Walker, 23, is batting .255/.316/.546 with 26 home runs, 84 RBI and eight stolen bases through 97 games for Double-A Chattanooga.

Walker continues to defy the odds, striking out at an alarming rate but still posting prodigious power numbers. To be fair, he has never hit below .246 at any level in the minors. It is also worth noting that he has stolen at least eight bases in each of the last three seasons. He could get exposed at the higher levels, but he remains an intriguing prospect to say the least.

Walker is hitting .272/.328/.612 with 23 home runs for Double-A Chattanooga.

Walker continues to display outstanding power as he could lead all of the minor leagues in home runs. However, he continues to whiff too often as he's striking out in 37.2 percent of his at-bats. His walk rate isn't terrible at 7.2 percent, but he's likely going to need better plate discipline to thrive at higher levels. However, we could have made the same argument before he moved to Double-A. He should be promoted to Triple-A later this season and could be a September callup to Minnesota.

Walker, 23, is batting .249/.303/.532 with 12 home runs and 39 RBI through 46 games for Double-A Chattanooga.

Walker's power is legitimate, but he has fanned a staggering 68 times in 46 contests, while drawing just 13 walks. His lack of patience at the dish makes it very unlikely that he will be able to stick at the higher levels, but the power potential is difficult to ignore.
