Since joining the Red Sox last year, John Lackey was 1-3 with a 9.40 earned run average in five starts against the Blue Jays. In his first start against the Jays this season, May 11, he allowed nine runs over 6 2/3 innings and went on the disabled list five days later. He returned to the Rogers Centre mound yesterday armed with some new ideas about how to pitch to the Toronto hitters. After watching video of his previous starts, Lackey noticed he had fallen into predictable patterns with how he sequenced pitches.
