The Phillies are trying to trade Howard and the $60 million remaining on his contract. The Royals are unlikely to take on that much money, but if the Phillies will pay most of the contract, the Royals could be interested in trading for Howard, who turns 35 on Nov. 19.
The Royals have had internal discussions about acquiring Howard, according to the report. They believe Howard could replace Billy Butler as the team's DH and be the 20-homer, 75-RBI threat they need to get back to the World Series.

Howard, 35, hit .223 with 23 home runs and 95 RBI in 2014, but his production has begun to dip below his salary, which stands at $25 million for 2015 and 2016.
