Beckham’s two-run drive highlighted a five-run fourth against Jon Lester (5-5). Alex Colome gave up two runs in the ninth, but the Rays won their first meeting against Maddon since he left to manage Chicago following the 2014 season.
Colome threw 38 pitches in the ninth but came away with his 22nd save in 26 chances.
Chris Archer (7-5) picked up his third win in four starts, giving up three runs and eight hits in six innings. The former Cubs prospect also had an RBI single for his first career hit.
Lester allowed up six runs — tying a season-high — and nine hits over five innings. Chicago lost for the fifth time in seven games.
Maddon led Tampa Bay to a 754-705 record, four playoff appearances, two AL East titles and the 2008 AL pennant in nine seasons. His first two years in Chicago were nothing short of spectacular, with the Cubs reaching the NLCS in 2015 and bringing home their first World Series championship since 1908 last fall.
But the Cubs have hovered around .500 all season. And on Tuesday, one big inning led to another loss.
The Rays sent nine batters to the plate in the fourth to break a 1-1 tie.
Trevor Plouffe led off with a single and Beckham drove the next pitch to the center-field basket for his 11th homer.
Archer, hitless in his first 23 career at-bats, added an RBI single. Souza’s sharp grounder then ricocheted off Lester’s glove, resulting in a two-run double that made it 6-1.
RBI singles by Bryant and Zobrist in the fifth cut it to 6-3.
Cubs: RF Heyward was activated from the 10-day DL after being sidelined since June 18 because of a laceration on his left hand.
