​On Saturday before their game against the Washington Nationals, the ​Philadelphia Phillies have activated outfielder ​Odubel Herrera from the injured list. 

To make room on the active roster, Philadelphia has designated outfielder ​Aaron Altherr for assignment. And it's, unfortunately, about time.

Two seasons ago, Altherr looked like a staple in the Phillies outfield, after hitting .272 with 19 home runs over 107 games. However, that big league success hasn't continued, and in just 22 games (29 at-bats) this season, Altherr is slashing .034/.067/.069 with one double and one RBI.

That's a small sample size this year, but he did not take advantage of the opportunities he was given.

Herrera has only appeared in 17 games this season prior to landing on the IL with a strained right hamstring. In 63 at-bats, Herrera has slashed .270/.319/.381 with four doubles, one home run and seven RBI.

This will probably be the end of the line for Altherr in Philadelphia. They have a surplus of outfielders, and even though he's been on the decline, expect some team to claim the 28-year-old off waivers.
