If all goes well, the right-hander will join the Cubs in Washington D.C. for their weekend series against the Nationals.
Fujikawa has been sidelined since April 13 with a strained right forearm and pitched one inning in a rehab outing Sunday for Triple-A Iowa.
• Anthony Rizzo was batting .439 with seven doubles, three home runs and 11 RBIs in his last 11 games, and has raised his average from .173 on April 25 to .262.
"The bottom line is you just get more comfortable," Sveum said. "Coming out of Spring Training, it's totally different how pitchers will start pitching you, and you'll see a lot more breaking balls as the season goes on, which you don't see much of in Spring Training, and you see different kind of pitchers. It's just getting your at-bats and getting better pitches to hit, for one. He's still a little bit aggressive, but right now he's taking advantage of mistakes he's getting."
• Cody Ransom is the only backup infielder on the Cubs' roster, and he's been getting some extra work at first base in early batting practice. Rizzo is the regular, but the Cubs don't have a backup.
"You never know if [Ransom] will get over there one day," Sveum said. "Hopefully not. Especially the way Rizzo is swinging against left-handed pitching. It's a just-in-case thing."
• Right-handed pitcher Cory Wade, who was pitching for Triple-A Iowa, was released, the Cubs announced. In 16 innings over 10 games at Iowa, Wade gave up 14 runs on 28 hits and walked seven while striking out 16.
