HOOVER, Ala. — Pinch hitter Chris Sciambra singled home Jared Foster with the tiebreaking run in the 11th inning as LSU won the Southeastern Conference baseball tournament championship with a 5-4 victory against Vanderbilt on Sunday at Hoover Metropolitan Stadium.

With one out in the 11th, Foster was hit by a pitch from Brian Miller (5-2). Sciambra pinch hit for Andrew Stevenson and Foster stole second before Sciambra sent him home by bouncing a single into center field.

Chris Cotton (4-1), who tied an SEC Tournament record with three saves, pitched 2.2 perfect innings for the victory.

The second-ranked Tigers improved to 52-9 and the No. 1 Commodores fell to 51-9.

LSU won its record 10th SEC Tournament championship and fourth in the last six seasons under coach Paul Mainieri.

Raph Rhymes led off with a single to left against starter Philip Pfeifer, but was thrown out trying to stretch it into a double.

Christian Ibarra walked a Ty Ross singled him to second. Foster hit a line drive to right that Yastrzemski could have backed up to catch, but he lost it in the sun and it got over him for a single.

Nate Fury relived to start the fifth and got into immediate trouble by yielding back-to-back singles to put runners on the corners. Ross threw out Yastrzemski trying to steal second as Xavier Turner held third.

Fury hit Harrell, struck out Gregor and walked Wiel to load the bases. Conde hit a long drive to deep left-center that Stevenson ran down, stretching out to snare the ball as he reached the warning track.
