Alvarez pitched 1.1 perfect innings of relief Tuesday against the Phillies, striking out all four batters he faced.
The four strikeouts brought Alvarez's total to an astonishing 19 over just 8.2 innings since being called up less than a month ago. He's allowed just a single run over that span and figures to continue to see more big league innings if he keeps mowing down hitters at his current rate.
