.Washington Nationals shortstop prospect Carter Kieboom said he will focus more on second base work in the offseason, given that he has more experience at shortstop. The last time he played the keystone regularly was when he was a small kid. Kieboom is the team's No. 2 prospect and could see his major league debut in 2019. He hit a combined .280/.357/.444 with 16 home runs, 69 RBI and nine stolen bases between High-A Potomac and Double-A Harrisburg in 2019. Kieboom should be stashed in dynasty/keeper leagues now.
