Dave Parker, 40, cut by the California Angels last week, signed yesterday with the Toronto Blue Jays for the final three weeks of the season.
Parker will not be eligible for the postseason if the American League East-leading Blue Jays make it that far.
Parker was batting .232 with 11 home runs and 56 RBI in 119 games for the Angels, who got him from the Milwaukee Brewers in a trade during spring training.
On Wednesday, Blue Jays general manager Pat Gillick said he wasn't interested in Parker.
"We decided: 'Why not?' " Gillick said. "He's intimidating and with him sitting on the bench, the manager on the other side may change his pitching strategy."
