McKinstry was added to the Dodgers' 40-man roster Wednesday.
EDGE Analysis
The 24-year-old saw his first action with Triple-A Oklahoma City, where he hit .382/.421/.753 with seven home runs and 26 RBI over 26 games. McKinstry's addition to the 40-man roster protects him from the Rule 5 draft. While he showed promise at the Triple-A level, it's likely that the Dodgers will want to see a larger sample size before he makes his major-league debut.
