Sunday Twins: Santana, Berrios, and more

• Jeff Sullivan over at fangraphs has a nice write up on how Jose Berrios has improved over last year.
• Ervin Santana and Miguel Sano have been two of the key players carrying the Twins so far. Tom Froemming is worried that regression is coming, and we’re relying too heavily on them.

• The Twins haven’t considered extending closer Brandon Kintzler yet, tweets Darren Wolfson. Could be a trade candidate if the Twins are in "sell mode" at the deadline.
