If you're looking for a prospect with serious helium, meet Nolan Arenado.

Arenado, the Rockies' second-round pick last year, began the year in extended spring training, but since he joined low Class A Asheville two weeks ago, the 19-year-old third baseman has shown why his bat is so highly regarded.

Arenado has a hit in 11 of his 12 games and is batting .380/.414/.560 with as many walks (five) as strikeouts. Sure, he's benefiting from a hitter-friendly environment in Asheville, so the power numbers will probably come down, but Arenado's hitting is no mirage. He's a balanced hitter with barrel awareness and an excellent approach at the plate, with power that could come down the line. If he keeps this up, he just might be the Rockies' best position prospect by the end of the year. A shortstop in high school, Arenado has made a smooth transition to third, where he's projected as an above-average defender.

It's Too Easy To Make Bad Puns

We've written about Angels center fielder Mike Trout's looming breakout since spring training, but it's hard to stop talking about him given what he's doing seemingly every night in the Midwest League. Trout, a first-round pick in 2009, collected his sixth consecutive multi-hit game yesterday for low Class A Cedar Rapids with four singles in Lansing. His .376/.451/.566 batting line in 51 games is stunning enough for an 18-year-old in that league, but when you consider that he's also 28-for-32 stealing bases, well, that might be the most impressive year of anyone in the minors right now.

Midwest League Assault

While his season hasn't been quite as electric as Trout's, Nick Franklin has propelled his stock considerably as a 19-year-old shortstop in the Midwest League. Franklin, the 27th overall pick last year, blasted two more home runs yesterday for Clinton, giving him 11 on the year. That puts him third in the league in home runs and first among infielders. With a .325/.369/.589 line in 52 games and a clean, compact swing, it's hard not to be excited about Franklin's full-season debut. You can read more about Franklin in Tuesday's Prospect Q&A.

He's Back, With Bat

The Indians' Lonnie Chisenhall is back with Double-A Akron from a shoulder injury, though he hasn't played third base yet and has stuck to DH. The good news is that Chisenhall has come back hitting well, including yesterday when he went 2-for-4 with a home run. Like we said before, the overall numbers don't look great now, but there's no real cause for alarm here, it's just a matter of him getting healthy.

Reese At Peace In Double-A

Mets second baseman Reese Havens has acclimated to Double-A just fine, thank you. Havens had one of the best games of his career yesterday for Binghamton, hitting two home runs in a 3-for-4 game at Bowie. He's only been with Binghamton for nine games since his promotion from high Class A St. Lucie, but it's looking like he could be an offensive-oriented player in the middle of the diamond if he can stick at second base.
