LOS ANGELES — While Prince Fielder took batting practice at Dodger Stadium before Wednesday night’s game, no fewer than nine stern-faced members of the ballpark’s security staff maintained a vigilant presence outside the Milwaukee Brewers’ clubhouse.

They were on heightened alert to prevent any recurrence of what took place the night before, when the burly slugger stormed across the hall after the Brewers’ 17-4 loss and attempted to force his way into the Dodgers locker room to confront reliever Guillermo Mota.

Mota hit Fielder with a fastball with two outs in the ninth inning, presumably as payback for Chris Smith grazing Manny Ramirez with a pitch two innings earlier.

‘‘I think Prince’s actions certainly were inappropriate and regrettable, and they will be dealt with appropriately by Major League Baseball,’’ Brewers manager Ken Macha said.

As was the case on Tuesday night, Fielder — who played with Mota in Milwaukee last season — didn’t offer any insight as to why he reacted so violently.
