Oliver Perez records the first four-strikeout inning in Diamondback history when a dropped third strike allows the first batter to reach base in the seventh frame of the team’s 5-1 loss to Colorado at Coors Field. The 33 year-old Arizona southpaw becomes the 69th different major league hurler to accomplish the feat.

The Royals lose a key home game to the Tigers, 3 – 2, as Max Scherzer defeats James Shields. With the score tied 1 – 1 in the 6th, the Royals have a run taken back when the Tigers make a successful appeal play against Salvador Perez, who fails to retouch third base before going home following a line-out and an error. The Tigers then score twice in the 7th, with a two-out pinch single by Tyler Collins the key blow. The Royals manage to cut the lead by one in the 8th and place two men on with one out in the 9th, but Joe Nathan induces two ground outs to get the save, dealing a serious blow to Kansas City’s postseason hopes.

Jerome Williams does something no pitcher has ever done before: he beats the Athletics for the third time this season – for his third different team. He had recorded a win against the A’s wearing the uniforms of the Astros and Rangers, before earning a 3 – 0 victory for the Phillies today.
