Yahoo! News - Sosa Expected to Keep Hopping With Cubs
Sammy Sosa has until midnight CST Saturday to tell the Cubs if he's going to opt out of the final two years of his four-year contract and explore free agency. But it appears almost certain now that he's going to stay in Chicago.

Cubs left-hander Shawn Estes and center fielder Kenny Lofton filed for free agency. Left-hander Mark Guthrie filed after the club declined a $2.2 million option for next season. Other Cubs players who have filed for free agency include second baseman Mark Grudzielanek, infielder Tony Womack, outfielders Troy O'Leary, Tom Goodwin and Doug Glanville, and pitchers Antonio Alfonseca and Dave Veres.
