Roster Moves: Cubs send Jackson to the DL; Castro added to bereavement List

The Cubs placed Edwin Jackson on the 15-day disabled list with a right lat strain, an injury he has dealt with before. The move may be motivated by other factors as well, as Jackson has been the worst starter in baseball this season, posting a 6-14 record to go along with a 6.09 ERA.

Jackson said the injury had been bothering him for the last two starts. He tried to pitch through what he called “soreness”, but as he tried to put a little more on his fastball, it became clear he needed some time off.

They promoted Zach Rosscup from Triple-A to take his place on the roster. Rosscup is 2-0 at Iowa with a 2.10 ERA and a 1.10 WHIP in 30 innings for the I-Cubs. All of his appearances for Iowa have been in relief. This is his third call-up this season with the Cubs.

The Cubs also added Starlin Castro to the bereavement list following a family tragedy in the Dominican Republic. Castro will miss at least three, and up to seven games.

Logan Watkins was called up to take Castro’s spot. He made his debut in August of last year with the Cubs. Watkins has a slash of .256/.329/.364 at Iowa. He’s stole 23 bases, and been nabbed only four times. He will likely play at second in Castro’s absence, as Javier Baez will slide over and play at short, his natural position.
