Hildenberger had to get sent down. he's a mess out there right now, he's fooling no one...he's had one good outing in his last six, and it's not like they've all been high leverage situations. His May has been abominable, so time to go back down to Rochester and see if he can get straightened out.
I don't think you panic on the Twins' bullpen yet, though. Parker, Rogers, and Harper have all been fine. May has been a little wobbly at times, but should be fine (unless he keeps walking 4 per 9...). Let's see what we can get out of Duffy, Magill, and Morin this month to see if they can fill up those 6th-7th inning jags. I'm liking the Ks out of Duffy & Magill, not loving the WHIP. I'm still not convinced Morin is anything other than Just Another Guy, but he's done enough so far that it's worth looking at him longer.
But I do hope the twins are willing to explore Kimbrel as an option. I'm assuming they're not willing to surrender the pick and basically everyone is out right now until June on him absent a major injury to a closer with a contender. But this team is showing enough competitiveness that they need to consider what it might take to bring him in. Now we as fans also need to realize that he probably doesn't pitch for 2 weeks after signing in MLB...and might struggle with control for a while too while he gets into game shape.
The Buxton question is interesting. He's playing very well: hitting with power, solid OBP, defense is stellar as always, and he's staying on the field. Are you better off moving up up where he gets more ABs, maybe gets the team off to fast starts...or do you follow the old "if it ain't broke, don't fix it" rule? I honestly don't know. Would it really make that much impact?
I'll admit, I'm just happy that he's hitting. He could put up a 5 bWAR season and really put himself back on the map. I love this guy, he's one of the most fun players the twins have had and I feel lucky we get to watch him play.
