Pirates 5, Cubs 4

OK debut: Starting pitcher Matt Garza made his Cubs debut, working 7 innings and giving up 12 hits and 3 runs. He walked none and struck out 12. Of the 106 pitches Garza threw, 80 were strikes.

Tough start: Center fielder Marlon Byrd was 1-for-5. After being the Cubs’ top hitter in spring training, Byrd is off to a 2-for-14 (. 143) start to the regular season.

Streak ended: When closer Carlos Marmol blew a save chance by giving up 2 runs in the ninth, it ended a streak of 6 scoreless innings by the bullpen to start the season. Cubs relievers ended last year with 28 straight shutout innings. Kerry Wood worked 1 scoreless inning ahead of Marmol Sunday.
