 ERA and 1.164 WHIP this season. He’s currently on a dominant stretch of five straight quality starts in which he’s gone 3-1 with a 1.35 ERA. Waldron hasn’t given up more than two runs in a start since May 5 against the Diamondbacks.

Harold Ramírez is reportedly meeting the Nationals here in San Diego. No roster move has been announced yet, so we’ll see if he makes it in time for today’s game. The Nats signed the veteran outfielder to a minor league contract after he was designated for assignment by the Rays and cleared waivers earlier this month.
