Abreu plays in Oakland finale, to rest Friday

OAKLAND -- MLB home run leader Jose Abreu was penciled into Wednesday's starting lineup as the designated hitter for the sixth straight game since showing ankle discomfort while running the bases last week against the Cubs.

With Abreu in the order for the series finale against the A's, he will likely be on the bench to start Friday's series opener in Houston. Manager Robin Ventura wants to take advantage of Thursday's off-day to give Abreu consecutive days to rest his ankle, which has been an issue since Spring Training.

"He's going to fight it, but I think it's probably a good time to do that for him, just to get him two days," Ventura said. "He's still limping around. You look at it and you wince, but he is getting better. It might not look like it, but he is."

After hitting a game-winning three-run homer in Wednesday's 4-2 victory, Abreu leads the league with his 15 homers, 27 extra-base hits and 103 total bases while his 41 RBIs rank second. Abreu has started every game this season except for April 17, when he entered the game as a pinch-hitter.

Carroll struggling but staying in rotation

OAKLAND -- Despite getting knocked around for his second straight start on Tuesday night, rookie right-hander Scott Carroll will remain in the White Sox rotation.

Manager Robin Ventura confirmed as much with reporters on Wednesday, though it wasn't a ringing endorsement.

"Right now, he will," Ventura said.

The 29-year-old Carroll (1-3) has given up six earned runs on 11 hits in each of his past two starts, raising his ERA from 0.68 after his first two starts to 5.24. Carroll earned his first MLB callup on April 27, the same day top pitching prospect Erik Johnson was sent down to Triple-A Charlotte after enduring his own struggles to begin the season.

Since going 1-1 with a 6.46 ERA and 1.78 WHIP in five starts with the White Sox, Johnson has made three appearances for the Knights with a 2.84 ERA and 1.00 WHIP. Ventura said the team has been keeping tabs on the 24-year-old righty, making his return to Chicago sound inevitable.

Johnson gave up four earned runs on nine hits across six innings on Monday, and Ventura said the right-hander will make at least one more start with Charlotte.

"There's not a set plan of so many starts he has to have before he comes back," Ventura said. "You start getting reports and you go from there and make an assessment and judgment based on that. We'll just continue to monitor him."

Third to first

• The White Sox had lost seven straight games in Oakland before winning Wednesday's series finale.

"This is a tough place to play," Ventura said. "These guys, they swing the bat, they play smart baseball. They have good pitching. We've seen it over the years that they're pretty good at knocking guys in. They get 'em on and do some stuff. They get a little momentum anytime someone gets on."

Adam Eaton (strained right hamstring) spent the morning with the White Sox before heading to Durham, N.C., to go on a rehab assignment with Triple-A Charlotte.

"I was watching him do stuff yesterday," Ventura said. "He was out doing stuff in the outfield, running around. His game is being able to use his legs. You don't want to keep that from him, you don't want to hamper him and have him go out there without having every possible thing he can use successfully for him and us."
