In return, the Marlins will receive second baseman Emilio Bonifacio and two minor leaguers: Single A right-hander P.J. Dean and outfielder Jake Smolinski.
For the Marlins, the moves follow the team’s usual pattern, reducing payroll while adding young talent with strong potential. In this case, the Nationals are the beneficiaries. Both Olsen, 24, and Willingham, 29, are entering their first year of arbitration, and will be under the Nats’ control for the next three seasons.
Olsen, who pitched 201 2/3 innings last season while going 8-11 with a 4.20 ERA, immediately becomes the ace of a Nationals’ staff in desperate need of top-of-the-rotation help. He had also been the subject of trade discussions between the Marlins and Rangers
Willingham likely will take over in left, giving the Nationals additional depth in an outfield that already includes Lastings Milledge, Austin Kearns and Elijah Dukes — and possibly leading to another trade.
Without Olsen, the Marlins’ rotation will include right-handers Josh Johnson, Ricky Nolasco, Chris Volstad and Anibal Sanchez, along with left-hander Andrew Miller. The addition of Bonifacio will enable the team to trade Dan Uggla, move him to third base or keep him at second, where his value as an offensive player is highest. Under the latter scenario, Bonifacio could become a super-utility man, opening up the possibility of trading Alfredo Amezaga, who is coveted by many clubs.
Smolinski, 19, is coming off reconstructive knee surgery. He was the Nationals’ second-round pick in the 2007 draft and Dean was their seventh-round selection out of New Caney (Texas) High School that same year.
