SEATTLE -- Sinking lower by the day in a slump that, with each loss brings them closer to a breakup, the White Sox suffered a double-edged blow in a 7-4 loss to the Mariners at Safeco Field on Tuesday night.
Right-hander Jake Peavy, a valuable trade chip if and when general manager Rick Hahn decides it's time to raise the white flag and deal veterans for prospects, left in the third inning against the Mariners with pain in a rib on the left side of his chest area.
X-rays were negative. Before his team attempts to halt an eight-game losing streak against the Mariners on Wednesday, Peavy will be going for an MRI.
Peavy will almost certainly miss at least one start and could be facing time on the disabled list. The discomfort began on Sunday when the team was in Oakland, it was revealed after the game, and he went to a doctor on Monday. He said he knew warming up before the game that he wasn't going to be at his best.
"Tonight obviously with every pitch it got worse,'' Peavy said. "It's something that's pretty acute, pretty sharp. I couldn't physically do much from the start of the game. Try to gut through it and it's just frustrating.''
"Early on, you could see he was throwing but it didn't seem to have the zip that you normally see,'' manager Robin Ventura said.
Peavy said it hurts taking deep breaths and that he couldn't imagine being ready to make his next start.
"Just walking I can feel it,'' he said.
If Peavy, who gave up six runs on seven hits, isn't healthy or is deemed a health risk, he of course won't be worth as much to the Sox in a deal for younger players or prospects. This was the second abbreviated outing for Peavy following two 117-pitch efforts, including a complete game victory against the Miami Marlins on May 25.
Peavy's velocity topped out at 90 mph Tuesday, about three mph below normal. After Raul Ibanez, who had homered in the first inning, followed a double by Kendrys Morales with a double of his own, manager Robin Ventura visited Peavy. Trainer Herm Schneider joined in and escorted Peavy off the mound with the Sox trailing 6-2.
Peavy threw 69 pitches in a four-inning outing against the Cubs at Wrigley Field on Thursday, when he was tagged for six runs on eight hits.
Hernandez (7-4) gave up four runs, two on Adam Dunn's 13th homer in the second and Tyler Flowers' RBI double in the eighth.
A night after bench coach Mark Parent was ejected for arguing balls and strikes, manager Robin Ventura had three visits with the umpires about an appeal play at first, a replay review of Nick Franklin's homer that was changed to a double and a beef about catcher Tyler Flowers being interfered with on an attempted steal.
"I spent too much time on the field tonight,'' he said.
Peavy gave it the old college try knowing his team desperately needed a win and because Hernandez, like him a Cy Young winner, was pitching.
"It's hard for me when it's not my arm or something else,'' he said.
"When your team is losing this many in a row, you're going against Felix, this is what you live for as a competitor to go against their best guy. I was bumming out even before the start that I wasn't going to get a good crack at it and go out there feeling normal and go out there. at the same time I felt like was willing myself to go out there and make pitches, I wasn't able to do that.
"When you fight back from arm injuries and significant injuries you feel are part of the game, to have something like this flare up and not even sure how, it's frustrating and sickening. It brings tears to my eyes.''
