PHOENIX -- James Shields threw what he deemed a very successful bullpen session prior to Wednesday's series finale at Chase Field, and he plans to throw another one Friday in Chicago.
"It went really well. Threw 30 pitches. All my pitches. With some good effort," Shields said. "Tentatively, I'm going to do almost like a three-inning bullpen [session] on Monday. That's kind of how far I've gotten right now.
"Right now, we will act like this is Day 1 and throw a bullpen [session] on Friday and do a game situation style on Monday. But everything feels really good. No pain, and I feel really strong and the ball is coming out good."
The White Sox placed Shields on the disabled list retroactive to April 18 with a right lat strain, and the right-hander had a setback that slowed the rehab process down at the start of May when the team was in Kansas City. But that trouble truly felt like history to Shields on Wednesday, who wore a wrap on his right arm and both knees after the session.

"I figured I would wrap my whole body after this one. Maybe recover quicker or something," said a smiling Shields. "I can't feel anything [pain-wise] right now.
"Just trying to build up arm strength as quickly as possible. Surprisingly, it's back a little bit quicker than I thought. It's actually coming out pretty good."
Sanchez covering new ground
Yolmer Sanchez didn't have to wait long to see action during his right-field appearance against the D-backs in the sixth inning of a 5-4 loss Tuesday. In fact, Sanchez, a second baseman making his MLB outfield debut, was the recipient of a Jake Lamb first-pitch line drive.
"A little bit nervous for the first time, but I was good," Sanchez said. "Just one fly ball."

Sanchez entered right field as part of a double-switch bringing David Holmberg to the mound. He takes fly balls in the outfield during pregame work and was ready for the challenge in the National League ballpark.
"Everything I can do to help the team, I'm going to be there," Sanchez said. "It was fun. It doesn't matter if it's in the infield or outfield. I'm going to be there."
When Sanchez caught the Lamb drive, he could be seen on the White Sox television broadcast celebrating the grab. He also received strong reviews from his teammates.
"'You look great out there,'" said Sanchez of his teammates' words of praise. "I look small because the infield is small, but I look good."
