CINCINNATI (AP) - Sometimes, left-hander Aroldis Chapman can’t help but peek.

A murmur will go through the crowd when one of his express fastballs hits the catcher’s mitt and the estimated speed is shown on the ballpark’s scoreboard. The Cincinnati Reds pitcher says he’ll occasionally glance back to see which big number is showing.

The Cuban defector hit an even bigger number in his second major league appearance Wednesday night. He twice hit 103 mph on the radar gun during another perfect inning against Milwaukee that included a pair of strikeouts.

In two innings, he has retired all six batters on only 19 pitches _ 10 of them clocking in at triple digits. His fastball topped out at 102 mph in his debut on Tuesday.
