Giants honor longtime fan with ALS as “Play Ball!” returns in his own voice

San Francisco’s Oracle Park took a slightly different route to the start of a Monday night game when the Giants replaced their usual pregame “Play ball!” moment with a more personal one for a longtime fan living with Lou Gehrig’s Disease. The team marked ALS Awareness Day with a ceremony tied to speech and sound, featuring Osiel Mendoza saying the familiar phrase in his own voice rather than through the typical text-to-speech route associated with the condition.

Mendoza has lived with ALS since 2017. The illness has taken away his ability to speak, and he previously relied on a device that reads his eye movements as he scans a virtual keyboard, converting his selections into text that then appears on a screen. According to the Giants, through a late-breaking change last weekend, he was able to produce and hear his own voice in a way that had not been possible for about six years.

The turnaround for Mendoza came from an overlap between his long involvement in Giants ALS observances and a sponsorship connection that brought a technology partner together with the team. The Giants said they arranged for Mendoza to return to Oracle Park for the commemoration, and that the sponsor helped create a voice profile that allowed him to speak as himself for the first time in years.

Central to the story is the speech technology used to translate language into audio with appropriate inflection. The Giants’ release identified ElevenLabs, a London-based company whose work includes text-to-voice systems designed to reproduce more than flat robotic reading, aiming to add natural emotion and delivery. MLB and the Giants have not suggested this is a cure, but the practical outcome was immediate for Mendoza’s pregame moment.

The Giants’ typical “Play ball!” format often includes specially selected kids from the community. For this game, they chose to preempt that routine and give the microphone to Mendoza, whose ability to say the phrase in his own voice was described as especially meaningful. In the Giants’ framing, the night’s message extended beyond awareness, using baseball’s most recognizable ceremonial line as a way to highlight how technology can restore something as basic as being heard.

The timing also matters in the broader league calendar. The Giants were honoring ALS Awareness Day ahead of their first home appearance following the league-wide event on June 2, a nod that the MLB ecosystem treats the day as more than a standalone media moment. By bringing Mendoza to the ballpark again, the Giants turned the commemoration into a game-day experience with a direct, human connection.

Looking ahead, the question becomes whether this kind of integration expands beyond awareness days. The Giants already have a recurring role for community and cause-related messages in their pregame presentation, and Mendoza’s experience suggests that sponsorship-linked technology can create durable ways to include fans who face communication barriers. For baseball, it is also a reminder that the sport’s public rituals can carry real-world meaning when they are tailored to the people they are meant to welcome.

If MLB continues to pair league-wide cause observances with on-field ceremonies like this, fans may see more moments that reshape what “Play ball!” signifies. Here, it meant that the game’s opening line, usually reserved for youth and tradition, temporarily belonged to a fan whose voice had been taken and, on this night, returned.
