Once MLB free agency begins after the World Series, Diamondbacks ace Patrick Corbin could be the top free-agent arm on the open market.

It's no surprise that he will have plenty of suitors, and one of them reportedly will be the Giants.

According to Nick Cafardo of the Boston Globe, Corbin is expected to draw a lot of interest from the Giants. And why wouldn't he?

Corbin, 29, is coming off the best season of his six-year career, and the Giants certainly want him away from an NL West opponent. This past season, Corbin went 11-7 with a career-best 3.15 ERA. He also tossed exactly 200 innings with a career-high 246 strikeouts and a career-low 1.050 WHIP. 

The left-hander also has been a menace against the Giants. He went 3-1 with a 2.27 ERA against them last season, including a complete-game shutout on one hit and eight strikeouts in his fourth start of the year. 

For his career, Corbin is 8-8 with a 3.04 ERA in 25 appearances against the Giants.

Cafardo also lists the Dodgers, Braves and Yankees as other suitors for Corbin. In the same report, Cafardo projects Corbin to sign a deal for at least five years at $20 million to $25 million per year.
