Andrew Heaney earned his sixth quality start tonight but allowed two home runs that were the ultimate difference in the Pirates' 3-2 loss to the Cubs at Wrigley Field. 

Heaney set down the first 10 batters he faced before giving up a single to Kyle Tucker in the fourth. After retiring Seya Suzuki with a popout, Heaney threw this high fastball to Pete Crow-Armstrong: 

Crow-Armstrong's 18th home run of the season went 393 feet and gave the Cubs an early 2-0 lead. He hit a similar home run off Heaney on April 29 at PNC Park when he blistered a first-pitch fastball over the Clemente Wall. 

Heaney alternated his fastball and slider for the first four pitches of the at-bat. Both sliders went for a ball and the fastballs were at the top of the zone. Crow-Armstrong swung through the first and fouled off the second before squaring up the last.

"Honestly not surprised. Looking back on it, not a great sequence," Heaney said of the home run despite it being above the zone. "He did that to me in Pittsburgh too. Not terribly thrilled about that selection and execution there, and obviously it ends up kind of costing us the game. Probably some better spots we could have gone to."

Suzuki followed up two innings later when he hit a high changeup into the left-field seats. It's the sixth home run Heaney has allowed since May 26 which is the second-most in Major League Baseball during that time. He's given up 11 all season. 

Heaney only gave up two other hits and struck out seven. He leaned primarily on his fastball (49%) and his slider (29%) while throwing 76 pitches and 54 strikes. He's given up five or fewer hits and three or fewer earned runs in his last three starts. 

"He did a great job and kept them off balance," Don Kelly said. "The pitch to (Crow-Armstrong) was up. He just beat Heaney to the spot there and hit the homer. And Suzuki caught a changeup. But thought he did a really good job mixing the ball in and out and pitched really well." 

• Adam Frazier went 1 for 4 with an RBI but also made a spectacular defensive play in the fourth to rob Suzuki of a base hit:

"He wasn't too close to the wall, but you know, close enough that you feel it," Kelly said. "For him to be able to get all the way over there, slide and make that catch, that was a heck of a play."

Frazier is now hitting .352 over his last 15 games while driving in seven runs. He told me earlier today that he's lowered his hands which has freed him up and allowed him to stay through the ball. 

• Isaac Mattson has gone five straight appearances without giving up an earned run. He threw 1 2/3 innings tonight, struck out one and didn't give up a hit.

"He's just attacking guys. Throwing everything for a strike, getting after the strike zone," Kelly said. "He's competing really well with all of his pitches, too. He's able to throw a lot of different things for strikes."
