Jeff Locke allowed three earned runs over five innings Saturday in the Pirates' loss to the Nationals. Locke threw seven shutout innings against the Cardinals on April 28 and six scoreless against the Phillies on April 23. But he fell back down to earth against the Nats on Saturday afternoon. The 25-year-old lefty has a 3.21 ERA and 1.25 WHIP in 33 2/3 innings this season. We would expect some more regression.
