The bond between sisters is unbreakable, even if they are opponents on the softball field. The Romero sisters Sierra and Sydney have exemplified that in Oklahoma City this week with both Michigan and Oklahoma competing in the Women's College World Series.

Unfortunately for the eldest sister, Sierra's journey came to a close with Michigan's elimination on Sunday. But younger sister Sydney, whose Sooners will play in the winners bracket Sunday night at 9:30 ET, offered her congratulations to Sierra on a stellar four years in the maize and blue.

Sierra will go down as one of the best players in Michigan and NCAA softball history. The 2016 USA Softball Player of the Year led the Wolverines to three WCWS appearances and finished eighth in career home runs and fourth in slugging percentage in the Division I record book.
