Heyward on fire

What's the name of this prospect? Explosivo!

Jason Heyward, OF, Braves (Double-A Mississippi)
Thursday's stats: 4-for-6, 2 2B, HR (1), 2 R, RBI
In his first 10 Double-A games, the 19-year-old outfielder is batting .417/.476/.639 (average/on-base/slugging). He's suddenly developing at a tremendous pace, and one has to wonder if he's suddenly in line for a September look, as one of the reasons he stayed with the big league team so long this spring is that manager Bobby Cox just liked watching him play so much.

Enjoying his new home

Brandon Allen, 1B, Diamondbacks (Triple-A Reno)
Thursday's stats: 1-for-3, HR (2), R, RBI, BB

Allen spent most of spring training with the White Sox's big club, proving that last year's breakout was a very real thing, indeed. That was enough for the Diamondbacks to trade Tony Pena for him earlier this year, and Allen has continued to rake, now going 6-for-14 with 13 total bases and six RBIs in his first five Pacific Coast League games.
