The bullpen still has a little wiggle room and with tomorrow being an off day it may become more clear. If any one's cut they will have tomorrow to discuss the roster to make a final decision and speak to the player with an empty locker room. I still think they're shopping relievers and with so many clubs in need of bullpen help I could see them pulling something off.
Wagner, Heilman, Wise, Feliciano, Sosa, and Schoneweis barring trade or injury are locks for the pen. That leaves one spot left, it appears to me that Sanchez just won't have the arm strength to start the year in the majors. Brian Stokes regardless of being out of options, looks like he pitched himself out of a roster spot. Joe Smith ( 9 ERA - seven innings) could get the last spot but he's been out pitched by Steven Register and the three non-roster invitees who are still in camp. Smith has re-vamped his delivery and needs time to work out the kinks before he's ready. Register could actually be one of those rare Rule V guys who sticks.
Joselo Diaz without much fan fare has pitched to the tune of a 1.23 ERA in seven innings, Diaz has a live fastball but struggles with control as evident by his five walks and five strikeouts. Ricardo Rincon looks solid ( 7-SO, 1-BB), he had that one rough outing against the Cards who were hitting everyone that day, he has a zero ERA except that game in which those four runs put it at 6.75. Finally Nate Field who seems to have made it this far by not doing anything to get noticed, his numbers are very average but at the same time he hasn't had a bad outing ( ERA 4.50, 5-SO, 2-BB).
