Shelby Miller and Jon Lester might be the first MLB duo to ever threaten perfectin on the same night.

St. Louis Cardinals rookie Miller and Boston Red Sox left-hander Lester allowed just one hit and faced only 28 batters — no walks, hit batsmen or errors — in complete-game shutouts Friday night, the first time that has happened in the big leagues, according to STATS, whose database goes back to 1921.

Lester was perfect — 17 straight outs — until Toronto’s Maicer Izturis hit a two-out double in the sixth inning. Lester, who threw a no-hitter in 2008, then retired the final 10 batters in a 5-0 victory.
