Sore triceps lands Ramirez on disabled list

CHICAGO -- Reliever Neil Ramirez, who was optioned to Triple-A Iowa on Saturday to give him some rest, was placed on the Major League disabled list on Tuesday because of soreness in his right triceps.

Ramirez had given up three earned runs over 28 innings in 33 games, for a 0.96 ERA, and the Cubs made clear that Saturday's demotion to the Minors was not performance-related. But Ramirez experienced some soreness, which prompted the team to switch him to the DL, retroactive to Saturday.

"All year we've talked about giving these guys some rest," general manager Jed Hoyer said on Tuesday. "You convert a bunch of starting pitchers to the bullpen, they've never done it before, and that was the intention -- to give him a rest. We've tried our hardest to be careful with him, getting him up and down, and not pitching back-to-back days."

When Ramirez was optioned, the plan had been for him to be sidelined the minimum 10 days, but now he will have 15 days to rest, and he is expected to return once the DL stint is over.

"That was probably the right way to handle it once he was sore," Hoyer said.

Manager Rick Renteria said that the Cubs may try to give other relievers some extended rest, but Hoyer hopes that isn't necessary. When rosters expand in September, the Cubs should have reinforcements.

"In general, we've seen a dip in performance with our young relievers, and they all look a little bit tired," Hoyer said. "If we can give those guys a rest, we will."

There has been no discussion about having Ramirez stretched out to start.

"He's a pretty emotional guy, and sometimes those guys fare well out of the bullpen," Hoyer said of the rookie. "You see the fist pump when he gets a big punchout. He doesn't shy away from the big at-bat."

Fujikawa nearing end of rehab stint

CHICAGO -- Kyuji Fujikawa, rehabbing from Tommy John surgery on his right elbow, will make at least one more rehab outing with Triple-A Iowa, general manager Jed Hoyer said.

Hoyer met with the Cubs' athletic trainers on Tuesday to discuss the final days of Fujikawa's rehab. Fujikawa pitched in back-to-back games on Saturday and Sunday, and has given up seven hits and walked three while striking out 12 over 9 2/3 innings in four games at Iowa.

"He's getting there, and the end of his rehab stint is coming," Hoyer said on Tuesday. "I think he can see the light at the end of the tunnel."

Fujikawa underwent the surgery in June 2013.

In other injury news, right-hander C.J. Edwards, seventh on MLB.com's list of the Cubs' Top 20 prospects, is expected to rejoin Double-A Tennessee. Edwards, who has been sidelined after experiencing some discomfort in his shoulder, gave up one run on one hit and three walks over 3 2/3 innings for the Mesa Rookie League team on Monday, striking out six.

"It's been a long season for him, and he's excited to get back out there," Hoyer said.

Edwards made four starts for Tennessee before being shut down, and gave up six earned runs over 20 2/3 innings for a 2.61 ERA.

Hoyer: Cubs may be done dealing

CHICAGO -- General manager Jed Hoyer has had plenty of conversations with other teams in advance of Thursday's non-waiver Trade Deadline (3 p.m. CT) but said that the Cubs may not make another deal.

"It wouldn't surprise me if we made no moves," Hoyer said on Tuesday. "We're having a lot of conversations. It's still early. [Wednesday] is sort of moving day. I expect things will get more serious as we move into tomorrow. People have some reluctance on the last day.

"[Wednesday] evening is when a lot of people hone in on the deals they want to make," he said.

The Cubs made their blockbuster move on July 4, trading starters Jeff Samardzija and Jason Hammel to the Athletics for four players, including highly touted shortstop Addison Russell and outfielder Billy McKinney.

Other teams are still trying to find the right match.

"People try to find a dance partner on the 30th and 31st," Hoyer said. "As you get to [Wednesday] evening, people want to make deals, and they're more willing to pair up, and I expect that to be the same thing."

Manager Rick Renteria does not feel that his players are thinking too much about the deadline.

"There are things they can't control," Renteria said. "I don't sense they're too preoccupied with it now."

Extra bases

• Javier Baez has started 11 games at second base for Triple-A Iowa, and all reports have been good, Hoyer said on Tuesday. The Cubs also like Baez's play at shortstop; Hoyer wanted to be clear that Baez is playing second not because he can't play short but to increase his versatility.

"Before we moved him to play a lot of second, our reports were really good on his shortstop play," Hoyer said. "His hands are really good, his range is surprisingly good. We definitely feel he can play shortstop."

Hoyer said that there are three players in the organization who can play shortstop in the Majors, including Baez, Russell and Starlin Castro.

• The Cubs were one of 28 teams watching Cuban outfielder Rusney Castillo work out in Miami on Saturday, sending five people to watch the speedster.

"We scouted him heavily, and beyond that I couldn't comment," Hoyer said.

The Cubs have been active in the international market, and signed Cuban outfielder Jorge Soler in June 2012.

• There is no timetable for right-hander Dan Straily to join the Cubs. Straily, acquired from the Athletics in the July 4 deal for Samardzija and Hammel, is working as a starter at Triple-A Iowa.

"He's getting himself back on track," Renteria said of Straily, who is 0-3 with a 5.85 ERA in four starts with Iowa.
