It sounds as if that scribbled cocktail napkin at the Winter Meetings in Nashville could be in permanent ink.

According to multiple reports, the Phillies could be on the verge of trading closer Ken Giles.

First comes a report from Jim Salisbury, CSN Philly, tweeting that talks between the Phillies and Houston Astros surrounding Giles are "heating up."

Salisbury also tweeted that the Phillies have pushed back their media availability for Wednesday and that could be in relation to a possible trade with the Astros.

Jayson Stark of ESPN then let us in on that names have been discussed and that a current return package for Giles would be centered around right-hander Vincent Velazquez. Two additional prospects would also be included in the deal.

The Phillies have been mum on any trade involving Giles, they have taken the stance of trading him only for a deal that's on their terms. Giles is young and cheap enough to remain under club control while the team rebuilds under a new regime.

Velazquez, 23, is regarded as a flame-thrower and projects as a No. 2 starter in the major leagues. He also would come with less than three years of big league time.

The New York Yankees are also said to be interested in Velazquez.

The asking price on Giles is considered a high one, but the market has dictated such a price. The San Diego Padres were able to get a substantial package for an older, more expensive closer in Craig Kimbrel.

Giles currently has just one-year of MLB service time and would not be eligible for arbitration until after the 2017 season.
