O’Halloran was a 6'2", 205 lb. catcher from Toronto. Born on the 21st of May, 1968, he was selected in the 32nd round of the amateur draft in 1988 by the Toronto Blue Jays out of Orange Coast College. He spent the 1989 campaign with the St. Catharines Blue Jays in the low-A New York Penn League, hitting .283/.338/.404/.742 over 69 contests, with 27 RBI. He joined the high-A Dunedin Blue Jays in 1990, playing in 121 games and hitting .284/.339/.428/.767 with 11 round trippers, and 75 RBI.
1991 would see O’Halloran remain in Dunedin for the first 20 games of the season, where he collected a statline of .284/.346/.351/.697 before moving on to the double-A level Knoxville Blue Jays. He played 110 games that season, plus 117 the following year with Knoxville, with an aggregate statline of .264/.312/.368/.680 with a combined 10 home runs, 87 RBI, and 18 stolen bases. O’Halloran spent his 1993 at the AAA level with the Syracuse Chiefs in the International League, appearing in 109 contests at .267/.296/.357/.653. He played with the Eastern League Portland Sea Dogs for the largest part of the 1994 campaign, appearing 104 times and hitting .263/.331/.405/.736. The Marlins called him up to the majors twice during that season, in mid-May then again in late-July. He appeared in 12 games total, always as a pinch hitter and only once staying on as a defensive replacement. On May 18, he collected his first major league hit in the seventh while pinching for Charlie Hough, hitting a single with a man on first and two out before eventually scoring the winning run in a 4-3 win over the New York Mets. 12 plate appearances is all that O’Halloran ever got, with only two hits and a sacrifice fly to show for it. In 1995, O’Halloran went 3-for-19 for the Iowa Cubs, then caught on in the independent Northern League with the Duluth–Superior Dukes. He went 18-for-79 over 23 games, hitting just .228 before calling it quits.
