Affectionately known as “El Pescadito” (The Little Fish), Ruiz spent the last two-and-a-half years with Guatemalan club Municipal. He’s been without a club since the Guatemalan season ended in May, but continued playing with the national team in World Cup qualifying over the summer, scoring both of their goals in a 2-2 draw at Trinidad and Tobago on Sept. 2 before bagging five in his final international match, a 9-3 win against St. Vincent and the Grenadines on Sept. 6.
Guatemala’s all-time leader with 132 senior caps and 68 goals, Ruiz ended his national team career with 39 goals in World Cup qualifying matches, the most for any one player in World Cup qualification history.
Ruiz, who began his MLS career in 2002 with the LA Galaxy and also spent time with the Philadelphia Union, is the 11th leading scorer in league history. He’ll be available immediately for first-place FC Dallas, who won the US Open Cup title on Tuesday night and will play at New York City FC on Saturday (7 pm ET; MLS LIVE).
