Freshman pitcher Sarah Costlow and junior first baseman Carlee Gray each earned Atlantic 10 postseason honors, the league announced Tuesday.

Costlow’s record-setting freshman campaign earned her a spot on the All-Rookie team, while Gray was selected to the All-Academic team, collecting the second A-10 postseason award of her career.

Costlow achieved a team-best 16-17 record on the mound this season and set the program’s single-season wins record on Sunday, surpassing the mark previously set by Kara Clauss in 2012. The first-year ace finished the year with a 3.89 ERA and a team-leading 19 complete games and 190.2 innings pitched, more than any other freshman in GW history.

“Sarah has gained a tremendous amount of experience this season and will be so much better because of it,” head coach Stacey Schramm said in a release. “I am glad that she’s been rewarded for her contributions to the team this year because it is much-deserved.”

Gray was also selected to the All-Rookie team in 2012, but was honored this year for her 3.72 GPA and offensive play. She led all GW hitters with a .369 batting average, and ranked second-best on the team with 23 RBI, 48 hits and a .487 on base percentage. Gray is majoring in marketing and sport, event and hospitality management.

Defensively, the co-captain also committed only two errors in 46 starts, posting a .995 fielding percentage in her penultimate season.

“Carlee really stepped up this year in more ways than one,” Schramm said. “By the middle of the season, the coaching staff determined that she deserved to be a co-captain alongside of Tori Valos and Sam Dos Santos. She holds herself to high standards on and off the field while not allowing herself to get too high or too low. She is consistent in her work, attitude and effort and I’m thankful that she is being recognized for it.”

The Colonials finished their 2014-15 campaign at 25-23 overall and 7-14 in conference play, leaving them out of postseason play for the second season in a row.
