First, the offense: Baez hit one of three RBI singles in the second, and he added a two-run homer in the eighth for insurance. He's batting .357 in his past seven games, with four home runs and nine RBIs.
Baez joins Kris Bryant, Willson Contreras, Anthony Rizzo and Kyle Schwarber in the Cubs' 20-homer club, the fourth time in franchise history the team has had five players reach that mark (also 1958, 2004 and '08).
"The way he's swinging the bat, 20 homers for him, that's a big deal for a guy like Javy," Arrieta said. "I expect him to use that as positive reinforcement moving forward. He can do some really great things in this game. I'm happy to have him as a teammate and watch him do his thing every day."
Baez had to play a little cat-and-mouse-game because Blue Jays catcher Miguel Montero knows the infielder well from their days together on the Cubs. He did connect against Tim Mayza with one out and one on in the eighth.
What does 20 homers mean to Baez?
"It means a lot," he said. "I'll try to get 30 if I can. I'm just trying to make my adjustments."
It helps that Baez has gotten more regular playing time, even though it's come at a cost. When Addison Russell was sidelined on Aug. 3, Baez took over at shortstop.
"I just try to do my best," Baez said. "When you play every day, you have a chance to come back the next day and make adjustments. You've got to do what you've got to do for the team. ... I like playing more. We need [Russell], too."
What manager Joe Maddon likes is that Baez is able to forget a bad at-bat or shrug off a botched play quickly.
"He's still prone to that mistake, so you're still going to see it, and you have to play through it -- you have to play through the rough lie sometimes," Maddon said. "He's not a finished product, Albert [Almora Jr.] is not a finished product, [Ian] Happ, [Victor] Caratini -- there's a lot of guys in that lineup who are not finished products."
Baez looked like a Gold Glove shortstop in the ninth when he snared Jose Bautista's hard-hit ball and somehow was able to throw to first in time.
"Two strikes on Bautista, the ball probably had 100-plus[-mph] exit velocity, and to turn it into an out was pretty spectacular," Maddon said of Bautista's ball, which was measured at 106.3 mph, according to Statcast™.
"It's just reaction, really," Baez said. "They didn't think I was going to get to it, and I did get to it. I was more worried about the throw than the play I made."
What's better, hitting home runs or making plays like that?
"I like both, to be honest," Baez said. "I like the fans cheering for me. I love Chicago, and I know Chicago loves me. Thank you for that, and thank you for all the love from the fans."
