Ms McShane, 27, from Silverbridge, was seriously injured in the attack in April 2010 and has been left unable to walk unaided and barely able to communicate.
Stacy Jurich was walking home with Miss McShane in Chicago after a night out when the pair were beaten and robbed in the city's Bucktown district.
The pair, who were both 23 at the time, were students at the University of Illinois.
The 27-year-old said she witnessed Miss McShane being struck with the bat.
She said she immediately fell to the ground, adding that "she was not moving" and "blood started coming out of her head".
Miss Jurich said she herself felt "excruciating pain" when she was struck on the head - for which she needed 15 stitches.
Ms McShane's mother Sheila, also testified. She described her daughter's condition since the attack.
She told the court Ms McShane, who was left with brain injuries, used to be a good sketch artist but now could only draw "scribbles". She said she had suffered infections and seizures since the attack.
The jury was also shown a video of Ms McShane struggling to take a sip of water.
Heriberto Viramontes, 33, is charged with attempting to murder the two women, aggravated battery and armed robbery.
His public defender said he was denying the charges and that his client was not the man who attacked the women.
He pointed out that Ms Jurich had not identified him as her attacker and that there was no DNA evidence to connect him.
But prosecutors claim his fingerprints were found on Ms McShane's belongings and a video shows him using Ms Jurich's credit card.
Viramontes' former girlfriend, Marcy Cruz is expected to testify against him as part of a plea deal in return for a 22-year sentence for admitting two counts of attempted murder.
