UPDATE (8:35 pm PST on Monday): Called on in the sixth inning with the score tied 5-5, Adam Duvall hit a pinch-hit, two-run home run in his first at-bat for the Reds. Cincinnati would go on to defeat the Cubs, 13-6.

CHICAGO -- After placing outfielder Brennan Boesch on the disabled list with an ankle contusion late Sunday, the Cincinnati Reds promoted outfielder/infielder Adam Duvall from Triple-A Louisville on Monday.
In another move, the Reds recalled right-hander Michael Lorenzen from Louisville and optioned David Holmberg there.
Duvall was acquired from San Francisco on July 31 along with pitcher Keury Mella for pitcher Mike Leake.
Duvall hit 30 home runs with 87 RBIs in 125 minor league games this season.
Lorenzen - who has a 3-8 record and a 5.46 ERA this season - was Cincinnati's starter on Monday night against the Chicago Cubs.
