On Wednesday, pitcher Randy Wells was designated for assignment, and right-handed pitcher Rafael Dolis was recalled from Triple-A Iowa. Wells did have options left, but by designating him, he was removed from the Cubs' 40-man roster, which is now at 39.
On June 11, there were reports the Cubs had won the bidding for Soler, and the outfielder had agreed to a nine-year, $30 million contract. The Cubs have declined to confirm the signing.
Soler, 20, was declared a free agent in early June and was courted by several teams. The Cubs and Soler need to complete the deal before Tuesday, or else they will be subjected to the new Basic Agreement guidelines, which will limit spending on international prospects to $2.9 million per team without penalty.
When asked about Soler on Tuesday, Cubs general manager Jed Hoyer said he had no update.
A power-hitting right-handed hitter, Soler played for the Cuban national team in the 2010 World Junior Baseball Championship, batting .304 with a .500 on-base percentage and .522 slugging percentage. He defected in 2011.
Wells was 1-2 with a 5.34 ERA in 12 Major League games, including four starts, and 2-2 with a 7.71 ERA in six starts with Iowa. He struggled on Tuesday against the Mets, giving up three runs on six hits and four walks over three-plus innings.
"The command and the walks are still a major issue," Cubs manager Dale Sveum said. "He's got to get better at that. Those things are killing him and the pitch count gets up so high, he can't even get to five innings. He's got to go down and get better at that."
Wells could go back to Iowa if he is not claimed by another team.
Dolis began the season on the Cubs' Opening Day roster, and posted a 2.79 ERA in his first 16 outings. He replaced Carlos Marmol as the closer, but then struggled in his last seven games, giving up 10 earned runs over six innings. He was optioned to Iowa on May 28. In 11 relief appearances in Iowa, he compiled a 2.92 ERA, striking out 13 over 12 1/3 innings.
