MESA, Ariz. (AP) _ Sammy Sosa hit his sixth home run of the spring and Julian Tavarez pitched six scoreless innings Wednesday as the Chicago Cubs beat the Colorado Rockies 4-0.

Both benches were warned about beanballs in the top of the fourth inning, when Tavarez hit Jeff Cirillo with a pitch. The two players exchanged words as Cirillo walked to first base.

``He just asked me if I was OK,'' Tavarez said. ``I said, 'I'm OK.' I said I wasn't trying to hit him. I was ahead in the count.''

Tavarez (1-3), who pitched for the Rockies last season, allowed five hits.

``I'm very happy with the spring I've had,'' Tavarez said. ''(Pitching coach) Oscar Acosta has helped me out with a lot of things, talking about making pitches. That really helps. I'm able to use my slider now more and change speeds.''

The game was scoreless until two outs in the sixth. Bill Mueller then singled and Sosa followed by hitting a towering homer over the wall in left-center on a 2-1 pitch from Brian Bohanon.

Bohanon (1-1) pitched six innings, giving up seven hits and two runs.

The Cubs added two more runs in the eighth on Jose Nieves' home run and Todd Dunwoody's RBI double.
