The Cardinals felt the need to add another bullpen arm for the rest of the month of September, since Nicasio is not eligible for the postseason. He should help them down the stretch, but will he be enough?

This move was shrewd by the Phillies, as Alvarez is a pretty decent infield prospect. Philadelphia essentially received a player for free, since Nicasio was claimed off waivers last month from the Pirates.

Nicasio has middling fantasy value for the rest of 2017, while Alvarez gets a bit of a keeper-league spike due to a more favorable situation in the long run in Philadelphia.
