LSU’s Josh Smith (4), right, celebrates with teammates after hitting a go-ahead three-run home run in the fourth inning of LSU's 10-3 win over Air Force Academy Sunday in LSU's Alex Box Stadium. The home run put LSU ahead of Air Force, 5-2.

LSU entered the season as a consensus top-five team in all five major college baseball preseason rankings, ranked as high as No. 2 and as low as No. 5. 

The Tigers enjoyed a banner opening weekend that included the first individual no-hitter by an LSU pitcher since 1979 when Jared Poché held Army hitless in a seven-inning game Saturday. 

LSU finished its opening weekend undefeated for the ninth consecutive season, and 10th time in coach Paul Mainieiri's 11 seasons.
