7 Brett Jackson, CF

Cubs outfielder Brett Jackson has been activated from the minor-league disabled list.

Jackson had been dealing with a toe injury, and was placed on the 7-day DL. Jackson was expected to compete for a role on the major-league club during the spring, but was limited by a shoulder injury, and was sent to the minors. 

Jackson reportedly had been working on a new swing that would help him cut his strikeout rate. Through 64 at-bats at Triple-A Iowa, Jackson has 24 strikeouts. 

Cubs outfield prospect Brett Jackson was placed on the 7-day disabled list at Triple-A Iowa because of a turf toe injury, according to the Des Moines Register. Jackson hasn't played in the outfield since April 15 and has been limited to pinch-hitting and DH duties the last few weeks.

"Frustrated," Jackson said. "I want to be out there helping the team win. Even DH-ing didn’t feel like enough. But it is what it is. We’ll move forward the best we can."

Prior to going on the disabled list, Jackson was batting .219 with two doubles, two triples, two home runs and nine RBI in 19 games. Unfortunately, his strikeout problems have persisted. Jackson, who struck out 158 times in the minors and 59 times in the majors last season, has struck out 24 times this year.

"We’re working on getting him in a better position earlier to put the ball in play," Iowa hitting coach Brian Harper said. "He’s making some adjustments -- starting to swing the bat better."
