"He still has some reoccurring headaches," Black said. "I think it's doubtful that he's coming off the [disabled] list once the 15 days are up. We're just hoping he continues to improve and is eligible to play come September."
Barrett was put on the 15-day DL on Aug. 11 with concussion-like symptoms after being hit on the head by Reds shortstop Alex Gonzalez's shin. It was the second blow to the head Barrett received in a six-day period.
"As of now, he's getting better each day," Black said. "First of all, we got to get him healthy and stay that way.
"I'm not familiar with, obviously, concussion-type symptoms. These are just concerning through a personal side, let alone a baseball side."
Barrett received his first blow to the head as a foul ball hit his face mask on Aug. 5 when the Padres were playing against the Giants.
While he's unable to play, Barrett is spending time in the bullpen with the relievers, who have been keeping him company.
Barrett is one of the new faces in the Padres clubhouse this summer. He was acquired from the Cubs on June 20. Barrett is hitting .248 with 29 runs, 37 RBIs and nine home runs for the season.
Sense of urgency: The Padres have 40 games to go before the regular season ends. And with two straight losses to the visiting Astros, some are wondering if they are feeling antsy or even distressed about their current situation. San Diego is five games behind the Diamondbacks in the National League West standings. While they sit in second place in the division, the Padres also are tied for the lead in the NL Wild Card race.
"I think, well, there's still a quarter of a season left," Black said. "What lies ahead of us is for us to play good baseball. At this point, we still determine our own fate. There's still 40 games left on the schedule.
"This is a time where ... you can't afford to not play good baseball. And with that said, part of our strength for the first three quarters of the season has been our overall consistency of play."
Sure, the Padres were consistent in the beginning, but now they are turning streaky again on offense. They pulled out their first three-game series this week by scoring nine runs in the fifth inning in the rubber match to top the Rockies, 11-9. But now San Diego has dropped two in a row against Houston.
"We haven't lost four games in a row. We've shown great resiliency after a tough loss to bounce back and win," Black said. "We have shown a resolve during the first third of the season that will remain intact as we go forward through these last 40 games.
"Like I said last night, out goal is to win today and go to New York and win Tuesday and win way more often than we lose. And if that occurs, then I like our chances."
Peavy gone after 2009? Padres ace Jake Peavy told the San Diego Union-Tribune he may not be with the club after the 2009 season due to a franchise that seems unwilling to pay big money for one player. Peavy even told the newspaper the team may trade him before the expiration of his four-year contract is complete.
"I hope it's not the case, but I think it's inevitable that I'll wind up somewhere else. I am not looking to break the bank. I'm not saying I want a huge payday. I'm going to ask for what's fair. And although I hope it happens here, I just don't see the Padres spending that much on a player," Peavy told the San Diego Union-Tribune.
Peavy always is one to wear his emotions on his sleeve, including telling the newspaper he wasn't sure if the franchise really was making the right moves to try to win a World Series.
"I'm more concerned about the team making a conscious effort to win a world championship," Peavy told the newspaper. "At times I don't know if they've gone out on a limb to make it happen. I believe the big philosophy is right. But the first question I'd ask is, 'Can you give me your word that we're going to make an effort to win the World Series?'"
Peavy's four-year contract guarantees him $15 million, including $4.5 million this season, according to the UT.
Bradley close to ready: Left fielder Milton Bradley most likely will be in the lineup on Tuesday when the Padres open a three-game series against the Mets.
"Milton, he'll be ready to go Tuesday -- that's our tentative plan," Black said. "He'll be available today if the situation arises to pinch-hit. He's feeling much better, more confident in the hamstring and now it's coming along. He's really close."
Bradley strained his right hamstring on Aug. 2 against the Diamondbacks. He has played in only two games since his injury.
On deck: The Padres start their first contest of a three-game series against the Mets at Shea Stadium on Tuesday at 4:10 p.m. PT. Chris Young (9-4, 1.93 ERA) will get the start for San Diego. New York will counter with John Maine (13-7, 3.59 ERA).
