Tyler Matzek pitched two-hit ball for the first seven innings of his major league debut before faltering in the eighth, and the Colorado Rockies beat the Atlanta Braves 8-2 on Wednesday night.
The left-hander retired the first 13 hitters and 21 of 23 before allowing three straight singles to start the eighth. He is the third Colorado pitcher in the last six days to make his debut.
Matzek (1-0) allowed two runs on five hits and struck out seven in seven-plus innings. He also had his first hit and run scored. The Rockies had lost 11 of 12.
Julio Teheran (6-4) entered Wednesday with a 1.89 ERA, best in the majors, but Colorado scored three in the first on Drew Stubbs' RBI double and Corey Dickerson's two-run triple.
