You've heard a ton by now about Byron Buxton and Miguel Sano. They are among the top prospects in all of baseball, and for good reason. You've probably heard a good deal, too, about Eddie Rosario -- another top Twins prospect. Aaron Hicks and Oswaldo Arcia still fall under "prospect" territory, even though both have spent considerable time with the big league club this year. And there are other young hitters in the minors that suggest a bright future could be ahead for Minnesota.

None, however, have as many runs batted in as Adam Brett Walker II -- a prospect about whom you might not have heard as much. In fact, nobody in all of minor league baseball has as many RBI as Walker.

He was the first to reach 100, cracking a homer and a triple on Sunday to sit at 102 knocked in. He's played the entire season at low-A Cedar Rapids. Even though we've seen two Kernels games in person this season, his name barely registers with us. (Walker was 0-for-4 in one and didn't play in the other, so there's that). When we saw him in late May, Walker was putting up decent power numbers. He had 10 homers through the first two months of the season.

He went deep just twice in June, but he mashed 10 bombs in July and has another four already in August, leaving him with 26 on the season.

Sano grabs a lot of the power headlines, and rightfully so considering he has 29 homers and 90 RBI between high-A and AA ball.

But don't forget about Walker -- a third-round pick from 2012 who will turn 22 shortly after the season ends -- when compiling a list of intriguing power prospects.
