HOUSTON -- The Chicago Cubs, who have struggled against left-handed pitching all season, will give their right-handed hitting lineup another try Tuesday in an attempt to end a seven-game losing streak.

David DeJesus is the only left-handed hitter who will get a crack at Houston Astros left-handed starter J.A. Happ, who enters the game with a 4.96 ERA.

The Cubs have scored the least amount of runs against left-handers (21) than any other National League team, but they also have the fewest at-bats against left-handers. Their .225 batting average vs. lefties is 15th in the 16-team NL and their .291 slugging percentage is dead last.

DeJesus has been solid in the leadoff spot this season with a .367 on-base percentage, but he has just a .174 average against lefties this year with a .269 OBP.

DeJesus will lead off and play right field, followed by Reed Johnson (center field) and Starlin Castro (shortstop). Bryan LaHair, who has just one hit in his last 19 at-bats will get the day off and will be replaced in the cleanup spot by Alfonso Soriano (left field).

Joe Mather (third base) will bat fifth, followed by Jeff Baker (first base), Darwin Barney (second base), Blake Lalli (catcher) and Travis Wood (pitcher). For Lalli it will be his first career major-league start.
