Cubs' Ian Happ: Out again with back tightness

Happ (back) remains out of the lineup for Monday's game in Philadelphia.

Happ was scratched from the lineup ahead of Sunday's 5-0 win over the Nationals because of lower-back tightness and will miss a second straight start Monday. He is considered day-to-day. Mike Tauchman will play left field and bat leadoff in Happ's stead.
