Washington Nationals call up Jefry Rodriguez; add Kelvin Herrera; option Wander Suero; Matt Adams to 10-Day DL...

Washington announced this afternoon that both Kelvin Herrera and Jefry Rodriguez were in D.C. for tonight’s second round of the Battle of the Beltways.

In order to make room on the roster for the addition of the two pitchers, the Nationals sent Wander Suero down to Triple-A Syracuse and placed injured first baseman Matt Adams on the 10-Day Disabled list, retroactive to June 16th with a fractured left index finger, the result of a botched bunt attempt on the last road trip.

Nationals’ skipper Davey Martinez announced last night that that it would be Rodriguez who came up to start against the Baltimore Orioles in tonight’s series opener.

Rodriguez, 24, made his MLB debut with 4 ²⁄₃ scoreless in Atlanta in the last series with the Braves, and he gets another opportunity against the O’s, as a starter this time, after he was called upon to take over for an injured Jeremy Hellickson one out into the June 3rd game.

In 13 starts and 68 IP at Double-A Harrisburg this season, he has a 3.31 ERA, a 3.63 FIP, 28 walks (3.71 BB/9), and 72 Ks (9.53 K/9), and a .222 batting average against.

Suero, 26, was the pitcher of record when Juan Soto homered to put the Nationals ahead in the completion of the suspended game against the New York Yankees last night. He earned the win in that game, and walked a batter who came around to score in last night’s 4-2 loss in the nightcap with the Yanks.

In 15 appearances and 17 ¹⁄₃ innings pitched this season, the reliever has a 3.63 ERA, a 4.13 FIP, six walks (3.12 BB/9), 16 Ks (8.31 K/9), and a .212 BAA.

Herrera, 28, put up a 1.05 ERA, a 2.62 FIP, two walks (0.70 BB/9), 22 Ks (7.71 K/9), and a .204 BAA in 25 2⁄3 innings pitched, earning 14 saves for Kansas City before he was acquired last night in a deal that sent three prospects to the Royals.
