STILLWATER, Okla. -Davis Duren's bases-loaded single in the bottom of the 12th inning brought home the winning run for Oklahoma State as the Cowboys evened their series against Kansas with an 8-7 victory Saturday at Allie P. Reynolds Stadium.
The win snapped a four-game losing streak for OSU in Big 12 Conference play as the Cowboys improved to 6-11 in the league and 25-18 overall. The Pokes will play for their third conference-series win of the season in Sunday's finale, which is set for 1 p.m.
Saturday's extra-inning affair lasted four hours, 14 minutes and saw OSU erase deficits to tie the score in the ninth and 11th innings.
Duren was the hero with a 4-for-7, three-RBI day, while freshman southpaw Andrew Heaney tossed 1.1 scoreless innings to earn his fourth win of the season.
The decisive 12th inning began with Heaney giving up a base hit to KU's Brian Heere before getting a fly out and two strikeouts to end the inning.
In the bottom of the inning, Nico Rosthenhausler drew a leadoff walk, and Luis Uribe followed with a bloop single on a perfectly executed hit-and-run play to put Cowboys on first and third with no outs.
After an intentional walk to load the bases, Heaney struck out in his first plate appearance of the season before Duren stepped to the plate and delivered an opposite-field single to bring home the winning run.
OSU plated the first two runs of the game early, getting an RBI triple by Josh Botts in the second inning and a solo home run by Duren in the third, and the Cowboys took a 2-0 lead into the eighth behind the strong pitching of Brad Propst.
In his first-ever Big 12 start -- and just the second start of his career -- Propst kept the Jayhawks off the scoreboard and allowed only four hits through the first seven innings.
But in the eighth, Kansas rallied to take the lead. After a hit-by-pitch and a walk to open the inning, Brett Lisher laid down a sacrifice bunt to advance the runners. Propst struck out Brandon Macias for the second out of the inning, but a walk to Robby Price loaded the bases.
The Jayhawks would take advantage as Heere's two-RBI single tied the score and drove Propst from the game.
OSU called on Ian McCarthy out of the bullpen, but Tony Thompson blasted his fourth home run of the season, a three-run shot over the left-field wall, to give the Jayhawks a 5-2 lead.
The Cowboys still trailed by three heading into the bottom of the ninth, but with their backs against the wall, they responded.
Mark Ginther led off the frame with a double and then scored OSU's third run on a throwing error by Macias on a ground ball to shortstop by Rosthenhausler.
A single by Botts, who had a career-high two RBIs on the day, plated Rosthenhausler and made the score 5-4, and two batters later, Duren tied the score with an RBI single.
The Cowboys would then load the bases with just one out, but Kevin David grounded into a double play to end the threat and send the game into extra innings.
OSU failed to score in the 10th, leaving a pair of runners stranded after having a first-and-third-with-only-one-out situation.
Kansas (26-18-1, 7-9-1) regained the lead in the 11th with a pair of runs, getting an RBI double by Jake Marasco and a sacrifice fly by Lisher to go up 7-5.
But once again, OSU responded, with Ginther's two-out, two-RBI single tying the score in the bottom of the inning.
