Ben Brown (2-2, 1.74) gets the ball for the Cubs opposite Trevor McDonald (2-3, 4.15) at 7:05 PM PT, and the gap on paper matches what's happened on the field this week. Brown's last time out he punched out 5 Giants over 5.1 innings of one-hit, no-run baseball at Wrigley. McDonald has dropped 3 straight starts heading into this one.
Friday set the tone. Michael Busch went deep into McCovey Cove for a 3-run splash homer — only the 4th by a Cub ever and the first since Joc Pederson — and Javier Assad cruised through 6 innings of 1-run ball for his third straight win. The Cubs had been scuffling badly before that (21 losses in their previous 28 games per the Sun-Times), so an opener like this is the kind of breather they desperately needed.
The headline name is Pete Crow-Armstrong. NL Player of the Week, riding a 12-game hit streak at .392/.456/.745 with 5 homers, and he already torched San Francisco for a 2-homer game in the earlier leg of this home-and-home. Ian Happ is heating up too — 4 homers and 5 doubles over his last 8. If Brown gives the Cubs anything close to what he gave them last week, this lineup has the juice to put it away early.
The Giants, meanwhile, are a 28-42 mess trying to patch an outfield together. Heliot Ramos (quad) is still working through a hitting progression in Arizona with no rehab timetable, and Harrison Bader is on the IL hitting .170 before he got hurt. Bryce Eldridge's 9th-inning homer Friday was about all the home crowd had to chew on.

The Cubs rotation is held together with duct tape behind Brown — Boyd, Taillon, Steele and Horton are all sidelined — but he's been the answer to the question they've been asking all year. McDonald has had some peripherals that suggest better days (3.22 xFIP per FanGraphs), but he's walking too many and the Cubs lineup is in no mood to let a wobbly righty off the hook. Chicago should be the play to take the series.
