The Boston Red Sox once considered Jackie Bradley, Jr. a top prospect, but his value has plummeted around baseball.

Bradley has been great defensively, but terrible at the plate.

"Put it this way, at one time he would have been a featured piece in a deal, now he'd be a throw-in," a National League adviser said about Bradley's value. "He's an outstanding center fielder, but there's absolutely no sign of the hitting getting better. He can be pitched to and he doesn't seem to have the capacity to adjust. He gets fooled with offspeed stuff and he's getting overpowered by fastballs. The Red Sox have a tough call there. They've given him every opportunity."

Bradley has the seventh highest strikeout rate in the majors at 28.4 percent. He swings at pitches out of the strike zone 26.7 percent of the time and hits the ball on the ground at a 47.8 percent clip.
