Diamondbacks, Orioles, Cubs, Royals, Rangers, and Nationals pens

Let's get back to some volatile bullpens, starting with the Arizona Diamondbacks. Arizona has A.J. Puk (LHP, ARI) on the IL with an elbow problem that will keep him out into July. He feels better, but he is a long way away. Justin Martinez (RHP, ARI) is also on the IL with an elbow issue, but he is expected back late this coming week or early next week.

In the meantime, Shelby Miller (RHP, ARI) and newly returned Kevin Ginkel (RHP, ARI) have shared the saves. Ginkel is shaking off rust, and the first 4+ innings have been a mess. But he did convert a save this week. Miller has been better so far, but the team is clearly missing its best relievers. Here are the numbers so far:

ARI	SV	HD	IP	ERA	xERA	WHIP	K%	K-BB%	HR/9
Puk, A.J. L (IL)	4	2	8.0	3.38	3.04	1.25
