Kuroda, 39 in 2014, went 11-13 with a 3.31 ERA in 201.1 innings (32 starts) with the Yankees in 2013. He pitched in Japan until he was 32 years old in 2007; he signed with the Los Angeles Dodgers for the 2008 season. Over his six years in the big leagues, Kuroda has posted a 3.40 ERA, a 1.18 WHIP, and a .249 BAA.
Kuroda was expected to either retire or return to Japan or re-sign with the Yankees this winter. The latter was the occurrence, and I am not surprised. Kuroda had a very strong 38-year-old showing, and he probably felt that he could do it again this season. With a $16 million deal, I think it was nearly impossible to see Kuroda backing down and returning to Japan.
