THE SIDELINES : Senna Clocks Fastest Practice Run

<i> From Times wire services</i>

World champion Ayrton Senna of Brazil clocked the fastest time in his McLaren Honda today in the first practice session for Sunday’s Portuguese Grand Prix.

Senna was timed at 128.890 m.p.h. as he sped around the 2.7-mile Estoril circuit in one minute, 15.496 seconds. Red flags stopped the session three times because of spinoffs and collisions. To add to the problems, the track’s timing equipment failed because of a power outage.
