For about two weeks, the Marlins rotation has struggled to work deep into games.
In need of some help, the organization decided to dip into its Minor League system.
While Andrew Heaney is considered Miami's top pitching prospect, Anthony DeSclafani is also very highly regarded. In fact, it was DeSclafani who got the first callup.
On May 14, DeSclafani -- who will make his third career Major League start Tuesday night against Cubs right-hander Jeff Samardzija -- was promoted from Double-A Jacksonville to fill the rotation spot of Jose Fernandez, who will miss the rest of the season due to Tommy John surgery.
Making his MLB debut at Dodger Stadium, DeSclafani beat Los Angeles. In his next start, though, he lost to the Phillies and was later optioned to Triple-A New Orleans, where he made four starts.
Now, the right-hander is back in the rotation, taking the spot of Jacob Turner, who was moved to the bullpen. Miami is in the thick of the National League East race, and is hoping its young prospects can provide a boost.
"We're trying to win," president of baseball operations Michael Hill said. "They're a part of what we're trying to do here."
Heaney is taking the rotation spot of Randy Wolf, who was designated for assignment on Monday.
"Wolf is a pro," Hill said. "We thank him for his time in the organization, but Andrew Heaney is part of our immediate future and many years to come. We wanted to get him and DeSclafani here in the thick of this race, and help this ballclub."
Meanwhile, the Cubs will look to provide Samardzija with run support. The right-hander's last start Thursday against the Pirates was the fifth time this season he's started a game in which the Cubs have been shut out. The Cubs went 0-for-8 with runners in scoring position in the 4-0 loss.
"That's obviously not what you want to happen," Cubs manager Rick Renteria said of the lack of offense. "It's kind of a coincidence [it's happened] when Jeff's throwing."
The Cubs won their first road series of the season against the Phillies last weekend, and they'll look to clinch their second straight on Tuesday.
Cubs: Valbuena gets time as leadoff man
For the third time this season and the second straight game Monday, Luis Valbuena led off for the Cubs in place of the injured Emilio Bonifacio (right oblique strain).
Valbuena went 2-for-4 with a run scored and two walks in the Cubs' 5-4 extra-innings win over the Marlins.
Marlins: Furcal gets day off to rest knee
Rafael Furcal was given a breather on Monday night after the veteran second baseman took a foul ball off his left knee on Sunday.
Furcal finished the at-bat, singling to start the game-winning rally, but was lifted for a pinch-runner because he was noticeably injured. Ed Lucas replaced Furcal and scored the winning run in Miami's 3-2 victory.
Furcal opened the season on the DL with a left hamstring injury, and he also sustained a right groin injury.
As a precaution, Furcal was given Monday off.
"I figured no sense in pushing him out there with what he's already gone through this year," Miami manager Mike Redmond said. "... I figured, give him the day off today, and he will play the next two days."
• Marlins third baseman Casey McGehee is riding an 11-game hitting streak, which matches his career high.
• Marlins right fielder Giancarlo Stanton now has 19 homers before the All-Star break. He also reached 19 before the break in 2012.
