David Bote hit a tying, two-run homer off Brad Boxberger with one out in the ninth inning, Anthony Rizzo followed two pitches later with a winning home run and the Chicago Cubs overcame a five-run deficit to beat the Arizona Diamondbacks 7-6 on Thursday.
Bote was called up when Kris Bryant was put on the disabled list Thursday because of inflammation in his left shoulder. Bote drove a thigh-high 0-2 fastball about a half-dozen rows in the bleachers in left-center for his second home run this season, tying the score 6-6.
Rizzo took a strike, then sent a thigh-high changeup to the top of the bleachers in right-center. Boxberger (1-4) blew a save for the fifth time in 29 chances.
Nick Ahmed hit his first career grand slam in the fifth, an inning after Alex Avila's two-run homer, as the Diamondbacks built a 6-1 lead.
Chicago got two runs in the fifth on Anthony Rizzo's RBI single and run-scoring grounder by Albert Almora Jr., who reached when third baseman Daniel Descalso allowed his potential inning-ending, double-play grounder to bounce away for an error.
Kyle Schwarber scored from third base with two outs in the sixth when Javier Baez reached while striking out as Zach Godley bounced a breaking ball for a wild pitch.
Eddie Butler (1-1), the fifth Chicago reliever, retired Jon Jay on a flyout that stranded two runners in the ninth.
Cubs starter Tyler Chatwood allowed four runs, five hits and six walks in 4 2/3 innings. Chatwood leads the major leagues with 85 walks and has a 7.71 ERA in his last five starts.
Godley gave up four runs and seven hits in 5 2/3 innings.
