Malher Tressor Moreno Baldrich (born 11 January 1979) is a Colombian former professional footballer who played as an attacking midfielder.

Named after classical music composer Gustav Mahler and famed French Footballer Marius Trésor, Tressor Moreno began his career in the youth ranks of Colombia's Tuluá.

As a result of his play with Nacional, Moreno began to draw interest from European clubs and in 2000 was sold to Metz in France.

Once his contract with Metz ended he returned to Colombia and played with Deportivo Cali for the 2004 season, where he scored a goal in a 3–3 draw in the playoffs against his old club Independiente Medellin on 20 June 2004.

While with San Luis, Moreno appeared in 89 league matches and scored 16 goals, including a brace against Tecos in the 2007 Apertura.

However, towards the final stages of the state league, Moreno would play less each time, and eventually he was dropped from the squad, never appearing for the club in the Campeonato Brasileiro.

[9] On 9 July 2012, after requesting more playing time and being second choice to Rafael Baca, the club's board decided to terminate his contract, and the previous day he stated on Twitter that he was "traveling to Chile for a new stage".

[12] In January 2013, he went back to Colombia and joined Atlético Huila,[13] scoring 5 times in 14 appearances, including a hat-trick and an assist in a 6-1 win over Deportivo Pasto.
