WACO, Texas -- Baylor starter Austin Stone was too much to handle for No. 20 Oklahoma State as the Bears (13-9, 4-1 Big 12) claimed the series with a 4-1 win over the Cowboys (15-8, 0-2 Big 12) on Saturday. The junior tossed a three-hitter in his first career complete game.

The Bears followed a familiar formula and ended with the same score as Friday's series-opening win. BU scored in the first inning for the seventh consecutive game and Stone put it away from there to give the Bears their fourth series win in a row and third consecutive against a ranked team.

In the first, Lawton Langford led off with a walk and Brett Doe was hit by a pitch. An out later, Matt Menard hit what looked to be an inning-ending 6-4-3 double play, but OSU shortstop Donnie Walton bobbled the ball on the transfer to make the throw and had no play to load the bases. After Aaron Dodson grounded back to the pitcher for a force at home, Duncan Wendel took one for the team to force in a run. West Tunnell then delivered the crushing blow with a two-run single to left to put BU up 3-0.

OSU's lone run came in the fifth and was unearned as a Stone swinging strikeout wild pitch came around to score on a two-out error by Stone. Baylor got the run back in the bottom half on a Menard double play after Doe and Adam Toth singled to start the frame.

Improving to 3-1, Stone's final line was nine innings pitched with three hits, two walks, a season-high seven strikeouts and an unearned run. He also retired the last eight OSU batters.

OSU starter Mark Robinette (1-2) took the loss after allowing three unearned runs on two hits in 0.2 innings.
