Matsui left Saturday night's game against Arizona in the bottom
of the fifth inning. He had started the first 11 games of the
season at second base. He was hitting .361 with three RBIs and had
five stolen bases in five attempts.
The Rockies called up infielder Clint Barmes from Triple-A
Colorado Springs to take Matsui's roster spot.
Matsui, who has had back problems in the past, was acquired by
the Rockies from the New York Mets last June. He signed a one-year
contract with Colorado in the offseason.
