Baseball Prospectus has released its mid-season top 50 prospects list, and Keston Hiura has made a massive jump. The site now has Hiura as the 5th best prospect in all of baseball.

According to BP, Hiura is a star in the making. The staff suggests that in his prime, the second baseman could be a .300 hitter with a few 20 home run seasons. At worst, they guess that Hiura is Whit Merrifield because of his strikeout tendencies.

There’s no doubt that Keston is having a phenomenal season. He started at A+ with the Carolina Mudcats, but hit his way to AA going .320/.382/.529 with 7 homers in a hitters park.

He is in someone of a rut after injuring his thumb a few weeks ago with the Biloxi Shuckers. Since then, he has gone 2 for 36 over his last 9 games, dropping his average from .353 to .264.

Hiura was ranked at 32 in the site’s top 101 in the pre-season. We should continue to see major jumps from the second baseman as more sites release their mid-season rankings.
