GAME DAY

Second baseman Kaz Matsui returned to the lineup Wednesday after missing eight games because of a strained right foot. He went 3-for-4 with a stolen base and run scored in the Rockies' 7-4 loss to Seattle at Hi Corbett Field. . . . Catcher Chris Iannetta was 3-for-3 with a double and RBI. Todd Helton was 2-for-2 with an RBI and a walk, raising his average to .484.

TOUGH TIME FOR TOM

Left-handed reliever Tom Martin endured his third rough effort in four appearances, giving up two hits and two runs, blowing a save and suffering the loss while retiring only two batters. He has allowed seven runs in 3 2/3 innings and given up nine hits and four walks. Odds are, though, that he will at least start the season with the team. The only left-handed alternative is Mike Gallo, who figures to be at Triple-A Colorado Springs.

DELAY GAME

Left-handed pitcher Oscar Rivera showed the Rockies glimpses of hope for the future - but not enough to make an immediate commitment. No problem. Rivera's goal is to pitch in the big leagues, and his Mexican League team, Yucatan, has agreed to give the Rockies until June 1 to decide whether they want to pay $1.3 million for Rivera or send him back to his native country.

Rivera has been reassigned to the Rockies' minor league camp, where he has embarked on a strengthening program to help offset problems stemming from having pitched year-round in Mexico.

HE SAID IT

"We told him our focus is to turn him into a pitcher. It is not an issue of arm strength with him. He can throw 100 mph. He has to consistently throw strikes."

Marc Gustafson, Rockies' minor league director, on right-hander Juan Morillo, who has been working in side sessions instead of games since being sent to minor league camp.
