UAFS split its Heartland Conference series-opening baseball doubleheader against the Rogers State Hillcats on Saturday afternoon, winning the opening game 4-1 before losing the second game 10-9.

The Lions (25-10, 10-4) will play for the series win on Sunday when they play the Hillcats (20-16, 6-8) in a doubleheader at 1 p.m. at the Diamond Complex in Claremore, Okla.

UAFS maintained its one-game lead in the conference, but over a new second-place team. St. Mary’s (25-13, 9-7) slipped from second to third after losing its series against St. Edward’s 3-1. Lubbock Christian (26-12, 11-5) moved into second place after sweeping Texas A&M International.

In the opening game, senior right-hander Javon Rigsby allowed one run on six hits, walked one and struck out seven on his way to posting his fourth complete game in six starts.

UAFS collected 10 hits off Rogers State starter Tim Luce (3-6), who suffered the complete-game loss. Luce, who beat the Lions in the opening game of the Hillcats’ nonconference series earlier in the year, walked three and struck out eight.

Pitchford his second home run of the day and his 10th of the season in the second game as a part of the Lions’ 12-hit performance, but the Lions still left 11 runners on base in suffering the heart-breaking loss.

Pitchford was 2 for 5 with four RBIs, a double and a home run, Allen was 3 for 5 with one RBI and two doubles, designated hitter Anthony Seminaris was 3 for 4 with two RBIs and Cahill was 1 for 2 with one RBI and a double.
