MILWAUKEE (AP) — From college walk-on to major league starter, Chicago Cubs right-hander Alec Mills had to earn most every break he got. On the brink of big league history, he was happy to welcome this bit of luck: expecting to see two-time batting champion Christian Yelich in the on-deck circle, Mills looked over and saw his backup instead.

This one surprised just about everyone.

Mills cruised through baseball’s second no-hitter this season in just the 15th start of his career, completing the gem in a 12-0 romp over the Milwaukee Brewers on Sunday.
