With their six-game winning streak in the past, the Blue Jays attempt to bounce back as Dickey tries to win his third straight start Saturday night against the Houston Astros.Toronto (60-51) scored 12 runs with Dickey (9-10, 3.91 ERA) on the mound during a stretch where he lost six of seven but posted a 3.54 ERA. That lack of support ended when the Blue Jays scored five runs while Dickey allowed four in six innings of a 6-4 victory over Boston on July 23.They then gave the right-hander plenty to work with while he yielded a run, three hits and struck out 10 in seven innings of a 14-1 rout at Fenway Park on Monday."I kind of wish they could divide (the runs) up over, like, three starts," Dickey said. "I'll take that every time out."The Blue Jays managed one run with Dickey on the hill as he gave up five on two homers in seven innings of a 6-4 loss April 10 that dropped him to 2/3 with a 4.45 ERA in eight starts against Houston (45-65).Toronto averaged 6.2 runs and 10.9 hits while winning 11 of 13 before its winning streak ended with six hits during a 3-1 loss Friday. Dioner Navarro drove in the run as the Blue Jays fell to 6-2 on a 10-game trip.Navarro is batting .352 with 13 RBIs over his last 18 games and .342 in 11 career contests at Minute Maid Park.Houston's Gregorio Petit hit his first career homer to break a 1-all tie in the eighth Friday. The infielder is 4 for 13 with two RBIs in four games since he was recalled from the minors to see his first major league action since 2009 with Oakland.Teammate Brett Oberholtzer (3-7, 4.30) went 0-6 with a 5.68 ERA in his first seven starts before being sent down to the minors for the first time this season. Since then, he's 3-1 with a 3.15 ERA over his last seven outings, which were interrupted by two more trips to Triple-A Oklahoma City.The left-hander allowed three runs in 6 2/3 innings of a 7-3 victory over Oakland on Monday to improve to 2-0 with a 2.39 ERA in four home starts after going 0-3 with a 9.64 ERA there. He's completed at least six innings in eight straight outings overall."Obviously if you go deeper into the game, you're doing something right for the team," Oberholtzer told MLB's official website.During his only appearance against Toronto, Oberholtzer lasted 5 1/3 innings while giving up three runs, three hits, three walks and striking out three in a 5-2 loss April 8.Houston's Jose Altuve went 1 for 4 a night after his 12-game hitting streak ended during Thursday's 6-5 loss in the series opener. He's batting an AL-leading .339 but is 0 for 10 against Dickey.
