The deal, likely to be completed within a few days, was first reported by ESPN's Peter Gammons.
Dodgers spokesman John Olguin said the team had no comment.
Perez was 7-6 with a 3.25 ERA in 31 starts last year. He led the
majors with 18 no-decisions and had the worst run support among NL
starters, at 3.30 runs per nine innings.
Shawn Green is headed to Arizona if the Diamondbacks can agree
on a contract extension with the slugger. Catching prospect Dioner Navarro and pitching prospect William Juarez would go to the
Dodgers as part of the trade, and the Dodgers also would give Arizona $8 million.
Deal with Bradley avoids arbitration
In addition, the Dodgers avoided arbitration with quick-tempered
outfielder Milton Bradley by agreeing to a $2.5 million, one-year
contract. Bradley, who made $1.73 million last year, can earn an
additional $750,000 in performance bonuses.
Bradley had career highs in homers (19), RBI (67), runs (72)
and hits (138) in 141 games with the Dodgers last season, although
he made as much news because of his temper.
Last month, Bradley served three days in jail in Ohio for
driving away while being issued a speeding ticket in 2003.
He faces a Feb. 22 trial in Ohio on a misdemeanor count of
disorderly conduct stemming from a Nov. 25 arrest for interfering
with someone else's traffic stop. If convicted, he could receive 30
days in jail or a $250 fine.
Bradley was suspended for four games in June for tossing a bag
of balls onto the field following an ejection, and suspended for
five more games in September after a bottle-throwing tantrum and
confrontation with fans at Dodger Stadium.
In October, the Dodgers decided not to discipline Bradley for a
clubhouse confrontation with a reporter.
"Milton was a key to our team's success in 2004, and we expect
him to be a major contributor again in 2005," Dodgers GM Paul
DePodesta said Tuesday. "He is an accomplished player with the
ability to be even more."
The 26-year-old Bradley has a .265 average, with 41 homers, 195
RBI and 48 stolen bases in parts of five major league seasons with
Montreal, Cleveland and the Dodgers.
Other Dodgers eligible for arbitration are closer Eric Gagne,
shortstop Cesar Izturis and Penny, who would have been traded to
Arizona in the three-team, 10-player deal with the Yankees that
collapsed last month.
