Philadelphia Phillies minor league pitcher Mark Appel has been placed on the disabled list due to a strained right shoulder, according to Todd Zolecki of MLB.com.
The 25-year-old Appel is currently in Triple-A Lehigh Valley.
The right-hander has started 17 games this season, going 5-4 with a 5.27 ERA over 82 innings of work. He has allowed 91 hits while issuing an excessive 53 walks, resulting in an alarming WHIP of 1.756. Appel has only struck out 60 batters.
The Houston native, who played his college baseball at Stanford University, was originally selected by the Detroit Tigers in the 15th round of the 2009 MLB June Amateur Draft. However, he failed to sign, and three years later, he was picked by the Pittsburgh Pirates in the first round of the draft. Once again, Appel did not ink a contract, and the following year, he was drafted in the first round by the Houston Astros.
Appel spent three years in the Astros’ organization and was considered an elite prospect during his tenure with the club.
In 2014, he was ranked the 39th best prospect in the majors by Baseball America, 17th by Major League Baseball and 21st by Baseball Prospectus. He remained in the top 35 for all three publications in 2015, and in 2016, he was ranked 70th by Major League Baseball and 64th by Baseball Prospectus.
In spite of his high rankings, Appel never lived up to his lofty expecations.
Over 79 career minor league games, 78 of them being starts, Appel has gone 24-18 with a lifetime 5.09 ERA and 1.521 WHIP.
He arrived with the Phillies’ organization in December 2015 in a deal that sent Ken Giles to the Astros.
