CHICAGO -- Ian Happ was able to celebrate his first two-homer game with the Cubs' Minor League hitting coordinator, Andy Haines, who is with the big league team for a few days. It's not that the rookie isn't working well with Cubs hitting coaches John Mallee and Eric Hinske, but Haines has been with Happ since he joined the organization in 2015.
"[Mallee] has been awesome, Hinske has been awesome," Happ said Monday. "[Haines] is really knowledgeable, a hard-working guy. I love being around him and the knowledge he brings."
Happ had been scuffling before his two-homer game against the Cardinals, in which he drove in a career-high four runs. He and Haines have been working together the past few days.
"Haines has been on my swing for two years now, and I've been with Mallee and Hinske since Spring Training," said Happ, the Cubs' No. 2 prospect. "I've only had the opportunity to spend three, four weeks with them and we're still learning each other. They're seeing my swing every day for the first time. Haines has been watching my swing for a while. I'm sure when he's watching my games on TV, he's picking stuff up but he's in Memphis or wherever."
• On Sunday night, Kyle Schwarber drew three walks, which made manager Joe Maddon happy.
"I know the grand slam [on Saturday] was wonderful, but yesterday's game was even better [because of] the fact he was not outside of his zone," Maddon said of Schwarber, who also has been scuffling.
Schwarber batted ninth on Monday for the third straight game. Maddon had inserted him seventh on Friday but didn't like it, and took responsibility. The manager also said he wasn't challenged by his coaching staff about his decision.
"When it's your baby, you react to that child much differently," Maddon said. "You have to clean the dirty diaper. There's an entire difference between me holding your baby or me holding my own. Me hitting [Schwarber] seventh was my baby, and they're not going to feel what I felt during the course of the game, but man, did I screw that up.
"I think parenthood plays a lot into whether you hit somebody seventh or ninth. Even grandparenthood has something to do with that."
• At 42 years and 62 days, Koji Uehara became the oldest pitcher to record a save since LaTroy Hawkins (42 years and 227 days) did so on Aug. 5, 2015, for the Blue Jays against the Twins.
"Koji, as long as we don't run him into the ground, he'll pitch like that all year," Maddon said of the right-hander. "You're seeing 86, 87 [mph] swung and miss. He's got that spin and ride to the fastball that guys just swing through. It doesn't lose its elevation and stays above the barrel of the bat. And then he's got the split. He's totally under control all the time."
Maddon has seen Uehara fall behind a hitter and not get flustered "just because he's done it a 100,000 times before."
• Left-hander Brett Anderson, on the disabled list since May 7 because of back problems, threw three innings in a simulated game on Monday at the Cubs' Mesa, Ariz., complex. There is no timetable for his return.
• Cubs closer Wade Davis was placed on the paternity list on Monday and right-hander Dylan Floro recalled from Triple-A Iowa. This is Floro's third callup to the big league team this season. In two relief appearances, he's given up six runs over 6 1/3 innings.
• After C.J. Edwards snared Tommy Pham's line drive for the second out of the eighth inning Sunday night, first baseman Anthony Rizzo went to the mound to check on the young pitcher.
"He came up and goes, 'Hey, man, I just came over here to give you a breather because I know your heart is probably in your stomach now,'" Edwards said Monday. "'I wanted to give you time to catch your breath.' I replied and said, 'Yeah, man, my heart just went to my shoes.'
"It was all reaction. I played it like I knew what I was doing. When I actually threw the ball to 'Riz,' my arm was just shaking. It happened fast. It was crazy."
• Iowa catcher Victor Caratini and Class A South Bend right-hander Duncan Robinson were named the organization's Minor League player and pitcher of the month for May, respectively.
Caratini, 23, batted .366 with six doubles, one triple, three homers, 17 RBIs and five walks in 24 May games. His .366 average ranked eighth in the Pacific Coast League last month, and he led Iowa with a .573 slugging mark and a .971 OPS.
Robinson, 23, went 2-1 with a 1.00 ERA in five games (three starts). He struck out 24 over 27 innings, and threw a season-high-tying seven innings twice, May 9 at Burlington and May 29 against Fort Wayne.
