Rodriguez missed his sixth straight game with a sprained left thumb. He said he had a good pregame workout, which included batting practice on the field for the first time since sitting out.
"This is probably the most conservative approach we've taken. I think we realize the next two months are the most important ones," Rodriguez said. "Once we see the green light, we just don't want to come back and have any more setbacks. But without a question the last two days have been very positive, no setbacks."
Rodriguez, who missed more than a month after having right knee surgery, thinks this extra time could be positive, too.
"This may be a blessing in disguise because my knee gets to be really healthy," said the 14-time All-Star third baseman.
Teixeira was hit on the side of his right knee by a pitch in the sixth inning of Thursday's game at Boston. The first baseman left an inning later when the knee stiffened up.
"He's still sore. I don't know if we'll have him [Saturday]," manager Joe Girardi said. "Maybe by the end of the weekend, it's possible."
