Corbin reportedly met with the Phillies on Tuesday.
Corbin recently made the rounds of free-agent suitors, including meeting with Nationals owner Mark Lerner and general manager Mike Rizzo.
Patrick Corben, formerly of the Arizona Diamondbacks, reportedly elected to sign a six-year deal with the Washington Nationals, spurning the Yankees, who often were considered one of the frontrunners for his services.
Corbin is coming off one of his strongest seasons as a professional, which came at a flawless time considering it was a contract year. Corbin visited with the Phillies and the Yankees last week, and NY was reportedly unwilling to offer a sixth year.
USA Today's Bob Nightengale also reported that the Phillies have told Corbin they will not be "out-bid" by any other team interested in his services, a bold declaration that signals the Phillies are living up to the aggressive label they've been carrying the past month.
The Nationals, New York Yankees and Philadelphia Phillies were the three frontrunners during his free agency. Instead, they missed out on Corbin over a sixth year - a sixth year beyond the current Collective Bargaining Agreement - after spending the offseason saying they need rotation help.
Finishing fifth in the 2018 NL Cy Young voting, Corbin was the best pitcher on a staff that included Zack Greinke.
Patrick Corbin, 29, was incredible a year ago in his second full season back from Tommy John surgery (3.15 ERA over 200.0 innings, with a stellar 2.47 FIP), and he's going to be paid very handsomely in free agency for it (plus his relative youth).
Washington spending a boatload of money on Corbin may reduce their chances of signing Harper. He had a 3.81 ERA in 111 innings and impressed during Boston's postseason run.
MLB Trade Rumors ranked Corbin as the number three overall free agent in this years class. He compiled a 3.15 ERA, a 2.47 FIP, and a 1.050 WHIP.
