No explanation for his exit

LOS ANGELES -- The Cubs' Kerry Wood left Tuesday night's game against the Los Angeles Dodgers after two innings Tuesday night
because of tightness in his right triceps.

The All-Star right-hander gave up second-inning home runs to Adrian Beltre and rookie Jason Grabowski -- his first in the major leagues. Glendon Rusch relieved Wood to start the third.

Wood was taken out as a precaution, the Cubs said, and was to be evaluated again Wednesday.

In the top of the second, Wood grounded out to deep shortstop
and ran hard to first base.
