DENVER -- Pitcher Jeff Samardzija, whose season was derailed by right shoulder inflammation that surfaced in Spring Training, said Tuesday he will continue to seek information from shoulder specialists as he plots an offseason rehabilitation program.
While surgery has been ruled out and an anti-inflammatory injection did not lead to a recovery, Samardzija, who made just 10 starts for the Giants this season, continues to do shoulder strengthening exercises but is not playing catch.
The Giants transferred Samardzija to the 60-day disabled list Tuesday to make room on the 40-man roster for newly acquired infielder Abiatal Avelino, who was promoted from Triple-A Sacramento.
Samardzija went 1-5 with a 6.25 ERA this season. He made eight starts from April 20 to May 4 and at times was able to increase his velocity as the game progressed. But after another stint on the 10-day disabled list, Samardzija made two starts on July 7 and 14, and in the latter outing, his velocity was low from the start and didn't rise.

"It's kind of let's get it better and pitch-type mode and stay ready," Samardzija said, summarizing his approach out of Spring Training. "So right now, we're kind of taking a little bit of an adjustment and just kind of ensuring we're getting as much information to make the right decision."
Samardzija, who will spend the offseason rehabilitating in San Francisco, said his intent now is "just to get more of an exact plan of action going forward. It's been a couple different things [with the shoulder]. It just hasn't been one same thing, so therefore that makes me think we need to find out what those other things were or what came first, what came second, are we treating pain or are we treating the problem?"
Samardzija, 33, has two years remaining at $18 million annually on the five-year, $90 million deal he signed with the Giants as a free agent after the 2015 season.
New arrivals
The Giants purchased the contract of Avelino from Sacramento and also recalled infielder Ryder Jones from that team. Manager Bruce Bochy said there would be no more September call-ups, and that Avelino -- acquired from the Yankees on Friday in the deal that sent right fielder Andrew McCutchen to New York -- would get some starts at shortstop but not in "important games" unless regular shortstop Brandon Crawford, who returned Monday after missing three days due to left knee soreness, needs rest.

That means Bochy is apt to start Avelino against teams not vying for the postseason. The only team on the Giants' schedule in that category is the Padres, and the teams play each other six more times this season.
Bochy said Avelino's pre-game work will be at shortstop but he could play second base as well and can come off the bench to pinch-hit or pinch-run. Avelino hit a combined .283 with a .767 OPS and 13 doubles, eight triples, 15 home runs and 27 stolen bases this season in 126 games between Double-A Trenton, Triple-A Scranton-Wilkes Barre and Sacramento.
Bochy said he spoke with Sacramento manager Dave Brundage, where Avelino played three games and received a good report.
"Stole a couple bases there," Bochy said. "Runs well, good actions at short. Really good arm. He looked comfortable there. So I have a guy I can use late in a game, pinch-run or pinch-hit. Got some pop. He's intriguing in the fact you can move him around similar to [Alen Hanson]."
Jones played one game with the Giants when they called him up in July. In 116 games with Sacramento, he hit . 274 with a .746 OPS and 22 doubles, four triples, 11 homers and 59 RBIs.
Worth noting
• Center fielder Steven Duggar underwent successful surgery Tuesday morning to have a labrum tear in his left (non-throwing) shoulder repaired. The operation was performed in the Phoenix area by Dr. Gary Waslewski.
