After losing Pablo Sandoval to the Red Sox, the Giants are casting a very wide net and have reached out to agent Scott Boras regarding top free Max Scherzer, reports Jon Heyman of CBS Sports. The Giants appear to be scouring the trade and free agent markets for upgrades, as Heyman reports that they’ve at least initiated talks with free agents Nick Markakis, Nelson Cruz, Chase Headley, Torii Hunter, Justin Masterson and of course Yasmany Tomas (their interest in Tomas has been well-documented). Beyond that, they’ve kicked the tires on Atlanta’s Justin Upton, and their interest in Jon Lester was reported yesterday as Sandoval looked to be on the verge of departure.

San Francisco’s interest in Scherzer isn’t terribly surprising. The team will bring back ace Madison Bumgarner and stable veteran Tim Hudson, but Matt Cain is returning from elbow surgery and Tim Lincecum’s reliability has taken s nose-dive in recent years. Both Ryan Vogelsong and Jake Peavy are free agents. Yusmeiro Petit was excellent in 2014 but totaled only 129 2/3 innings between the regular season and postseason. He’s certainly done enough to warrant a look in the rotation, but the lack of innings could be cause for concern.

In terms of their offensive targets, Heyman hears that the Giants are more likely to go with a cheaper option to replace Sandoval at third base, instead spending bigger on a replacement in left field for Mike Morse. He notes that they’ve taken a “close look” at Upton and have even reached out to former Giant Melky Cabrera, though one team source described Cabrera’s departure from the Giants as “awkward” to Heyman. (Cabrera was suspended for 50 games in 2012 to close out the season as the Giants pushed toward a World Series victory.)

Earlier today I looked at some post-Sandoval options for the Giants, listing several trade and free agent targets that the reigning World Series Champions could pursue.
