"Everything has been good so far," Peralta said. "I feel no pain."
Peralta went on to explain that the discomfort that sent him back to the DL was not persistent, but rather surfaced primarily when he took a hard swing and did not make contact.
"When I hit the ball," Peralta noted, "it was fine."
Though the inflammation was not in the spot that was surgically repaired in March, Peralta said he was told by the medical staff that the issue does often present itself while someone is regaining strength after that sort of surgery. The strengthening process continues, and it remains to be seen whether Peralta's production is limited at all because of that once he returns.
In the 30 games Peralta played before his second DL stint, he went 25-for-113 (.221) with seven doubles and five homers. His slugging percentage (.416) was actually higher than the mark he had in 2015.
"I'm coming back and hope to do the best I can," Peralta said. "I'm staying positive."
The role that awaits Peralta remains fuzzy, too. Since July 18, the date Peralta was moved to the DL, Jedd Gyorko has hit .310/.370/.810 with a 1.179 OPS, seven homers and 11 RBIs. With that production, Gyorko has positioned himself for continued consideration at third base even when Peralta returns to the mix.
"We'll just wait and see when we get there," manager Mike Matheny said. "We'll figure out how it all comes together and how we plug them in once we get there."
• Stephen Piscotty remained out of the lineup for a second straight day, and Aledmys Diaz joined him on Saturday as Matheny felt both players needed a breather. Piscotty stepped away entirely on Friday -- "a good shutdown day," Matheny described it -- and then went back to work in the batting cages on Saturday. He is hitless in 12 at-bats on the road trip and has struck out eight times.
Diaz had started nine straight games, including both ends of Tuesday's doubleheader in New York. He is on call to return home to nearby to West Palm Beach, Fla., for the birth of his first child, though Matheny said the decision to hold the rookie shortstop out of Saturday's lineup was unrelated to the personal matter.
• Brandon Moss (left ankle sprain) went 0-for-2 with a walk while playing seven innings for Double-A Springfield on Friday. It was Moss' second appearance since beginning a rehab assignment.
