Koji Uehara Top 10 Red Sox Moments | Red Sox Rewind 

He was absolutely more amazing than people realize, and if you weren't a Sox fan you missed an amazing season. For perspective, the record for ERA+ is 291 which is held by Pedro Martinez when he had a a1.79 ERA in 2000 and the career best is Mariano Rivera at 205. Koji had an ERA+ of 379 in 2013 (not trying to be Mr. Smarty pants, just a quick google search and baseball-reference).

Koji splitter was amazing

Back then, I thought Koji Uehara was literally the best signing the Red Sox made before the 2013 season. In 2012 with the Rangers, Uehara posted numbers close to 2013 despite missing nearly 3 months with injuries (1.75 ERA and only 3 walks, 4 home runs, and 20 total hits in 36 innings pitched).

100% I love "The Idiots" of 2004 like most but this became my favorite Sox team. Fear the Beards!

Koji posted similar numbers the year before he came to the Red Sox. In 2012 with the Rangers, Koji's numbers were a 1.75 ERA, 3 walks, 4 home runs, 20 total hits, and 43 strikeouts in 36 innings. He only pitched 36 innings (37 games) because he missed nearly 3 months with a strained lateral muscle injury.

Koji didn't have the longevity in the American League to compete for all time glory, but in is day he was the most dominant closer in the world for a few years.

and somehow nobody talks about that he K every last batters XD
