Athletics manager Bob Melvin said Sunday that Chapman isn't likely to receive a promotion to the big leagues in the final month of the season, Carl Steward of the San Jose Mercury News reports.
Chapman turned heads with a three-homer game for Triple-A Nashville on Saturday, but that apparently didn't move the needle enough for the organization. Though he's shown exceptional power in the minors this season, Chapman has generally scuffled since being promoted to Triple-A, slashing .194/.284/.528 across 81 plate appearances.
