The Braves simply haven't scored many times during the last 15 games, plating two runs or fewer in eight of their last 11 losses.
The good thing is that, at least Monday with Medlen, two runs might be enough. The right-hander has a 28 1/3 scoreless innings streak and the Braves have won the last 17 games he has started -- including their most recent victory on Tuesday against the Padres.
"He's been unbelievable," second baseman Dan Uggla said. "I remember facing him and it wasn't that fun, either. He goes out there, knows what he has to do and executes. He's got that great changeup and puts his pitches where he wants to put them."
Although the Rockies aren't near the Braves in the Wild Card standings, they pose a dangerous threat nonetheless. While Atlanta has struggled, the Rockies are 14-6 in their last 20 games.
Right-hander Tyler Chatwood, who opposes Medlen on Monday, also has been impressive as of late. He's 3-2 with a 3.42 ERA since being recalled from Triple-A Colorado Springs in August, winning three of his last five outings.
Rockies: Rosario nears rookie mark
Catcher Wilin Rosario, who has a six-game hitting streak, is posting impressive power numbers during his rookie season. Rosario needs one home run to pass Geovany Soto (2008) and J.P. Arencibia (2011) for the fourth-most home runs by a rookie catcher. He's also two homers away from tying Todd Helton for Rockies' rookie record.
Troy Tulowitzki is scheduled to play seven innings Monday at shortstop for Triple-A Colorado Springs as he continues his rehab assignment. He will then be re-evaluated.
Braves: Baker happy to be with Braves
Jeff Baker wasn't sure what his future held when the Tigers designated him for assignment Friday afternoon. But when he discovered he was traded to the Braves hours before the deadline to be eligible for their postseason roster, he was relieved.
"When I found out I was coming here, I was really excited," Baker said. "A team that's leading the Wild Card, and on top of that, a class organization."
The Braves are 46-15 in games in which Michael Bourn records at least one hit and scores one run.
Chatwood tossed seven innings of one-run ball in his lone career start against the Braves on May 22 of last year.
Colorado's Jordan Pacheco has an 11-game hitting streak, during which he's batting .357.
Colorado's Tyler Colvin has a seven-game hitting streak of his own, during which he's batting .370 with three homers and 11 RBIs.
Uggla has a five-game hitting streak.
