The Mariners agreed to terms with supplemental rounder Taijuan Walker, according to the team. Ken Rosenthal of FOX Sports adds (via Twitter) that Walker will receive a bonus of $800K. Soon after the Mariners selected Walker with the 43rd overall pick in the draft, it became apparent that he would sign before long. The high school right-hander told reporters that he wanted to get started right away.
Mariners amateur scouting director Tom McNamara said in a prepared statement that Walker has an "above-average fastball and a high ceiling," potentially as a "top-of-the-rotation type of pitcher." Baseball America ranked Walker 70th among draft-eligible players and noted that he has "taken off" since he began focusing on his pitching.
Walker becomes the ninth player drafted in the supplemental round to come to terms with his team; you can check out the complete list here.
