Matt Thornton admits he initially wasn’t as confident his elbow was fine, but those concerns have since been alleviated.

The White Sox reliever threw 40 pitches on Wednesday in batting practice and believes he hasn’t lost any ground.

Thornton missed several days last week and required an MRI, which showed no structural damage, because of inflammation in his throwing elbow. But he is set to pitch again Saturday in the bullpen and will appear in a White Sox game on March 5.

“I didn’t know what it was at the time,” Thornton said. “I knew it was sore. I cranked it up a little too much too early knowing I had time and all that. So it kind of went the wrong way this time. We backed off a couple days, picked it right back up and didn’t lose anything I worked for this offseason.”

Thornton said he didn’t have to hold back during Wednesday’s session and threw all of his pitches.

“No problems at all,” Thornton said. “I let everything go. I threw everything I had and as I went along I amped up the intensity and let ‘em go.”

Konerko, Gillaspie hit first homers

Paul Konerko needed only seven at-bats to hit his first home run of the spring when he clubbed a two-run shot Wednesday in an 8-4 win over the Texas Rangers. Manager Robin Ventura said the early homer should help Konerko eliminate any pressure he might place on himself.
