EAST LANSING, Mich. -- Sophomore Jimmy Pickens delivered an RBI single to unknot a 1-1 game in the bottom of the 11th and gave Michigan State a 2-1 upset of No. 13 Indiana in the first game of a three-game series.

The Spartans (19-11, 3-4) defeated their second ranked team of the season by taking down the Hoosiers (26-5, 8-2).

"It was a great win for our guys," Michigan State head coach Jake Boss said. "I'm really proud of them. They showed a lot of character, a lot of fight, they kept playing and never really got down. We got a big hit when we needed it and a couple big at-bats. It was a very good win against a very good ballclub."

Indiana scored its lone run in the third inning on a sacrifice fly.

Freshman Cam Gibson went 3-for-5 with three singles and Pickens had two hits for the Spartans.

Both starting pitchers were tagged with no-decisions. Joey DeNato of Indiana went 7.2 innings, allowing one run on eight hits and struck out a pair of Spartans. Michigan State's Andrew Waszak threw eight innings and allowed just one run on seven hits and struck out five IU batters.

"[Waszak's] our Friday night guy and he may not be a first round draft pick but he competes," Boss said. "And you know what you're going to get every Friday and that's why he goes on Friday. He made a statement for himself striking out the side in the first inning against a very good Indiana ballclub."

Michigan State tallied a run in the eighth, evening the game at one. Ryan Richardson hit an RBI single to right field over the outstretched arms of the second baseman, scoring Hunter Smith.

With two outs in the 11th, Anthony Cheky singled and Justin Alleman earned a walk in his first collegiate at-bat. Cheky stole both second and third, setting up Pickens with runners on the corners. Pickens sent a single up the middle, ending the game and clearing the Spartan dugout for the third walk-off win of the season.

Justin Alleman picked up his first career win and didn't allow a hit in two scoreless innings. Trey Popp also threw one scoreless inning, allowing one hit.
