PHOENIX -- Doctors believe rookie first baseman John Lindsey's broken hand will heal without needing surgery to insert a pin, Dodgers trainer Stan Conte said Sunday.

X-rays were sent to three hand specialists, Conte said, and the consensus was to hold off on surgery and take another X-ray when the club returns to Los Angeles for next weekend's final series of the season against Arizona.

Lindsey, who received his first callup to the Major Leagues earlier this month after a 16-year Minor League career, suffered the broken hand Saturday night when struck by a 92 mph fastball from Daniel Hudson in the Dodgers' 5-2 loss to the D-backs.

Lindsey has the hand in a soft splint. He hopes to be healed in time to play the second half of the Mexican winter league.

Dodgers trade Mattingly's son to Indians

PHOENIX -- Preston Mattingly, a Dodgers Minor Leaguer and son of incoming manager Don Mattingly, was traded Sunday to the Cleveland Indians for outfielder Roman Pena.

The move is seen as a fresh start for the 23-year-old Mattingly, who was given a $1 million signing bonus after the Dodgers drafted him as a supplemental first-round pick in 2006 (31st overall) but has struggled on the field in five seasons without advancing beyond Class A.

Hampered by hamstring problems, the right-handed Mattingly batted .194 at Inland Empire and .237 in the Arizona Rookie League, having been moved to the outfield after spending his first four seasons in the infield. His career batting average is .232.

"I'm happy for him and really thankful to the organization," Don Mattingly said. "He had kind of fallen off in playing time and to do this for him at this time was a gift for him."

Pena was a ninth-round pick by Cleveland in 2006 who also hasn't advanced beyond Class A. He hit .148 this year in only 24 games and has a career batting average of .244.
