The Boston Red Sox are still holding a postseason spot, but things have gotten a little murky. Red Sox Prospect Update: Tyler Uberstine, Luis Perales return, Ahbram LiendoTyler Uberstine is the most realistic option in Triple-A to help the Red Sox right now. Uberstine has a 3.73 ERA, .247 BAA, and 1.28 WHIP in 24 appearances (20 starts) between Double-A and Triple-A. If he’s not, that suggests the Red Sox have a plan for him in the not-so-distant future. Franklin Arias getting two weeks at the Double-A level to end his season was a great move by the Red Sox.
