Hazel Irvine introduces coverage of the second round of the women's Open, which is being staged on the Old Course at St Andrews. Home hopes will be pinned on Scotland's Catriona Matthew, who won this tournament in 2009 just 11 weeks after giving birth to her second child. That victory is the Scot's only major title to date, although she nearly claimed number two earlier this year, losing a play-off to Inbee Park at the LPGA Championship.
