The Cubs signed another free agent. His name is Jose Veras. (More details about the deal are here)
He did save 21 games last season for the Astros and Tigers, so I'm guessing he'll get a chance to save games for the Cubs this year. He's not a young man (he's 32), but he has been a solid reliever in the National League for the past few years.
Hey, it's better than nothing. (I should get that slogan trademarked)
