Blum and Allen batted sixth and seventh in the D-backs batting order, respectively. Manager Kirk Gibson is hoping that their presence in the lineup will help spur the offense, which has stagnated in recent games.
Blum, 38, is making his season debut after sitting out the first half of the season with a serious knee ailment that culminated in surgery. Allen, on the other hand, is up with the big club after impressing management with his statistics at Triple A-Reno during the first half.
