All but one of Zobrist's at-bats before the injury came in the third spot in the order, and he started five games at second base and seven in the outfield. He is batting .240 with a home run and eight RBIs.
Zobrist left in the fifth inning of the April 19 game in Kansas City with knee soreness, was placed on the DL on April 25 after trying to play through the injury and underwent successful surgery on April 28. He was expected to miss between four and six weeks, but he appears to be ahead of schedule.
"It's impressive he's recovered so quickly," Melvin said.
In related news, first baseman Ike Davis (strained left quad) will miss at least a few more days. He left Monday's game in the fourth inning.
"He's still feeling it a little bit," Melvin said. "With the off-day and facing three left-handers in a row, we can give him some time to get over it. We knew it would be a few days anyway."
