With Jake Arrieta’s free agency looming, the Chicago Cubs may be positioning themselves to land another right-handed starter just in case. Marc Topkin of the Tampa Bay Times reported on Thursday that the Cubs are hiring ex-Tampa Bay Rays pitching coach Jim Hickey to the same position. Jon Heyman of FanRag Sports had reported Wednesday that whichever team landed Hickey could have an “enhanced chance” of signing Rays pitcher Alex Cobb, a free agent this winter, noting the close relationship between the two.
