OAKLAND -- It became almost a running joke earlier this season how little run support Jeff Samardzija was getting with the Chicago Cubs, especially when the right-hander had a 1.68 ERA through 11 starts but a 1-4 record to show for it. Wednesday, Samardzija’s new team scored five runs on his start day -- a total they’ve reached only three times in their last 10 games -- but it went for naught in an 8-5 A’s loss to the New York Mets.
