Gregory Polanco, OF, Pirates (Low-A West Virginia): 2-for-5, 2 HR (15), 2 R, 3 RBI.

Entering the year, Polanco was one of those players every team has a couple of – the super toolsy outfielder who one hopes will click. There was little sign of that in 2011, when he hit .237/.333/.361 in the Gulf Coast League, but few, if any prospects in baseball have taken a bigger step forward this year. There's absolutely nothing not to like about Polanco. A lean and wiry six-foot-four, the 20-year-old Dominican is the kind of player who catches your eye the second he gets off the bus, and then he shows a good approach, the potential for plus power, plenty of speed (40 stolen bases), and good defense in center. This is a five-tool guy actualizing, and rapidly, into an elite-level prospect.

Others Of Note:

  • Engel Beltre, OF, Rangers (Double-A Frisco): 2-for-4, 2B, HR (13), 2 R, RBI, BB, SB. Second-half surge continues with .298/.349/.553 line since the All-Star break; .259/.306/.439 overall.
  • Nick Castellanos, OF, Tigers (Double-A Erie): 2-for-3, 2B, R, RBI, BB. Talk of a big league call up has died down, but he's still hitting .306/.322/.444 in 56 Eastern League games.
  • David Dahl, OF, Rockies (Rookie-level Grand Junction): First-round pick has shown not only all five tools but plenty of ability as well; .380/.424/.615 in 45 games.
  • Delino DeShields, 2B, Astros (Low-A Lexington): 1-for-2, HR (10), R, RBI, BB, SB. Promoted to High-A Lancaster after the game; .298/.401/.439 in 111 games with 83 stolen bases.
  • Wilmer Flores, 3B/2B, Mets (Double-A Binghamton): 3-for-4, 2B, R, RBI, BB, K. Despite offensive improvements, there are still questions about secondary skills and ultimate position; .274/.324/.421 in 44 Eastern League games.
  • Scooter Gennett, 2B, Brewers (Double-A Huntsville): 3-for-3, 2B, 2 R, RBI, BB. Little second baseman with easy plus hit tool is 11-for-21 in last five games; .293/.334/.386 overall.
  • Billy Hamilton, SS, Reds (Double-A Pensacola): 2-for-4, 3B, 2 R, BB, 2 SB, CS. Has stolen 11 bases in his last five games to give him 133 on the year; just 12 short of the minor league record and hitting .273/.395/.384 since move to Double-A.
  • Slade Heathcott, OF, Yankees (High-A Tampa) 3-for-4, 2B, 2 R, 2 RBI, BB, 2 SB. Has lifted OPS 111 points in five games by going 12-for-23 with 21 total bases; .300/.377/.531 in 39 contests.
  • Mikie Mahtook, OF, Rays (Double-A Montgomery): 3-for-4, 2 2B, 2 R, RBI. 2011 first-round pick his hitting .308/.324/.523 in 17 games since moving up, but he's a corner outfielder who's college power has yet to translate.
  • Tyler Marlette, C, Mariners (Rookie-level Pulaski): 4-for-5, 3 2B, R, 3 RBI, K. Big bonus 2011 draftee is interesting talent with hitting skills and big arm, but catching ability needs work; 17-for-36 (.472) in August and .316/.342/.371 overall.
  • Adam Morgan, LHP, Phillies (Double-A Reading): 7 IP, 1 H, 0 R, 2 BB, 6 K. Impressive Double-A debut after striking out 140 over 123 innings in Florida State League; 22-year-old has outstanding command, and enough stuff to avoid classification as a pure finesse pitcher.
  • Joe Panik, SS, Giants (High-A San Jose): 2-for-4, 3 R. Ten hits in last three games and hitting .344 since the All-Star break; .293/.369/.412 overall is middle infielder with good approach and gap power.
  • Dorssys Paulino, SS, Indians (Rookie-level AZL Indians): 3-for-5, 2 2B, 3 RBI, 2 SB, CS. 17-year-old Dominican has been as good as advertised with the bat, but defensive concerns remain; .338/.393/.559 in 33 games.
  • Enny Romero, LHP, Rays (High-A Charlotte): 6 IP, 1 H, 0 R, 1 BB, 9 K. Left with big velo and big control problems will get plenty of time to figure it out, because when he's right, he's capable of lines like this.
  • Gary Sanchez, C, Yankees (High-A Tampa): 3-for-5, HR (3), 3 R, 3 RBI. First big game since promotion; .260/.319/.413 in 28 games with some minor progress defensively.
  • Trayce Thompson, OF, White Sox (High-A Winston-Salem) 4-for-5, R, 3 RBI, K. Has made big strides in cutting down on whiffs with .310/.365/.549 line in 46 games since the All-Star break; big tools are still there, and production is starting to match.
  • Dan Vogelbach, 1B, Cubs (Short-season Boise): 2-for-4, 2 HR (6), 2 R, 2 RBI, K. Beefy 19-year-old first baseman has impressed with hitting skills and power; five home runs in last four games and .356/.415/.746 in 15 overall since promotion.
  • Mac Williamson, OF, Giants (Short-season Salem-Keizer): 3-for-4, HR (3), 2 R, 2 RBI, BB. Third-round pick is huge (6-4, 240) and surprisingly athletic for his size; .327/.397/.577 in 13 games.
  • Justin Wilson, LHP, Pirates (Triple-A Indianapolis): 8 IP, 0 H, 0 R, 1 BB, 5 K. The rare eight-inning no-no due to rain; Fastball and curve are both a tick above-average, but often has trouble throwing strikes.

Love the descriptor "beefy."
No mention of Bogaerts? 2-5 with a HR in his AA debut...
Well it is obvious that Kevin has a bias against Bogaerts since he also left him out of the Top 50 list. Now that Machado is in Baltimore I can't think of a better position prospect in the minors today.
Profar says hi.
Yo, sgrcuts my 1st comment was sarcastic. If you failed to catch it, my second comment should have been the giveaway.
I was thinking the first sentence WAS sarcastic but then the second one seemed like it wasn't. If the whole was in sarcasm font, then +1.
KG, just start listing Bogaerts' line every game.
We caused the bias...Xander is innocent in all of this...
Kevin, what's the ETA on Bogaerts curing cancer?
Little Feat says not to Bogaerts that joint, my friend.
Dorssys Paulino, even by the lofty standards of the Dominican Republic, is an amazing name.
I saw Justin Wilson pitch the first 7 1/3 of a combined no-hitter April 29th in Durham. So this is the 2nd no-hitter he's been involved in this year!
I think DeShields was actually promoted to AA Corpus, not Lancaster.
