Nelson Cruz is having a very good season this year with the Mariners. We know this because:
1) He's on pace to hit 40 DINGERS,
2) His triple slash line is .302/.369/.547 (good for a wRC+ of 157), and
3) He was a member of the American League All-Star team (in infallible measure of greatness).
However, another thing that's quite impressive (if a little bit harder to find in the box score) is that Cruz has been the third best player in all of baseball this season at helping to improve his team's chances of winning.
