The 41,166 fans at Wrigley Field weren't the only ones eager to see the radar-gun readings from Aroldis Chapman in his Cubs debut. The Cubs' players and manager Joe Maddon were peeking, too. Chapman didn't disappoint, striking out two of the three batters he faced in the ninth to preserve the Cubs' 8-1 Interleague win over the White Sox on Wednesday night at Wrigley Field.
