In case you missed it, Clayton Kershaw was the roster move for Scott Elbert, but that’s only a roster technicality. Because the roster expansion begins on Monday — but mostly Tuesday, because Las Vegas has another game on Monday — the Dodgers can option Kershaw now and still bring him back in time to make his next scheduled start on Tuesday night against San Diego. The 10-day rule — all players optioned to the minors must stay a minimum of 10 days unless a major-league player is placed on the DL, and that exception is limited to a pitcher replacing a pitcher or a position player replacing a position player — isn’t in effect because the PCL season ends Monday and Las Vegas isn’t going to the playoffs.
