LOS ANGELES — Thursday's trading deadline passed, but the Cubs are far from done in trying to improve in the final two months of another losing season.
A starting rotation that changed by 40 percent following the trade of ace Jeff Samardzija and Jason Hammel is bound for more change in the next month, depending on the health of newly-acquired left-hander Felix Doubront and perhaps the struggles of Edwin Jackson.
Doubront, 26, is very excited about joining the Cubs as soon as he recovers from a calf injury and rebuilds his pitch count after being pulled from the Red Sox's rotation in late June.
"I'm going to start a new journey right here," said Doubront, who was traded after a 2-4 record and 6.07 ERA in 17 games with the Red Sox. "And I'm happy to be here and excited to join the team."
Kyle Hendricks continued his audition Friday night and was aided by Luis Valbuena's home run as the Cubs and Dodgers were tied 1-1 early.
Left-hander Tsuyoshi Wada, 33, will try to keep his spot in the rotation for the rest of the season as he starts Saturday night.
With the departures of Samardzija and Hammel to the Athletics, Jake Arrieta has cemented his spot at No. 1 in the rotation with left-hander Travis Wood trying to balance an uneven season.
That leaves Jackson, who has a 5.79 ERA in 22 starts with opponents batting .293 against him, under some pressure. The Cubs owe Jackson, 30, about $25 million on the balance of his contract that runs through 2016.
They could give him a break in September if he doesn't pitch well and take a look at other candidates, although that has yet to be mentioned publicly.
Meanwhile, Doubront was invigorated to be reunited with President Theo Epstein from their days with the Red Sox, and Doubront emphasized he didn't request a trade from the Red Sox.
Doubront will report to the Cubs' spring training facility in Mesa, Ariz., next week and then make a couple of minor league rehab starts before joining the Cubs.
"I would like to be a part of this building process," said Doubront, who is 26-22 over five seasons. "And if they give me a chance to be around here, it's going to be a competitive team."
The rest of the roster remains somewhat in flux as general manager Jed Hoyer said the Cubs will examine the waiver wire as they did last August when outfielder David DeJesus was claimed and traded to the Nationals.
Outfielder Nate Schierholtz, who is batting .197 after hitting 21 home runs last season, is aware of the changing landscape.
"I'm past the point where I'm trying to make up for the past and looking for the future," Schierholtz said. "I'm going to treat every day as a new day and get back to producing.
"I'm aware of what can happen. But I'm just trying to play my best and the better I play, obviously the better things will turn out for everyone."
