TODAY: The Nationals have officially announced the signing, adding Parra on a one-year contract.

YESTERDAY: The Nationals are moving fast on newly minted free agent outfielder Gerardo Parra. After hitting the open market just yesterday, he’s now reportedly due to join the Nats on their current road trip.

Parra, 32, had been designated for assignment by the Giants as they cleared the deck for younger options. He is slashing just .198/.278/.267 through 97 plate appearances on the season.

For the Nats, the veteran left-handed hitter may help plug one of the team’s many leaks. Andrew Stevenson suffered a back injury after being called up to bolster the outfield unit while Juan Soto works back to health. With lefty slugger Matt Adams also sidelined, the club is short of southpaw swingers.

Parra is known more for his glovework in the outfield than his bat, though he has at times been an above-average hitter. Through nearly five thousand MLB plate appearances over eleven seasons, he owns an 88 wRC+ — though he’s closer to league-average (96 wRC+) when hitting with the platoon advantage, as he likely will for the most part in D.C.

It is not yet known how the Nationals will clear the necessary roster space for this move. Placing Stevenson on the injured list could open an active roster spot, but that wouldn’t account for the 40-man.

Kerry Crowley of the Mercury News first made the connection on Twitter. ESPN’s Jose Rivera first tweeted that a deal was agreed to. Also reporting the match were Sam Fortier of the Washington Post (Twitter link) and Jon Heyman of MLB Network (via Twitter).
