Game of the day: Cleveland at Detroit, 7:05 p.m. The Indians have closed to within 1½ games of the Tigers atop the American League Central, making this series the biggest matchup of the weekend. Detroit is just 6-8 since it opened a season-high four-game division lead on Aug. 3, allowing both Cleveland and Chicago to stay close. Right-hander Max Scherzer is scheduled to pitch Friday for the Tigers, and if recent history is any indication Scherzer is due for a loss. Detroit has alternated winning and losing in Scherzer’s last 11 starts, and the Tigers won when he last pitched on Saturday. Right-hander Josh Tomlin (12-5) will pitch for Cleveland, sporting a 6.55 career ERA against Detroit.

Other game to watch: Arizona at Atlanta, 7:35 p.m. The Diamondbacks have played well enough to temporarily exclude themselves from the wild-card conversation, and this series will instead feature a couple of would-be playoff teams if the season ended today. Atlanta right-hander Derek Lowe (7-11) has struggled recently, going 2-5 with a 6.81 ERA over his last seven starts. Arizona right-hander Daniel Hudson (12-8) is set to make his first career start against the Braves.
