Rietti (Italy), Sep 10 (IANS/CMC): Jamaica’s Rusheen McDonald has set a new meet record in the rarely-run 300 metre race at the final IAAF World Challenge meet of the season here.

McDonald ran a world leading 31.97 seconds to highlight a good day for Jamaicans, who won four of the six events they participated in Sunday.

McDonald, who was running the distance competitively for the first time, broke the 34-year-old record of 32.23 seconds set by Italian great Pietro Mennea, who died earlier this year.

McDonald, a member of the Jamaican silver medal-winning men's 4x400m relay team at the recent IAAF World Championships in Moscow, beat two Italians to the line, as Diego Marani was second in 32.85 seconds, and Lorenzo Valentini third in 33.18 seconds.

Three other Jamaicans were in winners row- Carrie Russell ran a personal best 22.62 seconds to win the women's 200m; Rasheed Dwyer won the men's 200m, and Stephenie-Ann McPherson won the 400m.

Russell, who was part of the Jamaican gold-medal winning 4x100m team that set a new national record 41.29 seconds at the World Championships in Moscow, continued her impressive late season showing by winning in 22.62 seconds, beating her previous best of 23.93 seconds, as another Jamaican, Aleen Bailey, was fourth in 23.45 seconds.

McPherson, who was fourth in the women's 400m at the World Championships, led a Jamaica first-and-second finish in the one-lap race, as she clocked 50.00 seconds, with Keliese Spencer running a personal best 50.19 seconds for second, and Christine Day finishing fourth in 51.78 seconds, behind France's Floria Guei's (51.70 seconds).

The meet, in its 43rd staging, was held in honour of the late Mennea, who won the 200m gold medal at the 1980 Moscow Olympics, and held the 200m world record for nearly 20 years.
