WTM’S PIRATE PLAYER PROFILES

2008
A-:  0-0-0, 5.00 ERA, 0.89 WHIP, 9.0 IP, 1.0 BB/9, 14.0 K/9
A:  2-2-0, 3.00 ERA, 1.13 WHIP, 24.0 IP, 1.9 BB/9, 13.9 K/9
A+:  2-0-0, 1.59 ERA, 1.06 WHIP, 17.0 IP, 3.7 BB/9, 11.1 K/9

Jackson made brief stops at three levels of the Cubs’ system, pitching well as a starter and reliever, and putting up high K rates.

2009
A+:  2-2-0, 1.64 ERA, 0.91 WHIP, 38.1 IP, 0.9 BB/9, 10.8 K/9
AA:  5-5-0, 3.70 ERA, 1.36 WHIP, 82.2 IP, 4.2 BB/9, 8.4 K/9
AAA:  1-0-0, 1.50 ERA, 1.33 WHIP, 6.0 IP, 4.5 BB/9, 6.4 K/9

The Cubs moved Jackson up to AA and he pitched fairly well there, although with a much higher walk rate than he’d had previously.  The team demoted him to high A in late July due to a rules infraction.  He dominated at the lower level.  He made one start in AAA at the end of the season.  After the season, Baseball America rated him the fifth best prospect in the Cubs’ system.

2010
AAA:  11-8-0, 4.63 ERA, 1.28 WHIP, 157.1 IP, 2.7 BB, 6.8 K/9

Jackson had a disappointing season in AAA.  He didn’t allow a lot of runners, but his stuff regressed, his K rate was low, and he had trouble with gopher balls, allowing 20.

2011
AAA:  8-14-0, 5.34 ERA, 1.54 WHIP, 146.2 IP, 2.8 BB/9, 6.0 K/9

Jackson went back to AAA and everything continued to go backwards.  Opponents hit .305 against him and his K rate dropped further.

2012
AAA:  3-7-0, 6.57 ERA, 1.71 WHIP, 86.1 IP, 4.5 BB/9, 7.9 K/9

Back in AAA for another season, this time pitching mainly in relief, Jackson’s performance went even further downhill.

2013
AA:  3-6-0, 3.16 ERA, 1.02 WHIP, 79.2 IP, 2.5 BB/9, 8.2 K/9
AAA:  1-1-0, 4.68 ERA, 1.60 WHIP, 25.0 IP, 4.0 BB/9, 7.2 K/9

The Cubs released Jackson at the end of spring training, but the Marlins signed him the next day.  He spent most of the season in the Marlins’ AA rotation, but he moved up to AAA late in the year.  He recovered somewhat.

Jackson pitched mostly well in spring training, including some longer outings.  He’ll start the season, though, in the AAA bullpen.  His experience in relief so far hasn’t been good, but it was very limited.
