9. Brandon Crawford, 2011-present, 18.5 WAR
There he is! The current Giants shortstop comes in at ninth all-time in franchise history, already. You can definitely expect that number, and ranking to grow as he improves through, and into his prime. Crawford has taken massive strides in the past few seasons jumping from a 2.2 WAR in 2012 too a 5.6 in 2015, and 4.5 in 2016.
Crawford’s prowess at the plate has definitely helped but his defense has been a significant part of the equation. The back to back gold glove winner possesses a 10.7 career Defensive WAR according to Baseball Reference. By looking at his seasons overall, the years his Offensive Values and worth shot up (2015 & 2016), his overall WAR shot up as well. If he can keep up his offensive output to match that defensive output, Crawford could shoot up this list very quickly. The earliest Crawford could be a free agent is 2022. If he averages the same WAR he averaged over the last two seasons, for the remainder of his time under contract, he would have a 43.3 WAR with the Giants. That would put him third in franchise history.
One, that’s a testament to how good he’s been for the Giants. The other just goes to show how good some of the other players have been that weren’t around in our lifetime. There is only one more player that is on this list that has suited up for the San Francisco Giants, making the eye-test pretty difficult. But guess what, he’s up next! One good year from Crawford likely makes him the best short-stop in San Francisco Giants history, by virtue of WAR.
