"I want to have a chance to see him play against lefties just in case I have to [play him against lefties in the future]," Gonzalez said. "And [Matt Diaz] is swinging it good right now against left-handed pitching."
With the Astros starting left-hander J.A. Happ on Monday, Gonzalez wanted Diaz's bat in the lineup. The veteran outfielder entered the game with eight hits, including two doubles and a homer, in 15 career at-bats against Happ.
Like Heyward, Francisco had never previously faced Happ. But when Jones returns from the disabled list, Francisco's role will become limited.
While most of Francisco's pinch-hit at-bats will come against right-handers, Gonzalez wanted to gain a better idea of how well the left-handed-hitting third baseman would fare against lefties if pressed into a more regular role.
