Guerra was placed on the bereavement list Saturday, Dan Hayes of CSNChicago.com reports. Guerra will be forced to miss a minimum of three games following his placement on the bereavement list, and Eric Surkamp will be up to fortify the bullpen in the meantime. While Guerra has given up just three runs in his last 12 appearances, it does not look like he will get a chance to close for the White Sox this season.
