The Jays’ resurgence the past month has been led by starting pitching, and right hander Chien-Ming Wang kept it going Saturday afternoon.

Wang worked one out into the seventh inning and was a ground ball machine, defusing a potent Baltimore Orioles lineup with his sinker in the Jays’ 4-2 win before an announced crowd of 43,261 at the Rogers Centre.

Wang’s effectiveness has been a bonus for the Jays, who signed him after Brandon Morrow went down to a forearm injury two weeks ago. Making his third start since Morrow’s loss, Wang has worked into the seventh each time thanks largely to a sinker that breaks back over the plate with a slight screwball action.

That pitch induced 14 ground ball outs and was a huge factor in the Jays edging a very good O’s ball club. The win extended the club’s win streak to 10 games, matching the second longest in franchise history and one off the team record.
