The Cubs designated reliever Kameron Loe for assignment to open a 40-man roster spot for outfielder Ryan Sweeney, tweets MLB.com's Carrie Muskat. In related moves, the team optioned outfielder Dave Sappelt and promoted reliever Rafael Dolis. The Cubs now have six outfielders on the active roster: Alfonso Soriano, David DeJesus, Nate Schierholtz, Scott Hairston, Julio Borbon, and Sweeney.
Loe, 31, made only seven appearances this year for the Cubs before losing his 40-man roster spot. The Cubs had claimed him off waivers from Seattle in mid-April upon that team's acquisition of Aaron Harang. Last year, Loe posted a 4.61 ERA, 7.2 K/9, 2.6 BB/9, 1.19 HR/9, and 57.3% groundball rate in 68 1/3 innings for the Brewers.
Sweeney was signed to a minor league deal by the Cubs on April 2nd after being released by the Red Sox. The 28-year-old hit .337/.396/.627 in 91 Triple-A plate appearances to earn a trip back to the Show. Sweeney knows Chicago well. He was drafted by the White Sox in the second round ten years ago, and began his career with the South Siders before being traded to Oakland in the 2008 Nick Swisher/Gio Gonzalez trade.
