His younger sister Samantha, a third baseman for Valdosta State's softball team, hit for the home run cycle in a doubleheader against Albany State earlier this week -- a solo home run, a two-run homer, a three-run homer and a grand slam.
Posey, a junior, hit half of the Blazers' eight homers and drove in a total of 11 runs (including an RBI double) as they swept the doubleheader 13-0 and 16-0, with both games ending in 4½ innings.
She hit a two-run homer in the first game and a solo shot, a grand slam and a three-run homer in the second game.
She wasn't aware she had achieved the feat until afterward.
"I did not know that," Posey said, according to the Valdosta Daily Times. "That's pretty cool. I felt really good.
"You go in the [batter's] box and sometimes you're really comfortable. That's when I know I'm going to hit," Posey said, according to the report. "I felt really comfortable in the box."
If that's the case, perhaps Posey has been feeling comfortable all season long. As of Monday, she was batting a team-high .468 with eight home runs and a .909 slugging percentage for the Division II Blazers (31-6, 16-5 Gulf South).
