Add default.xml
in app/design/frontend/your-theme-namespace/yourtheme/Magento_Sales/layout
with following content
<?xml version="1.0"?>
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
<body>
<referenceBlock name="top.links">
<block class="Magento\Framework\View\Element\Html\Link\Current" name="customer-account-navigation-orders-link-top" after="my-account-link" >
<arguments>
<argument name="path" xsi:type="string">sales/order/history</argument>
<argument name="label" xsi:type="string" translate="true">My Orders</argument>
</arguments>
</block>
</referenceBlock>
</body>
</page>
My Orders link will appear as in the image.
I hope this will be helpful.
