This week's BA Hot Sheet lists three Cubs: The Good: No. 3 BRETT JACKSON, CF CUBS Team: Double-A Tennessee (Southern) Age: 22 Why He's Here: .440/.548/.840 (11-for-25), 4 R, 1 2B, 3 HR, 5 RBIs, 6 BB, 8 SO, 1-for-1 SB The Scoop: There isn't a 70 grade anywhere on Jackson's scouting report, but he does so many things well and does it at a premium position that he has become one of the best prospects in the game. Even when Jackson is at his best, he'll do his share of swinging and missing, but he works deep counts and get on base at a high clip. He doesn't have plus power, but he should hit 15-20 home runs a year, which combined with his on-base potential and solid defensive abilities should have him banging down the door in Chicago by next season. The Not-Too-Shabby Cubs LHP Austin Kirk began his Independence Day by walking the first batter he faced. Then he set down 14 consecutive batters before another walk in the sixth, the only other baserunner he allowed in low Class A Peoria's 2-0 win over Clinton. Kirk, 21, completed his no-hitter with 10 strikeouts, breaking a three-game losing streak and evening his record at 5-5, 2.60. Kirk was a third-round pick out of high school in Oklahoma in 2009 . The God-Awful Hayden Simpson, lhp, Cubs: The Cubs' bucked conventional wisdom when they picked Simpson in the first round of the 2010 draft, after seeing him pitch well late in the season during the Division II playoffs. Up to now, you have to score one for conventional wisdom. Simpson has not come close to showing the 94-97 mph velocity he showed the Cubs last year, and his fastball has failed to bump 90 in some starts. He scuffled in the low Class A Midwest League in the first half of the season, going 1-6, 5.72, so the Cubs sent him back to the Rookie-level Arizona League. Facing significantly younger and less experienced players hasn't gotten him going either. He allowed five runs, five hits and walked two while striking out no one in 2 1/3 innings in his first start.
