- The pitchers who pitch in the various Winter Leagues are almost always relievers looking to get in a little extra work (and make a little extra money), usually for their hometown teams. There isn't really a great deal to be learned from their numbers, considering the extremely small sample sizes and generally low level of competition, but it provides an opportunity to take a look at some of the guys who will be competing for the last couple of bullpen spots, including the most recent addition to the White Sox.
- RHP Gregory Infante, who Baseball America recently rated as the 6th best prospect in the organization, is playing for Tiburones de La Guaira in Venezuela. He's appeared in 7 games, throwing 6 innings. He's had a bit of trouble with control, as he's walked 9, against 4 strikeouts, and has also hit 2 batters and thrown a wild pitch. Lack of control of his mid-90s fastball is often his problem, and we can safely assume that's the issue here, but he certainly has the stuff to be a set-up man.
- RHP Jhonny Nunez, who appeared for the White Sox in 2009, is with Tigres del Licey in the Dominican Republic. 2010 was a bit of a lost season for him, as he was sent to Birmingham to build up his innings and work on his changeup as a starter, and then moved up to Charlotte where he was inconsistent as a reliever and didn't merit a September call-up, though his peripherals were better than his results. He's experiencing a bounce back winter campaign, appearing in 11 games for 11 innings and has struck out 14 while walking only 2. His raw stuff isn't as good as Infante's - his fastball sits in the low 90s - and his ceiling isn't as high, but his slider and, to a lesser extent, changeup give him more advanced secondary offerings for the time being.
