1. The advanced metrics love him: Posey ranks 5th in all of baseball in fWAR (7.1), wRC+ (159), and wOBA (.403). It’s easy to turn this into a numbers humpfest – which let me tell you, I love a good numbers humpfest – but what Posey has done this year – is doing – is simply amazing/great/stupendous/other adjectives.
2. He’s hitting better than every qualified first baseman in baseball: Yup, that’s right. If you sorted through all the qualified first basemen in baseball – sorry, Joey Votto – you’d come up with 23 separate players. Posey is hitting better than every single one of them. Think about that for a second. A catcher, a position that’s traditionally fruitless on offense, is hitting better than the most offensive-oriented position in baseball. Prince Fielder, Albert Pujols, Mark Teixeira, Adrian Gonzalez … all hitting worse than Posey. This might be my favorite pro-Posey argument.
3. His second half is amazing: Just when you would think that catchers would be wearing down from the day-to-day wear and tear of the position, Buster Posey is peaking; since the All-Star break, Posey has batted .390/.467/.647. 600 points of slugging from your catcher is just absurd.
4. ‘dat heatmap: Look at this heatmap of Posey’s second half.
Or, in eBay user comment terms: A+++++ WOULD L@@K AT AGAIN@@!!1.
5. He’s Buster Posey: I mean, c’mon fer chrissakes, he’s Buster Posey! He leads the league in being Buster Posey. He does Buster Posey things every day. Just right now, while you were reading this, Buster Posey just saved five dolphins. Why? Because he’s Buster Posey, that’s why. I often think that ‘this guy is so important to the team’ trope that’s dusted off and brought out by sportswriters on a daily basis is silly, but allow me this one thing, because Buster Posey is the heart-and-soul of this team. He ascended during the World Series championship year; he suffered a tragic and disgusting injury last year; and he’s back this year and playing out of his gourd. This guy is so important to the Giants. He’s Buster Posey.
