James Ross Walker (born July 1, 1971) is an American former Major League Baseball relief pitcher.

He attended Austin Peay State University between 1990 and 1992 and ranks fifth all-time in school history with 17 wins and first with three career shutouts.

[1] Walker crossed the picket lines and participated in spring training during the 1994 Major League Baseball strike as a replacement player.

The record was held by Scott Aldred (a former Tiger, coincidentally), who made 48 appearances for the 1998 Tampa Bay Devil Rays while accomplishing this feat.

[5] However, Aldred's record would only hold for one more season, as Trever Miller of the Houston Astros set the new mark by making 76 appearances without a decision in 2007.
