Pearce put Baltimore ahead to stay with a two-run drive in the first inning and connected with a man on in the fourth. It was his first two-homer game during a career that began in 2007.
Adam Jones and J.J. Hardy also homered for the Orioles, who hit a major league-leading 46 long balls in June. The four home runs provided Baltimore with a 6-0 lead in the fourth inning against Saunders , who came in 7-0 lifetime against the Orioles.
Jimenez (3-8) allowed one run, none earned, and four hits with seven strikeouts in eight innings. The right-hander walked only one after issuing 30 free passes in his previous seven starts.
Signed to a four-year, $50 million contract in February, Jimenez was 0-4 in nine starts since May 8 and 0-6 with a 6.28 ERA in eight starts this season at Camden Yards.
Saunders (0-5) gave up seven runs and nine hits in five innings. The left-hander is 0-8 over 12 starts since beating Houston last August.
The Rangers' 10th loss in 12 games left them 9-17 in June. Texas has dropped six straight on the road, its longest skid since an 0-6 streak in August 2010.
Baltimore pounced on Saunders immediately. Nick Markakis drew a leadoff walk and Pearce followed with a drive to left. After Saunders got the first out, Jones hit a shot into the left-field seats.
One inning later, Hardy made it 4-0 with his second home run of the season. The shortstop hit 25 last year.
It was 6-0 before Texas got a run in the fifth on a throwing error by Chris Davis, who was playing third base for the first time since 2011. That's because the Orioles were without Manny Machado, who began a five-game suspension for intentionally throwing his bat toward third in a June 8 game against Oakland.
Davis, who usually plays first base, drew Pearce off first base with a hurried throw while Leonys Martin scored from third with two outs.
Caleb Joseph delivered a sacrifice fly in the bottom half.
