Manager Bob Melvin provided encouraging news on rookie third baseman Matt Chapman, who made a bang in his major-league debut series against the Yankees over the weekend. The knee infection that forced him to miss the first three games of the Astros series is responding to medication.
The swelling is down and Melvin expects Chapman to return Thursday or Friday, when the A's open a three-game series in Chicago against the White Sox.
Chapman went 3-for-14 against the Yankees. His first big-league hit was a two-run single in the eighth inning Friday night that gave the A's a 7-6 victory.
