The Nationals announced that they acquired left-hander Ian Krol from the Athletics (Twitter link). The move completes the three-way trade that sent Michael Morse to Seattle in January. The A's acquired John Jaso in the deal and sent minor league right-handers A.J. Cole, Blake Treinen and a player to be named to Washington.
Krol, 21, spent the 2012 season at Class A and Double-A. He spent most of the season with the Stockton Ports of the Class A California League, posting a 5.21 ERA with 8.2 K/9 and 2.5 BB/9 in 86 1/3 innings. The A's initially selected Krol in the seventh round of the 2009 amateur draft.
