September was already important for Daulton Jefferies. As he was brought up to the Oakland A’s when rosters expanded, he essentially had a month to prove himself to the front office. Although he was getting a look in the bullpen, it would not have been a surprise to see Jefferies enter the rotation at some point before the end of the year.
That time is now. The A’s are putting Jefferies into their rotation, with James Kaprielian heading to the bullpen.
