Rodon placed on DL; out for rest of 2017

CHICAGO -- Carlos Rodon will not pitch again for the White Sox during the 2017 season, with the southpaw being placed on the disabled list as announced by the team prior to Friday's 9-2 loss to the Giants.

An MRI on Friday afternoon showed left shoulder inflammation for Rodon, and the plan is for him to be re-evaluated next week. He was scratched with left shoulder tightness 25 minutes before his scheduled start on Thursday against the Indians.

"We'll see. Still evaluating," Rodon said. "I'll definitely be back to pitch next year, no doubt about that. Just try to get healthy and figure out the problem."

"We're just being extremely cautious," White Sox manager Rick Renteria said. "[Rodon is] a very important piece for us moving forward. We'll just see how it continues to progress as he settles into some downtime right now."

Rodon, 24, posted a 4.15 ERA over 12 starts this season, with 76 strikeouts in 69 1/3 innings. He had a 3.00 ERA over his last seven outings, with 45 strikeouts in 45 innings.

Rodon's first start in 2017 didn't come until June 28 after he missed the first three months of the season due to biceps bursitis. The southpaw didn't feel right on Thursday when he started warming up, and he said this most recent MRI showed the same results as one done at the end of Spring Training.

"For the future of the team and my future, I think it's the best thing, the best way to go about it," Rodon said. "I mean it's tough news to take, but there's not much I can do about it.

"Had some good starts, had a good run. Would've been nice to keep going, but these things happen and just got to get better."

Mike Pelfrey picked up the slack on Thursday with Rodon scratched, throwing 96 pitches. Between the emergency start and Tuesday's 2 2/3 scoreless innings of relief, Pelfrey has thrown 136 pitches.

That usage, along with an extended outing by Chris Beck and catcher Rob Brantly being forced to throwing an inning on Thursday, led to right-handed hurlers Chris Volstad and Al Alburquerque having their contracts purchased by the White Sox from Triple-A Charlotte on Friday. The moves raised the active roster total to 30 and the 40-man roster to 40.

Alburquerque, 31, combined to go 2-1 with a 2.87 ERA in 37 2/3 innings, with 43 strikeouts over 32 relief appearances in Triple-A this season. He needed one pitch to record the final out in the top of the ninth in his White Sox debut Friday.

Volstad, 30, went 3-10 with a 5.57 ERA in 27 appearances (18 starts) for Charlotte this season, his second in the White Sox system. He has not pitched in a big league game since June 24, 2015, when he was with the Pirates.

"We can use him in any number of ways," Renteria said of Volstad, adding that Alburquerque's big league experience also provides the White Sox bullpen depth over the final three weeks. "He's going to give us some flexibility. We'll deal with him as we need to, and I'm sure he's happy to be here and wants to contribute in any way he can."
