Pitching style

Alburquerque is a three-pitch pitcher. He throws a hard four-seam fastball that ranges between 94–98 mph, and his "out pitch" is a downward-breaking slider that ranges between 85–88 mph. The slider is his most common pitch, especially with two strikes in the count; it has a 60% whiff rate, the fifth-highest for a slider among relief pitchers since the 2007 season. His best pitch is what scouts call the "Cross Curve" that "breaks this way, and then that way." His strikeouts per 9 innings pitched ratio is above the league average, sitting at 11.0 through the end of the 2015 season. He also has a high walk rate at 5.0 per 9 innings. Alburquerque was effective in the 2011 season at stranding inherited baserunners, allowing only 3 of 31 to score.
