Louisville looks to break a two-game losing streak on Saturday as it heads to Pittsburgh to take on the struggling Panthers for the second time in 10 days.Louisville’s last victory came on Jan. 5 against Pitt (6-10, 1-4 ACC), a 75-72 home win. That game featured 16 lead changes in a thrilling second half. El Ellis paced the Cardinals (10-6, 4-2) by scoring 14 of his 18 points after the break.Ellis started off the year on the bench but got the starting nod in the Cardinals’ most recent game, a 79-63 home loss to North Carolina State on Wednesday. Ellis shot 1-for-6 from the field against the Wolfpack and finished with just three points in 16 minutes. Noah Locke, normally the team’s starting shooting guard, came in to replace Ellis and scored 13 points in 32 minutes.”El has been playing well — he’s got a long way to go defensively,” Louisville coach Chris Mack said. “Noah responded the way he needed to on the offensive end, but again, you can’t give points and then get points from the other guy. He’s got to be able to hold his water at that end of the floor. El was a bit more dynamic in terms of getting in the lane for our team.”Locke leads Louisville with an average of 10.9 points per game. Jarrod West, a transfer from Marshall, is the only Cardinal to start every game this season.Pitt seems to be showing some promise despite losing three of its past four games. The Panthers earned a hard-fought 69-67 win against Boston College on Jan. 8 but then fell apart Tuesday at Syracuse, losing 77-61. Pitt shot just 5 of 21 from the field in the second half against the Orange and committed 13 turnovers in the game.
