The Rangers have reached an agreement with Elvis Andrus through at least
2018. An announcement is expected later this week after Andrus completes his
physical. The contract extension is for eight years but Andrus can be a free
agent after four years.
There is a vesting option for a ninth season.
8+1(vesting option)的合約
第四年打完後可跳脫成為自由球員
可以把這份延長合約想成是60M/4Y (?)
