Your team looks pretty good for a 12 team league. How are you doing on stolen bases and saves though? That would be my only concern. Perhaps you could move Barmes while he's hot since you're already covered at 2b and ss and try to score a runner. I would also drop or trade 2 for one of your guys on the bench and pick up one of the closers on your ww. You only have Hermanson and Mota closing, one more would be good for your team. Consider also dropped Gonzalez outright, moving Castillo to 2nd and Barmes to SS and picking up a closer.
Check the availability of- Walker, Todd, Street, and follow the status of Weathers and Wagner of the reds, and Bernero of the braves to see if any of them land the closer role. I think Urbina's still closing for the Tigers at the moment too.
If you have a sec to check out mine
that would be cool. Hope I was some help to you.
