Santos first began his work on Patriots games as the color commentator working with play-by-play announcer Bob Starr from 1966 through 1970 on WBZ 1030. After Starr's departure from the Boston market following the 1970 NFL season, Santos took over as play-by-play announcer and handled that assignment for nine years. From 1980 through 1990, the Patriots' broadcast rights shifted—first to WEEI 590, then to WHDH 850—and Santos spent 11 seasons out of the team's radio booth, with John Carlson, Curt Gowdy and Dale Arnold serving as play-by-play announcers for those flagship stations. Santos returned as the Patriots' radio voice in 1991 when WBZ radio regained the team's broadcast rights. From 1972 through 1978 and from 1990 through 2011, his partner in the booth was former Patriots kickerGino Cappelletti, except for the opening eight games of the 2001 Patriots season when Cappelletti was hospitalized with an illness and former Patriots player Peter Brock substituted for Cappelletti. Cappelletti retired from his position prior to the 2012 season and was replaced by former Patriots quarterback Scott Zolak. In addition to his work at WBZ, Santos commentated games for the Boston Celtics, Boston Breakers, Providence Friars basketball, Penn State Nittany Lions football, and Boston College Eagles football. On January 10, 2009, Santos announced his retirement from WBZ radio, effective at the end of that month. He continued as Patriots play-by-play announcer when the team's network switched from WBCN to the new WBZ-FM, branded as "The Sports Hub". In April 2012, Santos suffered a bout with pneumonia and was briefly hospitalized, calling into question his future as Patriots play-by-play announcer. He nonetheless announced he would return for one final season as Patriots broadcaster, retiring after the 2012 NFL season. In April 2013, Bob Socci was announced as Santos' replacement. Santos' 36 years of service made him the longest-serving announcer in the NFL, tied with Merrill Reese of the Philadelphia Eagles; he was also the final announcer who remained from the American Football League era.
