LOUISVILLE, Ky. -- Keanon Simon's RBI single in the top of the 12th inning gave Oklahoma State a 3-2 win Saturday over host Louisville in the NCAA Super Regional.
The Cowboys' victory forced a deciding third game in the best-of-three series. The final game will be 4 p.m. Sunday at Jim Patterson Stadium, where 4,138 fans turned out Saturday.
Oklahoma State (42-20), which has been to 19 College World Series, scored first on Corey Brown's solo home run in the fourth inning. It was a team-leading 22nd of the year for Brown, who was selected 59th overall by the Oakland Athletics in last week's Major League Baseball amateur draft.
Louisville (45-22), which has never been to a College World Series, took the lead with a pair of two-out runs in the bottom of the sixth inning. The Cardinals' No. 3 hitter, Daniel Burton, reached on third baseman Matt Mangini's throwing error, then took second when the errant throw went into the Oklahoma State dugout.
Isaiah Howes walked, then Jorge Castillo followed with a double down the right field line. Burton scored easily and Howes' wide slide allowed him to beat the tag of Oklahoma State catcher Ryan Flavell.
Louisville starter Justin Marks, the Big East Rookie of the Year, allowed only Brown's home run before leaving in the top of the seventh inning after being hit in the back by a line drive off the bat of Mangini, who was selected 52nd overall by the Seattle Mariners in the amateur draft.
Magnuson, the 56th overall selection of the Toronto Blue Jays, entered the game with nine saves and a 1.02 ERA. He came on in the eighth and retired the first three Cowboys he faced. But in the top of the ninth Oklahoma State leadoff hitter Ty Wright hit an inside fastball from Magnuson over the left field fence to tie the game and force extra innings.
Neither team scored in the first two extra frames before the Cowboys scored one run in the 12th. Oklahoma State's Tyler Mach reached on an error by Louisville third baseman Chris Dominguez, then advanced to third on Rebel Ridling's two-out bloop single to right field. Simon followed with a single under the glove of diving Louisville first baseman Daniel Burton.
Jordy Mercer (3-1), who played shortstop until taking the mound in the ninth, got the win while Magnuson (3-2) took the loss.
