Jon Singleton (baseball)

Early life

Singleton played baseball at Millikan High School in Long Beach, California. He committed to play at California State University, Long Beach a few months before the 2009 Major League Baseball draft.

Career

Philadelphia Phillies

The Philadelphia Phillies drafted Singleton in the eighth round, with the 257th overall selection, of the 2009 Major League Baseball draft. He had been projected for selection as high as the second round of the draft, but his senior year statistics caused him to fall. Singleton reported to the Gulf Coast League Phillies, where he played 31 minor league games that year. He spent 2010 with the Single-A Lakewood BlueClaws, where he hit for a .290 batting average, 14 home runs and 77 runs batted in (RBI).

Prior to the 2011 season, Singleton was considered the Phillies' second best prospect by Baseball America.

Houston Astros

On July 29, 2011, the Phillies traded Singleton, Jarred Cosart, Josh Zeid, and Domingo Santana to the Houston Astros in exchange for Hunter Pence. Baseball America designated Singleton as Houston's top prospect following the 2011 season. He was named to appear in the 2012 All-Star Futures Game.

Singleton tested positive for marijuana in June 2012. and had a second positive test for marijuana in December. On January 9, 2013, Singleton was suspended for 50 games due to his second failed drug test. Singleton said that he had grown up around friends who used the drug and that he had been using it "on and off" since he was 14 years old. He spent a month in a rehabilitation center after the second failed test.

Following the 2013 season, the Astros added Singleton to their 40-man roster. On June 2, 2014, the Astros signed Singleton to a 5-year contract that guaranteed him $10 million, and could have been worth as much as $35 million. The extension was the first to be signed by a drafted player with no major league experience. Singleton was promoted from the Oklahoma City RedHawks of the Triple-A Pacific Coast League (PCL) to make his major league debut on June 3.

Singleton made his major league debut for the Astros on June 3, 2014, against the Los Angeles Angels of Anaheim. In his first game, he went 1–3 with a home run, two RBIs, a walk, and two strikeouts. It was his first major league home run, a solo homer off of Matt Shoemaker. On June 8, Singleton lined his first career grand slam off of Glen Perkins of the Minnesota Twins at Target Field to help the Astros to a 14–5 win. Teammates Dexter Fowler, Chris Carter, and George Springer also homered. (Carter's was also a grand slam).

On August 2, 2014, Singleton hit an inside-the-park home run against the Toronto Blue Jays. It was initially ruled an out by the home plate umpire, but was later reversed following a challenge by Astros manager Bo Porter.

The Astros optioned Singleton to the Triple-A Fresno Grizzlies of the PCL to start the 2015 season. On May 13, 2015, Singleton recorded 10 RBIs, including a grand slam and two-run home run against the Albuquerque Isotopes. His 10-RBI game set a Fresno club record, and was one short of the modern-day PCL record, established by Mike Moustakas in 2010. Including the previous two games, Singleton smashed 4 home runs—two of which were grand slams—and 18 RBI over three games. Over a five-day span, Singleton collected 22 RBIs, including the 18 in Fresno's four-game series in Albuquerque from May 12–15.

On November 19, 2016, Singleton was placed on outright waivers by the Astros. He cleared waivers on November 22 and was assigned to Fresno. He played the 2017 season with the Corpus Christi Hooks of the Double-A Texas League, and led all minor leaguers with 500 or more plate appearances with a walk percentage of 21.4%.

In January 2018, MLB announced that Singleton had failed a third test for a drug of abuse and would be suspended for 100 games. In a statement to the Associated Press, Singleton admitted that he had a substance abuse problem: "At this point, it's pretty evident to me that I'm a drug addict. I don't openly tell everyone that, but it's pretty apparent to myself. I know that I enjoy smoking weed, I enjoy being high and I can't block that out of my mind that I enjoy that. So I have to work against that." On May 21, 2018, Singleton was released by the organization, while serving his suspension, during the final year of his contract.
