Mark Appel, the former No. 1 overall pick acquired by the Phillies from the Astros in the Ken Giles trade, is stepping away from baseball.

Four months after being removed from the Phils' 40-man roster, Appel is taking an "indefinite break."

"I don't know what the future holds. I'm pursuing other things, but also trying to become a healthy human," Appel told Bleacher Report.

"I'm 26, I have a Stanford degree, I have many interests beyond baseball, which I still love, but I have a lot of things I care about. I enjoy challenging my mind. My last four years in baseball have challenged my mind."

Appel's entire professional career has been a struggle. In five minor-league seasons, he had a 5.06 ERA and 1.52 WHIP, allowing nearly 10 hits per nine innings.

While he was in the Phillies' system, strike-throwing was a huge issue. In 122⅓ innings over two seasons on the Phils' farm, he walked 74 and struck out 94.

Appel, who missed most of 2016 after requiring elbow surgery, had consistent problems going deep into games, something that didn't sit well with an organization that has become increasingly focused on economy of pitches.

The Phillies acquired Appel from Houston on Dec. 12, 2015 along with Vince Velasquez, Tom Eshelman, Brett Oberholtzer and Harold Arauz in exchange for Giles. At the time, it looked like a shrewd move for the Phils. Unfortunately, two years later, Appel is out of baseball and Velasquez is still very much a question mark, both from a health and efficiency standpoint.

As for Giles, he's a World Series champion. He pitched poorly in the playoffs but did have a 2.30 ERA with 34 saves in the regular season.

The Phillies pushed to acquire Appel in the Giles trade because of concerns over Velasquez's health history, per sources. The initial return package included Velasquez and young outfielder Derek Fisher, but because of the concerns with Velasquez, the Phils chose to fortify their return with more pitching. Appel was a prime change-of-scenery candidate, but the Phils swung and missed.

In two seasons with the Phillies, Velasquez has been limited to just 39 starts, going 10-13 with a 4.48 ERA and 9.8 strikeouts per nine innings. He's had three stints on the disabled list and was shut down at the end of the 2016 season.

Eshelman has progressed through the Phils' farm system and could end up making some starts in the majors in 2018. Last season, he went 13-3 with a 2.40 ERA in 23 starts, 18 of which came at Triple A Lehigh Valley. Eshelman, whose calling card is his control, struck out 102 and walked just 18 in 150 innings.

As for Appel, barring a surprise comeback, he will go down as one of the biggest busts in recent history. To his credit, he seems to be mentally moving past that.
