This is what you want to see from Mitch Keller.
The Pirates lost 1-0 to the Orioles last night, with Keller giving up the lone run and getting no support from his offense. The right-handed starter pitched six innings, allowing eight hits and one walk, with one strikeout.
Keller has been outstanding since adding a new sinker to his repertoire. He started heavily incorporating the sinker heavily on May 25th. In 12 starts with the new pitch, he has a 3.14 ERA in 71.2 innings.
For some perspective on how much of a shift this is for Keller, consider his inconsistent past.
