"It's part of what we had laid out, to also take advantage of the off-day tomorrow, to give him two days down," said Farrell. "That's what this is today."
Since seeing his 27-game hitting streak come to an end, Ortiz has seen his average drop from .414 to .333.
"He might have been pulling off the ball more than when he first rejoined us," Farrell said. "There's nothing abnormal here. We'd love to think he's going to hit .500 for the whole year, but that's probably going to tail off at some point.
"When he was in that good stretch when he first started, he was driving balls to straightaway left and left-center, which he got back to yesterday with the base hit to left. He's squared some balls up that haven't found a hole or carried, as they had when he first rejoined us. I can't say there's any one major issue he's dealing with mechanically."
With Ortiz out, Mike Napoli got a rare day to rest his legs while taking over at designated hitter and homered in the 12-4 loss. Mike Carp got the start at first base.
