He appeared in only 15 games in his first three seasons combined, adding five complete matches in the club's 1958–59 campaign in the European Cup, including the 2–0 final win against Stade de Reims.

[1] In 1962, Ruiz signed for Deportivo de La Coruña on loan, being an undisputed starter during his only season but suffering relegation.

Released by the Merengues, he spent five of the following seven seasons in Segunda División, one of the two exceptions being 1964–65 with Real Murcia – top level relegation.

From 1979 to 1981, Ruiz was in charge of UD Las Palmas in the top flight, being sacked early into his second season, which ended in a narrow escape from relegation.

In 1984–85 and 1994–95, in the same division, he amassed 30 games for Elche CF and CD Logroñés combined as both teams eventually dropped down a level; the La Rioja side had no fewer than five coaches throughout the campaign, finishing with an all-time low 13 points.
