The Tigers' bullpen has felt a little like the wild west ever since the trade deadline. Kyle Finnegan has proven to be Detroit's most valuable trade deadline acquisition by far, but Rafael Montero, Codi Heuer, and Paul Sewald have yet to prove their worth. The Tigers' bullpen has a collective 2.84 ERA since Aug. 1 vs. their 4.16 ERA before. Tigers' altered version of pitching chaos is working despite confusing roster movesThe biggest weakness for the bullpen pre-deadline was the lack of swing and miss, which they've improved upon as a collective; they have a 28.1% whiff rate, up from 22.6%. Last year, one of the bigger elements on pitching chaos involved AJ Hinch declining to promise the closer to role to any one arm.
