Diekman’s Sizzling Fastball
He struck out the only two batters he faced in the eighth inning in Saturday’s 6-5 victory over the Braves at Citizens Bank Park. He has allowed five hits, one run, two walks and struck out a remarkable 18 in 11 2/3 innings in his last 12 appearances.
He has been impressive as he has touched as high as 99 mph on the home radar gun. In fact, according to FanGraphs, Diekman’s average fastball velocity is third best among Phillies pitchers from 2002-13. His fastball his first two seasons in the big leagues has averaged 95.4 mph, which trails only Billy Wagner (96.7 mph) and Felix Rodriguez (95.6 mph). Wagner pitched for the Phillies from 2004-05. Rodriguez made 23 appearances for the Phillies in 2004.
Interestingly, five of the pitchers in the top 10 have pitched for the Phillies this season: B.J. Rosenberg (94.8 mph) is fourth, Phillippe Aumont (94.7 mph) is tied with Francisco Rosario for fifth, J.C. Ramirez (94.1 mph) is ninth and Luis Garcia (94.0 mph) is 10th.
And for those interested, of the 128 pitchers available to FanGraphs, former Phillies infielder John McDonald ranked last at 78.3 mph. Jamie Moyer ranked 127th with an 81.2 mph fastball.
