With Barrett feeling 100 percent healthy and ready to go after doing a three-day rehab assignment with Triple-A Portland this week, the veteran catcher will be activated from the disabled list Saturday when the rosters expand from 25 to 40 players.
Barrett has been on the disabled list since Aug. 11 with concussion-like symptoms after receiving two blows to the head in the span of a week.
"My concentration level is back up to 100 percent, which is important," Barrett said. "It's important to understand that there was a time it wasn't and now that it's back to where it is, now I can play. I know I'm good to go.
"At least now I know I'm 100 percent when I go out there. If something happens, it was a lack of concentration; it wasn't because post-concussion syndrome or it was a mental mistake, it wasn't because of a mental injury. That's one good thing I feel good about. Just getting back in the flow of the game and looking in, getting the signs."
Barrett said that while he felt well enough 10 days ago, he still felt the need for a rehab assignment.
"For me, my body felt great but I had to test some of those things out without hurting the team," Barrett said. "I didn't feel like I could take a chance. My conditions, I couldn't just go into the game and not know how I felt, and all of a sudden you have the bases loaded and I forget like how many outs there are or something.
"It's important to have gotten that under my belt and to have that confidence now to come back and say, 'Look, now that we get in these crucial games, I know where I'm at, I know that I'm locked in and I know I wont have any difficulty concentrating.' And I think it helps the entire team feel good about where I'm at."
Barrett was with the Beavers from Tuesday-Thursday, for three of their games against Triple-A Tucson. He was able to see plenty of time crouched behind the plate and at it, collecting two hits in 11 at-bats.
Barrett has played in 31 games for the Padres and is hitting .231 with eight RBIs. Barrett would like to improve on those statistics over the final month of the regular season.
"I haven't really swung the bat like I feel like I'm capable of since I've been here," Barrett said. "But I'm still working on that, and that's another good thing. I got a chance to go down and iron some things on my swing and work on some things that I think will help me be a more productive player here."
Bringing it back: Lost in the 8-7 defeat to the Diamondbacks on Thursday was the highlight-reel play turned in by Padres third baseman Kevin Kouzmanoff on a foul ball in the first inning.
With two outs, Padres pitcher Chris Young got Eric Byrnes to hit a high popup that appeared to be drifting into the seats down the third-base line, just past the visitors' dugout.
Actually, it did just that. Only Kouzmanoff dove into the stands headfirst -- note, he did not reach into the stands --- only to emerge with the ball.
"I didn't feel anyone trying to help me up," Kouzmanoff said, smiling. "I felt some pats on my back. I was just really set on catching the ball."
Kouzmanoff didn't just bolt from his position for the ball, though. He had a plan in mind.
"I think first, you have to run over there, find the wall and see where you're at and make small adjustments from there," he said. "I have never done that before."
Aside from seeing the replay on the PETCO Park scoreboard after the game, Kouzmanoff still hasn't watched a television replay of the catch that was highlighted on ESPN.
Roster roulette: As expected Friday, the Padres recalled pitcher Jack Cassel from Triple-A Portland in time to start against the Dodgers.
The Padres designated catcher Pete Laforest for assignment, requesting waivers on him to make room on the 40-man roster.
There were two other moves made that certainly won't effect the 25-man roster anytime soon, though they could impact the flexibility of the team's postseason roster.
The Padres reinstated infielder Oscar Robles and left-handed pitcher Ryan Ketchner from the Portland disabled list, recalled them and then subsequently placed them on the Major League disabled list.
The Robles and Ketchner moves would allow the Padres to move anyone on their 40-man roster or any contract that they would purchase between now and the end of the season to their postseason roster for those spots.
The Padres will recall two players on Saturday from Portland when the 25-man roster expands to 40 players -- outfielder Brady Clark and first baseman Brian Myrow.
Manager Bud Black indicated that several more players would be recalled Tuesday after the Beavers' season has ended.
Normal soreness: Black said Friday that Young was experiencing the normal "day-after soreness in the arm" and in his back after Young threw 4 1/3 innings against the Diamondbacks.
Black said Young is on target to make his next start on Tuesday in Arizona, and that he doesn't see the tightness in the lower back that caused Young to miss one start being an issue moving forward.
"I thought yesterday he threw the ball, stuff-wise, good," Black said. "Obviously, he was erratic in the zone and outside the zone. But he was rusty and his mechanics got out of whack."
Young walked six in his start, allowing five runs on two hits, though he was gone from the game when four of those runs crossed the plate.
On deck: The Padres continue their three-game series with the Dodgers at 7:05 p.m. PT on Saturday at PETCO Park. Jake Peavy (15-5, 2.18 ERA) gets the start for San Diego. Derek Lowe (11-11, 3.56 ERA) will start for the Dodgers. The series concludes on Sunday.
