After missing much of the year recovering from Tommy John surgery, it appears that Danny Duffy is ready to claim a spot in the Kansas City Royals’ rotation for the rest of this season and possibly next season as well.
Duffy, who has replaced the struggling Wade Davis in the starting rotation, shut down the Twins in his latest start. He pitched 6.2 innings, allowing just five hits and no runs, while striking out seven. Perhaps the most important stat from that start, however, was that Duffy did not allow a walk. It was the first start in his career that he didn’t issue a free pass.
The knock on Duffy has always been his lack of control. And pitchers that come back from Tommy John surgery tend to struggle finding a feel for the strike zone initially. In his only other two starts this season, Duffy walked two batters in 3.2 innings and three batters in 6 innings.
In Duffy’s three years pitching in the majors, he has a walk rate of 4.5/9. While the walks tend to pile up for the talented southpaw, he has always shown strike out potential, with a strike out rate of 8.0/9 for his career.
Duffy was drafted in the third round of the 2007 draft and coming into the 2011 season, he was ranked as the 68th best prospect in baseball according to Baseball America. So the potential has always been there.
The 6-foot-3 lefty spent six years in the minor leagues, earning 30-16 record, with an impressive 2.88 ERA and 1.15 WHIP. His minor league K/9 is 10.6 and his BB/9 is 3.0, considerably less than his 4.5 mark in the majors.
Duffy debuted in 2011, starting 20 games and finishing with a 4-8 record and a 5.64 ERA. He showed improvement in 2012 before his injury. He started six games and recorded a 3.90 ERA.
While the Tommy John injury delayed his development, Duffy appears to be back on track. He has a chance to show that he is a big part of the Royals’ future. If he can finish this season strong and continue to improve with his control, he should lock up a spot in next year’s starting five and perhaps beyond.
