What happened: The Chicago Cubs return to Wrigley Field to face the Toronto Blue Jays in the second meeting of their interleague set, with the Saturday game scheduled to air live on Marquee Sports Network. First pitch follows Friday's series opener between the two clubs.

Why it matters: The matchup carries standings weight for both sides as the Cubs, who entered the day above .500, look to build on recent form while the Blue Jays try to climb back over the break-even mark. A strong showing here would help Chicago bank ground in a tightly bunched stretch of its schedule.

What to watch: Watch the lineups and starting pitchers, and whether Toronto's offense rebounds after a lopsided opener.
