Nathan Eovaldi is a classic risk-versus-reward case. 

The right-hander is coming off a Madison Bumgarner-esque playoff run in which he had a 1.61 ERA over 22.1 innings in helping lead the Red Sox to a World Series title. He also already has gone through two Tommy John surgeries.

The postseason dominance is hard to ignore, though, and the Giants reportedly are eyeing the starting pitcher in free agency, Nick Cafardo of the Boston Globe reported Sunday.

Cafardo noted that Eovaldi's preference is to return to Boston, and the writer lists the Brewers, Phillies, Braves, Angels, White Sox, Blue Jays and Padres as other teams showing interest. 

It's easy to forget Eovaldi still is just 28 years old -- he'll turn 29 in February. After making his MLB debut at 21 years old for the Dodgers in 2011, Eovaldi was traded one year later to the Marlins, and he already has pitched on five different teams.

He missed the entire 2017 season because of Tommy John surgery. 

Farhan Zaidi, Giants president of baseball operations, has a history of giving contracts to pitchers with injury issues in their past. And there's an occurring theme. 

As Dodgers general manager, Zaidi signed Scott Kazmir, Brandon McCarthy and Rich Hill to contracts worth three years and $48 million. Eovaldi, however, is expected to demand more.
