I too would like to keep Rondon around. I think the fact that he doesn't have an option gives him a decent chance of sticking. The Sox talked about getting him some OF playing time in winter ball - seems that was more talk than action. He has primarily played 3B in winter ball - 208 innings at 3B, 11 at 2B, 19 in LF, 1 in CF, and 22 at SS.
He's also been pretty dreadful with the bat in winter ball. 119 PA, .213/.269/.315 slashline - 2 homers, 5 doubles, 15 RBI, 0 steals, 8/18 BB/K ratio.
