The Netherlands got reinforcements for its bid to win the 2013 World Baseball Classic, adding No. 1 prospect Jurickson Profar and Dodgers closer Kenley Jansen to its roster for the semifinals.

Both Jansen and Profar were on the Netherlands' provisional roster in January. They replace pitcher Jonatan Isenia, out with an elbow injury, and Yurendell DeCaster (leg).  Both players are significant upgrades, with Profar providing power and athleticism in the middle of the diamond. He'll play second base, teaming with shortstop Andrelton Simmons, shifting Jonathan Schoop to third base and giving the team an incredibly athletic infield.

Jansen, who played catcher for the Dutch in 2009 before converting to the mound, gives the team a power arm at the back of the bullpen to complement 7-foot-1 Loek Van Mil.
