Chapman, a 2014 first-round pick and non-roster invitee, went 1-for-3 with a two-run homer in Saturday's 4-3 Cactus League loss to the Cubs.
The A's are hoping to give Chapman some much-needed seasoning against big league arms this spring, and he got off to a positive start in that regard by launching a two-run blast off reliever Jose Rosario in the fourth inning. The 23-year-old did go down on strikes in another one of his at-bats, an area of his game that both Chapman and the A's are looking for considerable improvement in during his spring training tenure. Over 514 combined at-bats at the Double-A and Triple-A levels last season, Chapman whiffed at a 30.6 percent clip, a number that needs to come down if he hopes to take over the starting third base job in 2018.
