MASN’s Dan Kolko reports that lefty Ross Detwiler, dealing with an ailing back, will be placed on the 15-day disabled list. Dan Haren, recovering from inflammation in his right shoulder, will be activated from the DL and start on Monday, taking Detwiler’s spot on the 25-man roster.
Detwiler had compiled a 4.04 ERA over 13 starts. He had previously missed time between mid-May and mid-June with a strained oblique. Haren, on the other hand, has had no success to speak of this season, sporting a 6.15 over 15 starts. Among starters with at least 80 innings pitched, Haren has by far the highest home run rate per nine innings at 2.09, besting second-place Jeremy Guthrie’s 1.68.
The Nationals made a handful of roster decisions on Tuesday, Chelsea Janes of the Washington Post reports. Pitcher Wander Suero was optioned to Triple-A Syracuse and 1B/OF Matt Adams was placed on the 10-day disabled list with a fractured left index finger. With the two open roster spots, the Nationals recalled pitcher Jefry Rodriguez from Syracuse to start against the Orioles and added recently-acquired reliever Kelvin Herrera to the roster.
Adams, 29, was hit on the hand attempting to lay down a bunt on Friday. He has been quite productive for the Nationals this year, batting .275/.351/.575 with 13 home runs and 36 RBI in 171 plate appearances.
Adams was splitting time at first base with Mark Reynolds. Daniel Murphy drew starts at first base over the weekend, so it could be a Reynolds/Murphy split there now with Wilmer Difo remaining at second base.
In his major league debut on June 3, the 24-year-old Rodriguez pitched 4 2/3 scoreless innings in relief of Jeremy Hellickson, who lasted just one-third of an inning. Tuesday’s start will be his first at the big league level. At Double-A Harrisburg this season, Rodriguez posted a 3.31 ERA with a 72/28 K/BB ratio in 68 innings.
