With today’s big transactions, the Dodgers had to reconfigure space on the 40-man roster to make all the pieces fit.

Three players who have suited up for the Dodgers this year — Brandon Beachy, Chris Heisey and Chin-hui Tsao — were designated for assignment.

A fourth, Chris Hatcher, was moved to the 60-day disabled list, meaning that he can’t be activated until mid-August.

Michael Morse, who came from Miami today, was also designated for assignment. Taking on Morse’s contract helped the Dodgers acquire Mat Latos without sacrificing more in prospects than Jeff Brigham, Victor Araujo and Kevin Guzman.

Bronson Arroyo, who is recovering from Tommy John surgery, was placed on the 60-day disabled list, while infield prospect Jose Peraza was optioned to Triple-A Oklahoma City.

Any of the players designated for assignment could conceivably rejoin the organization by clearing waivers.

Beachy, recovering from his second Tommy John operation, allowed eight runs on 16 baserunners in 10 innings for the Dodgers this month. In his most recent start for Oklahoma City, Beachy allowed four earned runs in six innings.

Heisey went 4 for 26 with eight walks for the Dodgers, while OPSing .836 for Oklahoma City.

Tsao had a rough outing Saturday in New York that elevated his ERA with the Dodgers to 10.29 in seven innings. He also has a 3.000 OPS, thanks to his July 21 double in Atlanta in his first at-bat in 12 years.

Among those surviving the 40-man roster cut are recently acquired minor-leaguers Ronald Torreyes and Andy Wilkins.
