Cardinals top prospect Shelby Miller now pitching at Double-A


The Cardinals selected Texas high school pitcher Shelby Miller with the 19th overall pick in the 2009 MLB Amateur Draft, confident that his sharp high-90s fastball could one day make him a major league ace.

That day may be coming soon.

Miller was promoted to Double-A Springfield last week after opening the 2011 season with a 2.89 ERA and a dominant 81/20 K/BB ratio over 53 innings at High-A Palm Beach. He struck out 140 batters in 104 1/3 innings last season with Low-A Quad Cities, issuing only 33 walks along the way.

This winter, Baseball America rated Miller as the 13th-best prospect in baseball. ESPN’s Keith Law had him as baseball’s No. 4 prospect last week.

The 20-year-old right-hander made his debut for the Springfield Cardinals on Friday in front of friends and family in Corpus Christi, Texas. He allowed just one earned run over six strong innings, fanning five batters against two walks and scattering seven hits to earn his first career victory above the Single-A level.

Derrick Goold of the St. Louis Post-Dispatch ran a quick profile of Miller late Saturday night. The Cardinals, who preach a pitch-to-contact approach with most of their starters, have been slowly molding his off-speed stuff to be as effective as his signature heater. Instead of throwing a looping curveball like he did in high school, Miller now has a “power curve” that is tighter and pairs better with his fastball.

Miller could jump to Triple-A Memphis by the start of next season and could arrive in the majors by mid-2012.

Royals’ Opening Day starter Danny Duffy weathered a minor scare during Saturday’s Cactus League game against the Diamondbacks. The left-hander was removed from his final spring training start after experiencing some left shoulder tightness in the second and third innings. No lasting damage appears to have been done — Duffy told reporters that he simply felt a slight ache, nothing more — and it looks like he’ll remain on track to open the season with the team next Thursday.

The 29-year-old southpaw is coming off one of his best performances to date. Despite losing a few weeks to an oblique strain and elbow soreness, he went 9-10 in 24 starts and finished the 2017 season with a 3.81 ERA, 2.5 BB/9 and 8.0 SO/9 over 146 1/3 innings. While Duffy entered camp with a clean bill of health, he struggled to execute against his spring training opponents and racked up 13 runs, four homers, seven walks and 11 strikeouts in 13 innings of Cactus League play.

The Royals are scheduled to kick off their home opener against the White Sox on Thursday, March 29 at 4:15 PM ET. Barring any further complications with his shoulder, Duffy will take the mound for the Royals, while James Shields is expected to make his first Opening Day appearance for the White Sox.
