Right-hander Matt Manning failed to execute the pitching plan.
Second baseman Andy Ibáñez was responsible for three mental mistakes.
The struggles of Manning, who hung too many middle-middle breaking balls instead of relying on his fastball, and Ibáñez, who forgot how to run the bases and made a crucial fielding error, were the difference in the Detroit Tigers' 10-6 loss to the Tampa Bay Rays in Sunday's series finale at Comerica Park.
The Tigers (49-62) have lost 10 of their past 15 games.
The downfall of the Tigers began in the first inning, when Manning and Ibáñez teamed up to let the Rays take a 3-0 lead.
