HAMMOND — This time, Southeastern Louisiana did not have to worry about blowing a late lead to Tulane.

A year after losing twice to the Green Wave when they were one strike away from victory, the Lions took advantage of three errors in one inning by shortstop Stephen Alemais and jumped all over the Wave’s shaky relievers for one of the most lopsided victories in series history Wednesday night at Alumni Field.

Southeastern (5-3) went ahead for good with two runs in the fifth and broke it open with eight more in the sixth, winning 13-4 to give coach Matt Riser his first victory against second-year Tulane coach David Pierce. The Wave (4-4) beat the Lions in all three 2015 meetings.

Alemais made his first error on a wild throw after making a nice stab of a grounder to lead off the fifth. He followed with two more errant throws — none on easy plays — as the Lions went ahead 3-1.

The onslaught really started when Tulane freshman starter Ross Massey departed at the end of the fifth.

Carson Crites greeted reliever Tim Yandel with a mammoth home run to left-center to start the sixth — one of his three hits on the night. Yandel, Patrick Duester and Eric Steel proceeded to give up six more hits, walk two, plunk a batter and throw a wild pitch as Southeastern extended its lead to 11-1.

The implosion was nothing new for the Tulane bullpen, which had given up 19 runs in 27.2 innings through seven games, including four or more on four occasions.

Not much went right for the Wave after it tied the score at 1 in the fourth. With runners on first and third and one out, Grant Witherspoon was thrown out trying to steal second. Grant Brown struck out one pitch later.

Until the game was out of reach, Tulane’s only other opportunity to score came on Alemais’ leadoff fly ball in the first that center fielder Jacob Seward caught before crashing into the wall.

Alemais committed a fourth error in the eighth.

Southeastern starter Pat Cashman (2-0), who went 0-2 against Tulane last year, retired seven in a row spanning the fourth through the end of the sixth.

Massey (1-1), a Baton Rouge Catholic product and the brother of Tulane senior pitcher Alex Massey, took the loss in his first career start but had little to do with it. He struck out seven through four innings before getting victimized by Alemais’ errors in the fifth.

Southeastern went ahead 1-0 in the second when Crites singled, stole second and scored on Webb Bobo’s single. Those were half of the hits Massey surrendered. Once he left, the Wave was done.

The Lions even ran successfully on Tulane catcher Jake Rogers, who led the nation by throwing out 33 base-stealers a year ago. He bounced a pair of throws on his only opportunities.
