The Pirates have rounded out their rotation by naming Jeff Locke their fifth starter, reports Rob Biertempfel of the Pittsburgh Tribune-Review.
The addition of the 25-year-old left-hander to the starting five means that the Pirates will open the season with three lefties in the rotation -- Locke, the recently anointed Jonathan Sanchez and Wandy Rodriguez.
Locke has logged just 12 games at the major-league level (10 starts), and over that span he's posted an ERA of 5.82, a WHIP of 1.53 and a K/BB ratio of 1.86. Across parts of seven minor-league seasons, Locke pitched to a 3.60 ERA, 1.26 WHIP and 3.35 K/BB.
According to the various projection systems available at FanGraphs, Locke should be good for a solid K rate and an ERA that ranges from the high 3.00s to 4.68.
