The Cubs shored up the back end of their roster but gave up two top 10 prospects to do so.

Justin Wilson is in the midst of a career year, boosted by a career-high 35 percent strikeout rate and an unsustainably low .210 BABIP, but even expecting some regression to the mean, you can expect him to be an above-average reliever. He's also better than a specialist -- despite a lack of any real changeup, Wilson has been slightly better against right-handed batters in his career by OBP/SLG, with a higher strikeout rate against left-handed batters.
