Just as soon as Hamilton's bat gets going his base stealing efficiency has dropped. Over the past 10 games he has a .468 OBP and 6/4 SB/CS. The speedster has been thrown out 7 times in July after being caught 8 times the first three months. The drop in efficiency alongside the increase in OBP isn't entirely a surprise; by reaching base multiple times a game he gives opposing batteries more chances to get reads on him, and is more likely to be thrown out. Don't get me wrong, this isn't a knock against Hamilton. 19/7 isn't a bad ratio and swiping 19 bags in a month with a .414 OBP is never a bad thing. He now has 74/15 SB/CS in 2011 and his OBP is a promising .319.

Hamilton's double play partner is lighting it up with the bat and is quickly becoming the talk of the prospect world. In 33 games he is hitting .412 with only 8 strikeouts in 150 plate appearances. He provides little else, however, with a .125 ISO and 9/5 SB/CS. His ISO was .196 last year, mostly in rookie ball, so there is hope he can develop at least average power for the middle infield.
Liriano is no stranger to ugly stat lines. In his pro debut in the Dominican Summer League he hit .198 but followed up the next year with a .350 AVG. In 2010 he hit .271 in short season ball but then hit .191 in 50 games in Low-A and .220 in 14 High-A games. He started this year back in High-A and got off to a 7 for 55 start and was sent back to Low-A. He has hit .312 with 11 HR and 47 SB in 80 games and should be given a third shot at High-A. He is just over a month past his 20th birthday so the ugly numbers shouldn't scare you off him. He has very good 5 category potential and is quickly moving up among my favorite fantasy prospects.
Keyvius Sampson - Padres SP DOB: 01/06/91
Another one of my favorite fantasy prospects, Sampson keeps dishing out the solid outings. In 85.1 innings the Padres hurler has allowed just 56 hits. When he isn't inducing weak contact he is blowing the ball past batters with 10.3 K/9. He is also keeping his dominant pitch arsenal in the strike zone with 3.2 BB/9.
Jake Marisnick - Blue Jays CF DOB: 03/30/91
Marisnick is starting to add some power to his already strong combo of OBP and SB. He is hitting .312 with 10 home runs and 23 SB. He has 7 doubles and 4 home runs in July, the most for him in any month. They aren't huge totals but he consistently puts up similar numbers each month. I could see him posting those same numbers of 10 HR and 23 SB over a full season in the majors with the AVG being bumped down into the .280-.290 range. He is fairly large at 6'4", 200 lbs so he could add even more power as he matures. For now it's nice to see his pitch selection improving with 9/10 BB/K in July after going 8/20 in June.
