2018 MLB Mock Draft v 2.0 | FanGraphs Baseball

For this projection for the Giants to make any sense, you almost have to assume they envision Buster Posey's days behind the dish being numbered. Otherwise, collegiate 3B Alex Bohm might be a better pick from a proximate need standpoint. Singer would not be a disappointing pick for me but Swaggerty would certainly be an eyebrow-raiser giver Duggar's spring showing and visions of Heliot Ramos dancing in Giants fans heads.

2018 MLB Mock Draft v 2.0 | FanGraphs Baseball:

2. San Francisco Giants – Joey Bart, C, Georgia Tech Bart has long been connected to the Giants. They’ve scouted him arguably as much as any team has scouted any player this spring, and in recent weeks, he’s emerged as the heavy favorite at this pick, with Singer and South Alabama CF Travis Swaggerty representing backup options. GM Bobby Evans and other top club execs saw Mize (at Vanderbilt) and Bart (at Georgia Tech) two weekends ago while the team big-league team was in Atlanta playing the Braves. Skyscraping Kentucky RHP Sean Hjelle is a target in the second round.

The college pitchers, Singer, McClanahan, Gilbert appear to be falling somewhat and my guess is that hurts the Giants more since given the 25-man roster construction re: age, they would seem to crave more immediate help.

I like  Hjelle with the second pick, but you have to see who falls, especially among the college arms.
