Walker sidelined with strained left groin

LAS VEGAS -- Colorado Rockies outfielder Larry Walker was placed on the 15-day disabled list Saturday with a strained left

Walker has been sidelined most of the spring with the injury,
which occurred early in spring training and was aggravated in an
exhibition game on a checked swing. The move was made retroactive
to March 26.

A three-time NL batting champion and the league's MVP in 1997,
Walker hit .284 with 16 homers and 79 RBI last season.

The Rockies also released center fielder Cory Sullivan, who
injured his elbow earlier this spring.

Colorado's game against the Texas Rangers on Saturday was
canceled due to unplayable field conditions and further rain in the
forecast. Friday night's game between the teams also was canceled
because of rain.

The Rockies play an exhibition game Sunday in Sacramento,
Calif., against a Triple-A team, then open the regular season
Tuesday at Arizona.

Texas begins its season Monday in Oakland.
