Rubén Rivera Moreno (born November 14, 1973 in La Chorrera, Panama) is a professional baseball player, who is currently an outfielder for the Piratas de Campeche of the Mexican League. He played Major League Baseball for five different teams, from 1995 to 2003. His cousin, Mariano Rivera, is the long-time closer of the New York Yankees.

Rivera was signed by the New York Yankees in 1990. He made his professional debut with the Gulf Coast Yankees in 1992 and his major league debut with the Yankees on September 3, 1995. Rivera was highly touted as a prospect, being ranked as high as second overall amongst prospects by Baseball America in 1995, third in 1996, and ninth in 1997.

He played in 46 games for the 1996 New York Yankees. Though he was added to the postseason roster, Rivera only appeared in the 1996 American League Division Series during the 1996 postseason.

On April 22, 1997, he was traded with pitcher Rafael Medina and US $3 million to the San Diego Padres for infielder Homer Bush and minor leaguer Gordon Amerson and two players to be named later, who turned out to be the highly anticipated Japanese pitcher Hideki Irabu and minor leaguer Vernon Maxwell. It was supposed to be a deal to help both teams, but Irabu was a major disappointment for the Yankees, and Rivera turned out to be at least a minor disappointment for the Padres, as he was never able to get on base on a regular basis during his four seasons in the Padres organization, mostly with the parent team (including as a starter in 2000 and 2001), and his considerable power did not sufficiently compensate for that major failing. He was released shortly before the 2001 season.

Rivera is the capital of Rivera Department of Uruguay. It is located at the north end of Route 5, on the border with Brazil. The Brazilian city of Santana do Livramento is right across the border, only a street away of it. Together they form an international city of around 200,000 inhabitants.

On 7 May 1862 the town Pueblo de Ceballos was created in honour of the Spanish viceroy Pedro de Cevallos,. In July 1867 it took on the official name Rivera and was recognized as a city. The Brazilian town Santana do Livramento already existed just across the border.

In 1943, the Plaza Internacional Rivera-Livramento (see photo) was built to celebrate the Fifth Conference of the Commission Mixta for Mixed Limits and as a hope for the future integration of the two towns, claimed to be the only international square in the world. From 1851 to this day, inhabitants of both communities are free to move in both sides. Customs and checkpoints are located outside the cities. Today, duty free shops are one of the main economic resources of Rivera.

Brett David Harper (born July 31, 1981 in Salt Lake City, Utah) is former a first baseman in Minor League Baseball who currently plays with the Acereros de Monclova of the Mexican League. He is the son of former Major Leaguer Brian Harper.

Harper was drafted by the New York Mets in the 45th round of the 2000 MLB Draft out of Scottsdale Community College. He began his professional baseball career with the Kingsport Mets in 2001 and remained in the Mets farm system through 2007, raising as high as Double-A where played with the Binghamton Mets from 2004-2007. In 2004 with the St. Lucie Mets he was named the team's MVP and named to the mid-season Florida State League All-Star team, though he was unable to participate due to his promotion to Binghamton. In 2005, he finished third among all minor leaguers in home runs with 36 and he was again named to the FSL All-Star team. He also finished second in the FSL's home run derby.

In 2007 with Binghamton, Harper was named to the Eastern League Mid-season and post-season All-Star teams while hitting .296 with 24 home runs and 88 RBIs.
