MIRROR PERFORMANCE



If we go by their NPBL (Nippon Professional Baseball League) stats, Yu Darvish  and Masahiro Tanaka are the two best pitchers to leave Japan for Major League Baseball.  Hideo Nomo, Hiroki Kuroda, Hisashi Iwakuma and Daisuke Matsuzaka were all very good but not in this category.

YU   DARVISH

With a career ERA in Japan of 1.99 in 1268.1 IP over 7 years from ages 18-24 (2005-2011), Darvish sets a standard so high it seems unreachable.  His last 5 years (2007-2011) he pitched all under 2.00 ERA and his last 3 years were even better compiling 1.64 ERA in 616 IP.  

                    IP       ERA     H/9     HR/9    BB/9     K/9      K/W

2005-11    1268.1   1.99      6.5      0.40     2.40       8.9       3.70
2007-11    1024.1   1.72      6.1      0.34     1.94       9.5       4.90
2009-11      616.0   1.64      6.3      0.28     1.87       9.7       5.20

MASAHIRO   TANAKA

Tanaka also pitched ages 18-24 in Japan over 7 years (2007-2013) with 47 more IP for a total of 1315 and a 2.30 ERA.  However, his last 3 years he outpitched Darvish slightly and recorded the two lowest ERA'S of either pitcher in this time period with 1.27 in 2011 and 1.27 in 2013 going 24-0 in 2013.  Darvish posted a 1.44 ERA in 2011, only second to Tanaka.


                   IP         ERA      H/9     HR/9     W/9     K/9       K/W

2007-13    1315      2.30       8.1      0.45       1.88     8.28      4.40
2011-13      611      1.44       7.3      0.27       1.15     8.70      7.56

Other comparison stats in their last 3 years:

                        W-L     WHIP     GS      CG     SHOT      HR
Darvish           45-19    .913        76       28         10          19
Tanaka            53-9      .948        76       30         11          18

These performances almost mirror each other. They are very close.  Is it possible that Tanaka might have squeaked by Darvish in his last 3 years in Japan?
