The Chicago Cubs' bullpen hasn't had a hierarchy this clear in quite a while.
Daniel Palencia, flamethrower extraordinaire, has settled into the closer's job quite nicely, even amidst a string of somewhat shaky outings.
Caleb Thielbar, Drew Pomeranz, and Taylor Rogers have united to form a brilliant triumvirate of southpaws, all capable of pitching anywhere in the middle innings whenever a gauntlet of left-handed batters steps to the plate.
Andrew Kittredge has been hit or miss in his time with the team since being acquired at the trade deadline -- following blow-up outings with immaculate innings -- but he's long been capable of holding down the seventh or eighth inning.
