The consistency that has marked the beginning of the 2014 season for Cardinals young right-hander Michael Wacha continued Thursday against the visiting Cubs.

Wacha gave up three runs or less for his eighth straight start. He yielded just two runs on seven hits in seven innings to raise his record to 3-3. Wacha walked none for the first time in five starts and fanned five. His lone hiccup was a two-run homer to Starlin Castro in the fourth.

His next start is scheduled for Tuesday against Arizona.
