Anya Gostomelsky came within a mere three hundredths of a second of winning Israel's third ever medal at the World Short Course Swimming Championships on Sunday in Manchester. Gostomelsky finished in fourth position in the 50 meter backstroke final in a new Israeli record time of 26.84 seconds, fractions slower than bronze medal winner Kateryna Zubkova. Croatia's Sanja Jovanovic won the gold medal in a new world record time of 26.37s. Also Sunday, Gostomelsky, who finished fifth in the 50 meter butterfly and eighth in the 100m backstroke earlier in the championships, ended the 100m butterfly final in seventh place in a time of 58.02s. In other action in the pool on Sunday, Ryan Lochte set his fourth world record of the week at the short-course swimming world championships Sunday. Five other world marks were also established in the final day of the meet - boosting the total to 18. Lochte improved on his own 100-meter individual medley mark, set in the semifinals a day earlier. The American clocked 51.15 seconds, shaving 0.10 off his previous record. Lochte also set a world mark in the 200 IM and led off the Americans' world-record swim in the 400 freestyle relay earlier in the week. The other records Sunday were set by Markus Rogan in the 200 backstroke, Sanja Jovanovic of Croatia in the women's 50 back, Felicity Galvez in the women's 100 butterfly, Marleen Veldhuis of the Netherlands in the women's 50 freestyle and Russia in the 400 medley relay.
