At first, the drama played out beyond the field. The display for the radar gun at Chase Field resides on a screen in the right-field seats, above an advertisement for a bar and below the plaques commemorating the two retired numbers in Arizona Diamondbacks history. On Monday evening, as the Dodgers protected a three-run lead, the pixelated digits carried more weight than usual.
The gun tracked the speed of Kenley Jansen's cut fastball: 90 mph . . . 88 mph . . . 89 . . . 92 . . . 91. A pitcher of Jansen's pedigree rarely receives such scrutiny.
