But 4.80m was a touch too far, albeit having shown she is looking well primed for the year, after an injury-plagued 2017.
Morris went on to win the championship with a new record of 4.95m, with Sidarova taking silver with 4.90m and Stefanidi bronze with 4.80m. Morris tried three times for new world record 5.04m but failed each time.
Kiwi Tom Walsh has successfully defended his world indoor shot put title, winning by almost a metre in a championship record 22.31m.
Walsh completely dominated the competition in Birmingham from start to finish, opening with an Oceania indoor record of 22.13m. He fouled his second attempt and then again recorded 22.13m in the third round, leading by 90cm as the top eight advanced to the fourth round.
The chasing pack closed the gap without ever threatening Walsh's mark. Germany's David Storl, a former two-time world outdoor champion, improved to 21.44m to clinch silver on a countback ahead of Czech Tomas Stanek in third. Brazilian Darlan Romani placed fourth with 21.37m, twice extending the South American record.
Knowing he had the gold medal in the bag as he headed to the circle for his sixth and final effort, Walsh unleashed a monster put of 22.31m, the longest of his career.
That was good enough for him to win the competition by 87cm and eclipse the championship record of 22.24m set by German Ulf Timmerman at the very first world indoor championships in 1987.
The 26-year-old Kiwi will be eyeing the world indoor record of 22.66m, held since 1989 by American Randy Barnes, and will be the hottest of favourites at next month's Commonwealth Games. The world outdoor record is 23.12m set by Barnes in 1990.
