Box Score 1 | Box Score 2 OKLAHOMA CITY (April 23, 2017) – Mason McAlister didn't get any run support Sunday until after he was done pitching, but that didn't seem to faze the junior right-hander from Yukon.

McAlister tossed a five-hit shutout and Garrett Wages drove in the only run with a fielder's choice grounder in the bottom of the seventh, lifting Oklahoma Christian to a 1-0 win over Arkansas-Fort Smith at Dobson Field.

Arkansas-Fort Smith rebounded to take the second game of the doubleheader – and the series win – with a 6-3 win in the second game, thanks to a seventh-inning grand slam by Jordany Santiago.

OC (25-20, 11-10 Heartland Conference) fell into fifth place in the league standings and now will need help if it is to qualify for the Heartland's postseason baseball tournament. The top four teams in the regular season make the tournament field. The Eagles have one more league series remaining, this coming weekend at fourth-place Rogers State. Arkansas-Fort Smith (25-16, 13-5) is tied for second.

"It's hard to win a series when you only score five runs in three games," OC coach Lonny Cobble said. "We were fortunate to win the one game. McAlister pitched great."

McAlister (4-3) and UAFS right-hander Tyler Nelson (5-5) staged an old-fashioned pitchers' duel in Sunday's opener. Nelson allowed only three hits and struck out six in 6 1/3 innings, while McAlister had seven strikeouts. Both worked out of jams in the early innings and seemed to gain strength as the game progressed. McAlister retired the last seven Lions he faced.

The Eagles finally broke the scoreless tie in the bottom of the seventh of the seven-inning game. Chad Kennedy worked a leadoff walk from Nelson and Zac Bycko's sacrifice bunt moved Kennedy to second base. UAFS intentionally walked Kolton Brown before Nelson walked pinch-hitter Luke Reynolds to load the bases.

Wages followed with a ground ball for which shortstop Drew Duncan had to move to his right to field. Instead of throwing home, however, Duncan threw to third base for a forceout, but that was only the second out and Kennedy raced home with the winning run.

It was OC's first 1-0 win since the university revived its baseball program with the 2008 season.

UAFS scored single runs in the first and third innings of the second game against left-hander Gabe Rodery, with Santiago and Nick Yoning providing the run-scoring hits. Jake Collins' two-run single to left field in the third scored Wages and Josh Garbrecht to tie the game and Kolton Brown's solo home run over the left-field wall in the fourth put OC up 3-2.

OC blew a golden opportunity to score in the fifth, failing to capitalize on two walks and two hit batsmen, with a failed squeeze play the main reason why.

That came back to haunt the Eagles in the seventh, when OC reliever Matthew Fusselman (1-2) ran into trouble. UAFS loaded the bases with no outs and after the Eagles recorded a forceout at home plate, Santiago hit his grand slam off reliever Garett Hill, making it 6-3.

UAFS reliever Clayton Whelchel (6-2) blanked the Eagles for 2 2/3 innings before giving way to Yoning, the closer, who did the same over 1 2/3 innings to pick up his seventh save.

OC will host Southwestern Oklahoma State at 6 p.m. on Tuesday in what will be the Eagles' final home game of the season.
