Cubs prospect Brett Jackson “has completely overhauled his swing”


Cubs outfielder Brett Jackson ranked among Baseball America‘s top 100 prospects in 2010, 2011, and 2012, but the big knock against him was a very high strikeout rate and questions about whether he’d be able to hit for a decent batting average in the majors.

This year Jackson showed very good power at Triple-A, but hit just .256 with 158 strikeouts in 106 games and then struggled mightily with the Cubs, whiffing in 59 of his 120 at-bats.

Carrie Muskat of reports that Jackson “has completely overhauled his swing” this offseason in an effort to cut down on the strikeouts, working with manager Dale Sveum and various Cubs coaches.

“I think he’s got a good base to work with going into the rest of the winter and going into spring training to understand the art of hitting, so to speak,” Sveum told Muskat. “Sometimes it gets lost and taught the wrong way.”

Obviously if Jackson can cut down on his strikeouts while not losing the other skills that made him a top prospect in the first place that would be great for the Cubs, but it’ll be interesting to see if having a 23-year-old “overhaul” his swing leads to unintended changes that hurt him overall.

David Phelps to undergo Tommy John surgery

Pitcher David Phelps has a torn UCL and will undergo Tommy John surgery, ending his 2018 season, the Mariners announced on Wednesday. Phelps was making brief one-inning stints in the Cactus League as he worked his way back from a procedure to remove a bone spur from his elbow last September. He said he felt the ligament tear on his final pitch against the Angels in his March 17 appearance.

Phelps, 31, was expected to set up for closer Edwin Diaz. The right-hander, between the Marlins and Mariners last season, posted a 3.40 ERA with a 62/26 K/BB ratio in 55 2/3 innings. He and the Mariners avoided arbitration in January, agreeing on a $5.55 million salary for the 2018 campaign. Phelps will become eligible to become a free agent at the end of the season.

As the Mariners noted in their statement, the expected recovery period for Tommy John surgery is 12-15 months, so this very likely cuts into Phelps’ 2019 season as well.
