JUPITER, Fla. -- The Nationals received left-hander Ian Krol from the A's on Wednesday, completing the Michael Morse trade from Jan. 16.
Krol, 21, was the player to be named later in the deal that sent Morse to Seattle, A.J. Cole and Blake Treinen from Oakland to Washington and John Jaso from Seattle to Oakland.
Drafted in the seventh round of the 2009 MLB First-Year Player Draft out of Neuqua Valley High School in Naperville, Ill., Krol spent last season between High-A Stockton and Double-A Midland in the A's system. He combined to go 2-9 in 29 appearances (15 starts) with a 5.20 ERA.
He was Oakland's Minor League Pitcher of the Year in 2010, going 10-4 with a 2.80 ERA that season in 28 games (27 starts) with Class A Kane County and Stockton.
