I think Mauer is deserving. Maybe not first ballot, though. I mean, he's not a closer.
Come on, the guy was the best pure hitter in baseball for eight years. Except for his injury-riddled 2011 when he hit .287, and a .293 season in 2007, he hit .300 every year between 2006 and 2013, hitting .328 for those 1,012 games. In those seasons, he hit .347, .328, .365, .327, .319, .324.
Again, this is a catcher doing this. And he wasn't a bad defender, winning three Gold Gloves. So he didn't hit a lot of home runs. You had a catcher,
the premium position in baseball, the hardest one to produce offense at a high level, hitting .328 in his prime. Why is he not a Hall of Famer, yet Tony Gwynn, widely considered one of the best pure hitters of the modern era, if not the best, is? Gwynn hit .338. Didn't hit for power. Stole bases early, but that stopped when he hit 30.
Compare their career slash lines
Mauer .306 AVG/.388 OBP/.439 SLG/.827 OPS 124 OPS+
Gwynn .338 AVG/.388 OBP/.459 SLG/.847 OPS 132 OPS+
Gwynn's average for his career is much higher. Yet their on base percentage is identical.
Now, look at Mauer's prime.
'04-'13 .323 AVG/.405 OBP/.468 SLG/.873 OPS 135 OPS+
That's across 5,006 PAs. A catcher with 35% above league average OPS.
Why is there any question as to his worthiness?
