SAN FRANCISCO - The Giants have made a habit in recent winters of "kicking the tires," so to speak, on as many free agents as possible. General manager Bobby Evans is committed to being thorough, but at times there is probably no need.
Hitters have made no secret of the fact that they prefer friendlier confines, and if you're a power hitter, you're going to ask Evans for a significantly larger check to play 81 of your games at the harshest power park in the majors. That's what makes Giancarlo Stanton, readily available via trade, so intriguing. But would Stanton be fully immune to the realities of AT&T Park?
The numbers, at least in a small sample, suggest he would. Stanton has played 27 games in San Francisco and taken 108 at-bats. He has nine homers, 11 doubles and a triple. His .676 slugging percentage at AT&T Park isn't far off his mark at Coors Field (.714), and his 1.048 OPS is higher than his OPS during the 2017 season, when he hit 59 homers.
The damage has been done in limited time, but the Giants clearly believe it's fully sustainable, and a recent study done by ESPN's Dan Szymborski backs that up. Szymborski ran his ZiPS projection system to estimate Stanton's stats over the next 10 years for a variety of suitors. The numbers in orange and black are overwhelming.
The projections have Stanton at 46.2 WAR over the next 10 seasons, including 7.1 in 2018 and 6.8 in 2019, the two seasons the organization should be focused on given Madison Bumgarner's contract situation. ZiPS projects Stanton at 46 homers next season if he plays for the Giants, followed by 43, 42, 39, 35 over the following four years. For comparison's sake, Brandon Belt led the Giants in homers each of the last two seasons and he has 35 total during that span.
Any sort of projection system needs to be taken with a huge grain of salt, especially with a player who has had injury issues in the past. But ZiPS believes Stanton -- who plays in a huge park already -- is a rarity, the kind of power hitter who can keep crushing well into his 30's and put up huge numbers even if he is limited by the realities of getting older and getting hurt. Szymborski's projections have Stanton playing just 102 games in 2025, but he's still projected to hit 23 homers, 20 doubles and post an OPS+ of 121. Even in the 10th year of the projections, ZiPS has Stanton down for 16 homers.
There are no sure things in this game, but as Evans continues to chase a blockbuster deal, he can be confident that Stanton is one player who should be able to provide power for years to come, no matter what AT&T Park does to hold hitters down.
