Ellis spoke with USSoccer.com about the three moves:
"For Meghan, the message was ‘you’re not quite ready’. She’s been battling an injury, she’s been out from all physical activity for a long time and I certainly wanted to bring her in and have a look at her and see where she’s at, but Meghan and I both understand that right now she’s not ready to jump into that intense 90-minute environment. She’s working her way back and the Thorns will be a great platform where she can build herself back up.
"With Amy, again, making sure we give these players an evaluation is important. I think A-Rod in truth, is further ahead of where I thought she’d be after a year off. Not only is Amy playing her way back, but she is also processing a lot of new information from the end of the World Cup until now. The messaging was similar, keep progressing and return to your club environment and be ready to get after it in your pre-season.
"What I said to Sarah was that I was specifically looking at players that play her position, and digging a little deeper into that process meant taking another look at her. She is definitely someone we will continue to monitor. Sharpening up her speed of play is going to be a focus for her, but for sure, being in this environment has helped her understand the demands and pace of the international level."
Ellis chose the roster after a short training camp in Orlando, Florida.
"We've now had two camps together this year," she said, "and I've seen some good things across the board. Now we're looking to translate that into three games against fantastic opponents. We will be greatly tested and these are the moments where you learn the most about yourself which is exactly what we need right now."
