White Sox riding wave of ups and downs

BALTIMORE -- Since Aug. 14, it's been a tale of streaks for the White Sox.

Chicago won three straight over the Blue Jays, lost three straight to the Royals and took six straight from the Yankees and Mariners. A trip to Baltimore has brought consecutive losses to the Orioles heading into Wednesday's game, but manager Robin Ventura didn't attach to0 much significance to that roller-coaster ride.

"It's who you play, when you catch them, how their guys are feeling," Ventura said. "There's a lot of different things that go into it that you can't ever foresee. For me, it's more about our effort and how we prepare and go into it. The wins and losses are going to be what they are, but guys focusing and being ready every day is all you can ask."

The White Sox have also won their past seven home games and dropped five straight road contests.

Ventura isn't concerned, partly because he doesn't see a problem falling on certain pitchers.

"It would be one thing if it were a definite reason why," Ventura said. "It's just part of playing the game and having a long season."

Struggling Pierzynski sits against Orioles

BALTIMORE -- White Sox catcher A.J. Pierzynski has gone hitless in his last 14 at-bats and is 5-for-32 (.156) over his past 10 games prior to Wednesday against the Orioles.

The veteran backstop wasn't in the lineup for the second time in four games on Wednesday, with backup Tyler Flowers getting the nod instead.

Despite those recent struggles, manager Robin Ventura didn't go so far as to say Pierzynski is dealing with a slump.

"I don't know if it's that," Ventura said before Wednesday's game. "I mean, he can get frustrated just like anybody else. I'm just trying to give him a break here or there.

"I think it's more for the mind than anything else. Tyler's been doing fine lately, so it's a good break for A.J."

Flowers entered Wednesday hitting .423 (11-for-26) with four home runs this month. Still, Ventura said Pierzynski would return to the lineup for Thursday afternoon's series finale.

Overall, Pierzynski is hitting .288 with an .861 OPS and a career-high 23 home runs. Ventura doesn't see anything amiss with the 35-year-old's swing.

"You can do a little bit of pitch selection, things like that," Ventura said. "But mechanically he's doing the same things. He's got great hands, probably just swinging at pitches he wishes he didn't."

The White Sox will likely will have to call up another catcher from the Minor Leagues before Thursday's game, with Flowers a candidate for paternity leave, with his wife expecting their first child.

Chicago has used only Pierzynski and Flowers behind the plate this season and doesn't have another backstop on its 40-man roster. Damaso Espino, Hector Gimenez and Josh Phegley are the current catchers at Triple-A Charlotte.

Injuries won't prevent Peavy, Ramirez from playing

BALTIMORE -- White Sox pitcher Jake Peavy and shortstop Alexei Ramirez are not expected to miss any action while recovering from minor injuries.

Peavy's next start had already been pushed back from Wednesday to Friday before he developed a right eye infection, similar to one he had during Spring Training. The right-hander left the park early on Tuesday for treatment, but was back on Wednesday and remains on target to pitch Chicago's series opener at Detroit on Friday.

"He looks better," manager Robin Ventura said before Wednesday's game. "There's still a little something there, but he wasn't wearing glasses today, which I took as a good sign. They're not very attractive."

Ramirez suffered an injury to the nail on his right pinkie finger while going for a barehanded pickup on Monday. He started on Tuesday and went 0-for-1 with two walks before he was replaced by Ray Olmedo before the bottom of the seventh inning.

Ramirez was in the lineup again on Wednesday, playing shortstop and batting seventh.

"He's fine," Ventura said. "I think it's one of those things, it's going to be time for it to totally heal, but it's a little sore. Last night, just tried to give him the last couple of innings off, just to get it treated."

Worth noting

• The White Sox are hitting .174 with 11 runs scored in their five straight road losses.

• Pitchers Andre Rienzo, Santos Rodriguez and Taylor Thompson, infielders Carlos Sanchez and Andy Wilkens and outfielder Trayce Thompson will represent the White Sox in the Arizona Fall League, playing for the Salt River Rafters.
