The Tigers (12-2) look to win their 10th straight series when the rubber game gets underway at 1 p.m. Sunday. LSU junior left-hander Daniel Forrer (1-0, 4.20) is slated to go up against UH freshman righty Luis Flores (1-1, 3.18).

Olvey (3-0) turned in another dominating performance on Saturday, holding the Cougars to three hits, walking one and striking out five.
"He keeps giving you a chance to win when he fills up the zone with three different pitches for strikes," said LSU head coach Smoke Laval.
Offensively, LSU came alive with 11 hits after only collecting five Friday night against right-hander Brad Lincoln. Houston (8-7) committed three errors Saturday, all of which the Tigers capitalized on against starter Matt Farington.
Farrington (1-3), who limited the Tigers to a run on four hits last season, was chased in the second inning and eventually was tagged with the loss.
After Olvey sat down the first two batters of the game, third baseman Dustin Kingsbury reached when Stewart dropped a routine fly ball to right field. Designated hitter Brad Lincoln followed with a single, but Olvey erased the threat with a strikeout looking on second baseman Isa Garcia.
The Tigers wouldn't squander their chance to score on an error by the Cougars in the bottom of the first. Kingsbury misplayed a groundball at third, allowing first baseman J.T. Wise to take two bases with two outs. Stewart atoned for his fielding mistake with a RBI single through the middle, and two batters later he scored when catcher Matt Liuzza ripped an opposite field single.
LSU gave Farrington an early exit with a three-run second that increased the advantage to 5-0. Third baseman Will Harris singled was allowed to take third when centerfielder Bryan Tully misfired on his throw into the infield. The Tigers' top of the order -- Michael Hollander, Wise and Stewart -- all collected RBI singles. Farrington was responsible for all of the runs and left after 1.2 innings of work.
Meanwhile, Olvey was at the top of his game for the fourth straight week, retiring 10 straight from the end of the first into the top of the fifth. Even when the Cougars put the leadoff man on in the fifth, Olvey induced a double play groundball and then fanned Logan.
Another error by the Cougars in the fifth sparked LSU to two more runs. Sprowl led off with the Tigers' 10th triple of the season. Wise popped out to shallow right field. The second baseman Garcia then attempted to throw Sprowl out at third after the catch and fired it wildly down the line. Sprowl scored, and two batters late Stewart drilled his team-leading third homer of the season to give LSU a 7-0 cushion.
Laval elected to give two pitchers their first mound work of the season in the eighth and ninth. Senior right-hander Chris Cahill worked a scoreless eighth, and sophomore righty Will Goodwin saw his first action with a solid ninth.
"We are still feeling our way," said Laval. "We are going to give (senior right-hander) Justin Meier a bullpen tomorrow or he may come in relief to get him ready."
