CHICAGO -- Lefty Mike Montgomery and righty Trevor Cahill are the Cubs' options to start the first game of a day-night doubleheader on Tuesday against the Brewers. Montgomery, who made back-to-back starts July 10 and 17 for the Mariners before he was acquired by Chicago, threw 42 pitches in two innings of relief on Thursday night and got the win over the Cardinals.
Cahill, who had been on the disabled list because of patellar tendinitis in his right knee, did arrive at the Cubs' clubhouse on Friday, but he was not activated. He had made six starts at Triple-A Iowa, which opens a series at Fresno on Friday.
The right-hander was in the D-backs' rotation to open the 2015 season, and he made three starts before he was moved to the bullpen.
Jason Hammel most likely will start the night game Tuesday for Chicago.
• The Cubs went 3-for-18 with runners in scoring position on Thursday, stranding 12. Their defense and baserunning have been stellar, but if there's one thing manager Joe Maddon would like to see improve, it's situational hitting.
"Situational hitting -- runner on third, less than two outs, moving the baseball when it needs to be put in play -- that's still the thing I'd like to see better, and I know they'd like to see better also," Maddon said.
"We had plenty of opportunities last night, and so did [the Cardinals]. It's an industry-wide disease. A lot of teams bemoan the fact that they're really not good with a runner on third and less than two outs. But we're young, and the fact that our guys are cognizant of that is a good thing."
The Cubs rank ninth in the National League in batting average with runners in scoring position, hitting .248.
• Chicago was sad to see St. Louis outfielder Matt Holliday sustain a fractured right thumb after he was hit by a pitch. Maddon said it was an "an absolute accident." The Cubs and Cardinals have had their disagreements in the past, but Maddon did not expect any retaliation.

"It depends on your philosophy and how you've been raised and what you think is the right way to do things," Maddon said. "It really comes down to parenting."
• Next week will be American Legion week for the Chicago players, who will rekindle their childhood days by just showing up at the ballpark and playing.
That's about as crazy as it will get for the Cubs, who have not called upon any magicians or exotic animals or reggae bands to liven things up.
"I've been pretty boring lately," said Maddon, who has his own routine of rest, bike riding and watching episodes of "The Office."
"I really do try to stay out of the way. I've always felt I can only screw them up by talking too much."
