Rolex 24 Hour 20: Cadillacs lead
 |
| The #90 led at the 20-hour mark but does not have the speed to beat the Cadillacs unless they falter |
Although the standings below show the #90 Riley in the lead right at the 20-hour mark, the #90 had not stopped yet and the Cadillacs were back in front a few minutes after. Jordan Taylor leads in the #10 Cadillac after Max Angelelli put it on the #5 of Joao Barbosa on a restart and took the lead. Christian Fittipaldi is now in the #5 over 6-seconds back. Scott Sharp has the #2 ESM Nissan in fourth but he is over a lap behind for 4 hours left to run.
There is a great battle in GTLM between the #66 Ford GT with Joey Hand at the wheel and the #62 Risi Ferrari with James Calado at the wheel. Vilander had put the #62 Ferrari in the lead but Calado lost it back a few minutes ago. The #3 Corvette is not far behind and waiting to strike.
In GTD the #93 Acura NSX has taken the lead but the positions change with pitstops. Mark C. reporting for AR1.com
