<p>LONDON &mdash; The Cologne Open and the grass-court tournament in Den Bosch have been canceled as part of WTA calendar changes announced Friday.</p>
<p>The German tennis federation said the Cologne event was canceled because of the worsening virus situation. It had been scheduled to start May 15.</p>
<p>The Libema Open in ’s-Hertogenbosch was called off because of the pandemic and because the start of the French Open was recently <a href="https://apnews.com/article/french-open-sports-health-coronavirus-pandemic-tennis-09861b73bef3dbf3d5e16efe6f259263">pushed back</a> a week. The combined ATP-WTA Wimbledon warm-up tournament had been slated to begin June 5.</p>
<p>Libema Open director Marcel Hunze said the current restrictions made it impossible to host fans.</p>
<p>“Without the presence (of) enthusiastic fans the characteristic atmosphere of Libéma Open is missing,” Hunze said in a statement. “The decision of Roland Garros to move up a week would have further impacted our event."</p>
<p>Also, the tournament in Washington was moved to Gdynia, Poland, and changes from hardcourt to red clay. The event is scheduled from July 19-25.</p>
<p>The tournament in Prague was moved from May to a July 18 start and changes from clay to hardcourt. Serbia will host a tournament in Belgrade from July 26-Aug. 1 that was originally scheduled for Anning, China.</p>
<p>A hard court tournament was added in Cleveland for Aug. 23-29, leading up to the U.S. Open.</p>
<p>The WTA said it has expanded the number of smaller tournaments in a bid to provide more playing opportunities as the sport continues to come back from the pandemic.</p>
