Prospect Berrios may not miss a start

KANSAS CITY -- Top pitching prospect Jose Berrios left his start Tuesday night with shoulder tightness, according to Twins director of Minor League operations Brad Steil, but the early reports are that it was for precautionary reasons and that he could make his next start.

Berrios, ranked as the No. 38 overall prospect and Minnesota's No. 5 prospect by MLB.com, exited his outing with Double-A New Britain after just 1 2/3 innings Tuesday.

The right-hander gave up three runs on four hits and two walks to get the loss in his fourth start at Double-A. The 20-year-old has a 4.58 ERA with 13 strikeouts and six walks in 19 2/3 innings at New Britain.

He was promoted from Class A Advanced Fort Myers in early July after posting a 1.96 ERA to go along with 109 strikeouts and 23 walks over 96 1/3 innings in 16 starts with the Miracle.

Arcia back with team after birth of son

KANSAS CITY -- Outfielder Oswaldo Arcia rejoined the Twins on Wednesday after missing Tuesday's game due to the birth of his son, Oswell Daniel, who was born early Tuesday morning.

But Arcia wasn't in the lineup against left-hander Danny Duffy, as Sam Fuld got the start in left and Chris Parmelee got the nod in right field.

"He's a very happy papa but we wanted to give him time to regroup and gather himself here," Twins manager Ron Gardenhire said. "He's gone through a lot lately. Plus, it's a pretty tough lefty [Danny Duffy] out there."

Arcia said everything went fine with his wife, Karla, and the baby, which weighed in at more than 7 pounds. He said he was happy to be back.

"I saw the lineup and I wasn't in it but I'm ready," Arcia said.

Worth noting

• First baseman Joe Mauer progressed to taking batting practice in the cages on Wednesday without any issues, according to assistant general manager Rob Antony. Mauer, who has been on the 15-day disabled list with a strained right oblique since July 2, is scheduled to take batting practice again Thursday and is expected to start a rehab assignment soon.

• Twins right-hander Mike Pelfrey began his throwing program at Target Field on Wednesday, Antony said. Pelfrey, who underwent elbow surgery in early June and is on the 60-day disabled list, remains unlikely to return this season.
