The Baltimore Orioles' pitching staff is in top form and could be catching the Toronto Blue Jays' offense at just the right time. The Orioles attempt to post their third shutout in four games when they host the Blue Jays in the opener of a four-game series on Thursday. Toronto bridged May and June with a six-game winning streak but has since dropped four of five while being shut out three times.Baltimore yielded a total of one run in taking two of three from the Boston Red Sox while getting solid work from both the starters and the bullpen. The offense was not quite as impressive but did get the hits it needed in the two wins as Adam Jones stayed hot and Chris Davis found his power stroke. The Blue Jays still lead the American League East, but their offense was dominated by the likes of Kevin Correia and Phil Hughes this week after being shut out twice by the St. Louis Cardinals last weekend.TV: 7:05 p.m. ET, RSN (Toronto), MASN2 (Baltimore)PITCHING MATCHUP: Blue Jays LH Mark Buehrle (10-2, 2.04 ERA) vs. Orioles RH Kevin Gausman (1-1, 4.91)Buehrle suffered a tough-luck loss against the Cardinals on Saturday, when he allowed one run on five hits over seven innings and got no run support.
