The Chicago Cubs today added right-handed pitcher Henry Rodriguez to the active roster after he was acquired on Tuesday from Washington for minor league right-handed pitcher Ian Dickson. In a corresponding roster move, left-handed pitcher Brooks Raley has been optioned to Triple-A Iowa.

Rodriguez, 26, will wear uniform number 62 and is available for tonight's game at Citi Field against the Mets.

Rodriguez went 0-1 with a 4.00 ERA (8 ER/18.0 IP) in 17 relief appearances with the Nationals this season. The righthander limited opponents to a .203 batting average against (14-for-69), including a .194 mark by righthanders and a .211 mark by lefthanders. Rodriguez was designated for assignment on June 4.

The native of Venezuela has pitched in parts of five major league seasons with the Oakland Athletics (2009-10) and the Nationals (2011-13), going 5-7 with 11 saves and a 4.23 ERA (68 ER/144.2 IP) in 143 relief appearances. He has struck out 149 batters in 144.2 innings pitched. In his first season with the Nationals in 2011, Rodriguez went 3-3 with two saves and a 3.56 ERA (26 ER/65.2 IP) in 59 relief appearances, setting career bests in wins, ERA and outings. He set a career high with nine saves with the Nationals last season.

Raley, 24, was recalled by the Cubs on Wednesday, but did not appear in a game. He is 5-4 with a 4.92 ERA
(35 ER/64.0 IP) in 13 appearances (12 starts) with Iowa this season.
