An unearned run in the top of the ninth was the difference as Oklahoma State completed a 4-0 weekend at the TD Ameritrade Classic by defeating Creighton 6-5 Sunday evening.
Oklahoma State (32-11) won its fifth straight game while Creighton (24-10) had its six-game winning streak and eight-game home win streak come to an end.
Down 1-0 in the second, Creighton struck for two runs on a single by Federico Castagnini. Michael Blatchford drew a one-out walk, then Brennan Murphy laced a single to left to put runners at first and second. With two down, Brad McKewon was hit by a pitch to load the bases to set it up for Castagnini.
The Bluejays extended their lead to 3-1 in the fourth on a sacrifice fly from Alex Staehely. McKewon and Castagnini opened the inning with back-to-back singles, allowing Staehely to connect for his 13th career sac fly.
Austin Groth walked the first two Cowboys in the fifth before giving way to Mark Winkelman and Oklahoma State would tie the game on an RBI grounder and a single up the middle from Saulyer Saxon.
OSU scored two in the top of the eighth inning to take a 5-3 lead. Tanner Krietemeier hit a one-out double. Winkelman got Randy McCurry to pop out before a bad-hop single off the bat of Victor Romero bounced over Reagan Foweler's head at first and plated Krietemeier. OSU made it 5-3 on a Zach Fish double to score Romero.
Creighton would battle back to even the score in the bottom of the eighth. Consecutive singles by Murphy and Ryan Fitzgerald preceded a sacrifice bunt that put both men in scoring position. OSU then called on closer Brendan McCurry to slam the door. He would strike out Castaganini before Jake Peter's double to the right-field corner scored two.
Rick Stover reached on an error to start the Cowboy ninth. Pinch-runner Jarrett Higgins moved to second on a bunt and to third on a wild pitch before scoring on Donnie Walton's double off Mark Lukowski (4-2).
McCurry retired the Jays in order in the bottom of the ninth to improve to 6-2.
