Answer
Domingo Guzmán's ERA with the Chunichi Dragons in 2004 was 3.76. This means that he gave up an average of 3.76 runs for every 9 innings he pitched. This was a good ERA for a starting pitcher in Japan, where the average ERA was 4.02 in 2004. Guzmán was a key member of the Dragons' pitching staff that year, and he helped them to win the Central League pennant.
