The weirdest bullpen stat of them all

Something unusual happened last night and I'm not talking about KC winning back to back to games for the first time this season. What happened was this, the bullpen gave up their first run of the year after taking over for Kyle Davies. Despite being an abomination all year they have simply been money every fifth day. After last nights ninth inning adventure they now have a 0.87 ERA in 10.1 innings when Davies starts, for the rest of the rotation they have 7.51 ERA in 50.1 innings. So not coincidentally the Royals are 3-1 when Davies takes the hill.

Date	IP	H	R	ER	BB	SO
April 9th	3	3	0	0	3	5
April 14th	2.1	0	0	0	3	3
April 20th	2	2	0	0	0	2
April 26th	3	5	1	1	1	1
Total/Davies starts	10.1	10	1	1	7	11
Total/non-Davies starts	50.1	64	44	42	33	38
Total	60.2	74	45	43	40	49

This is strangely baffling because there really doesn't seem to be a logical explanation. Soria has pitched just 2.1 of those innings which means his less talented colleagues have gotten the job done as well. I guess it's just one of those baseball things but it makes absolute zero sense.
