Jon Morosi of the MLB Network reports:
Hamilton is 27 years old and entering his second year of arbitration. He can become a free agent after the 2019 season. He made $2.625 million last year and estimated to earn about $5 million in arbitration this year.
San Francisco’s enormous outfield is obviously a good fit for Hamilton. That extra value to the Giants might make the return good enough for the Reds to consider this.
On the other hand, San Francisco has a lousy farm system. No obvious matches at first glance. Top prospect Christian Arroyo is blocked at SS (Brandon Crawford through 2021) and 2B (Joe Panik through 2020). But Arroyo just had hand surgery.
