According to early reports from ESPN.com, Nomar Garciaparra has a "ruptured" groin. The muscles in his groin have torn, at least partly, away from the bone, meaning he's off to the 15-day DL. The results of the MRI are not entirely known, but he will miss roughly 2-3 months (according to Yahoo! Sports), meaning the Cubbies will be missing their first-choice middle infielders Nomar and 2B Todd Walker until at least June.
So what does this mean? Let's see what happens. Jerry Hairston Jr., the man brought over in the Sosa/Orioles trade, needs to have an impact as an everyday 2B, something he's flirted with over the last couple of years. I'm not so worried about Neifi Perez - he's shown some grit since coming into the lineup, and regular play will only help his batting improve to the level of his steady and reliable defense in the hole.
Let's see what happens - middle of the 1st in St. Louis, Ramirez ended the inning with a double play, squandering a pair of singles by Perez and Patterson respectively. 0-0, Bottom 1.
