Outstanding pitching was the story in day one of the College World Series at T. D. Ameritrade Park in Omaha NE Saturday.

Oklahoma State's Thomas Hatch outdueled UC Santa Barbara's Shane Bieber as the Cowboys edged the Gauchos 1-0, and Arizona's Nathan Bannister handcuffed Miami in the nightcap as the Wildcats defeated the Hurricanes 5-1.

Hatch (9-2) ran his scoreless innings streak in the postseason to 23 consecutive and retired 22 of the last 25 batters he faced.  Hatch retired the leadoff man in all nine innings during his 112 pitch complete game performance.  The third round pick of the Chicago Cubs gave up five hits, walked one and struck out seven.

Bieber (12-4) took the hard luck loss, giving up six hits with no walks and six strikeouts.  But three of the hits came in the fourth inning and Garrett Burge's single up the middle knocked in the only run of the game.  Bieber, a fourth round choice of Cleveland, threw 98 pitches in his eight inning, complete game performance.

Arizona jumped out to a 3-0 lead in the first inning on just one hit.  Miami starter Michael Mediavilla walked one and hit a pair to load the bases.  He walked in a run and Jared Oliva delivered a two run single to get the Wildcats started.

That would be all Bannister (12-2) needed as he scattered eight hits over seven innings.  He walked three and struck out eleven.  Cameron Ming shut out the Hurricanes over the final two innings.

It was only the third time all season Miami was held under two runs.

The Hurricanes had plenty of chances, but stranded ten runners and were just 2-10 with runners in scoring position.

Arizona put the game away in the fifth inning on a two run double by Zach Gibbons down the line in right field to end the scoring.

UCSB and Miami will meet in an elimination game Monday afternoon, while Arizona meets Oklahoma State in a winners bracket game Monday night.
