At any given year — should the Indios make it to the PRBL tournament playoffs — attendance to the team's baseball park and post -game celebrations tend to be particularly high because they usually coincide with the celebration of the patron saint feasts (fiestas patronales) for the city of Mayagüez; it is not unusual for a championship game to coincide with Candlemas (2 February) or Candlemas Eve.

Originally the Indios played their home games in the facilities of La Liga de París.,[3] now named the Santiago Lloréns baseball park, which has been in use since February 14, 1912.

The team moved from their previous grounds to then-new Isidoro García Baseball Stadium, located near the southwest corner of the city, later that year.

To make matters worse, the Isidoro García baseball stadium was in such a state of disrepair that it was literally unsafe for fans, players and field keepers.

Managed by Rene Lacheman, and provided with a powerful lineup that featured Ron LeFlore, Jim Dwyer, Kurt Bevacqua and José Manuel Morales in the 1-4 spots, the team barely made it to the playoffs, to consequently sweep the semi-final and final series.

This was a controversial move, since Méndez's extreme passion for the team was viewed with skepticism by some local fans, who considered him to be brash, arrogant, and motivated chiefly by money.

Objectively, though, Méndez not only attempted to raise fan support to a near-religious status, but was also responsible for five championships and three runner-up spots.

Many fans decided to have a love-hate relationship with Méndez, praising his business smarts and baseball acumen while hating him personally.

Méndez, who had grown tired of public criticism against him (and who faced a suspension from the LBPPR for assaulting a league peer), sold ownership of the team to Daniel Aquino, a native of the Dominican Republic who had earned a Mechanical Engineering degree from the nearby University of Puerto Rico at Mayagüez.

The fans' reaction to Aquino, who was once the owner of the Leones del Escogido of the Dominican winter league, made the backlash against Méndez pale in comparison.

Aquino had experienced considerable criticism in his home country for "watering down" the Leones' roster due to escalating payroll costs.

[9] Major League Baseball players who played with the Indios include Dennis McClain, Boog Powell, Bradin Hagens, Jim Northrup, Willie Horton, Mickey Lolich, Jack Morris, Dave McNally, Tommy Lasorda, Ron LeFlore, Kurt Bevacqua, Lance Parrish, Paul O'Neill, Jeff Brantley, Ken Caminiti, Zack Greinke, Doug Glanville, Harold Reynolds, Dennis Martínez, Danny Valencia, and Wally Joyner.

Local MLB stars who were also part of the Indios are Bombo Rivera, Willie Hernández, José Guzmán, Iván Calderón, Roberto Hernández, Iván Rodríguez, Bobby Bonilla, Wil Cordero, Jorge Posada, Eddie Rosario, and José Vidro.

Cordero was raised at the by-now razed Cócora section of town, which used to exist across the street from Isidoro García Baseball Stadium.

In December 2003 a panel of five local sportscasters announced their picks for an Indios de Mayagüez All-Time All Star Team.

A comment made on a broadcast by David Castro (see below) gave the team a moniker: "Los Indios de mi pueblo" ("My hometown's Indians").

The Indio, interpreted by Ervin Santana, is namely a costumed fan wearing a woolen poncho and feathered headdress who demands cheers from the audience for the local team and boos for the visitors.

[12] At one time during the late 1990s, the cheerleader sled past the dugout's roof and landed on a nearby staircase, fracturing a leg and three ribs.

After a long convalescence, the Indio returned to his usual chanting grounds on top of the stadium's first base dugout, calling for cheers wearing a cast and crutches.

Bompy, a mischievous kid, has its own Facebook page, and is a popular character among both teams' younger fans.

Soto's vocal inflections are so well recognized by fans that by just listening to his voice many can identify the difference between a pop-up fly and a hit before the ball actually lands.

A documentary about the team named "Los Indios de mi pueblo" and directed by Emmanuel Díaz, was issued in 2011.
