Jon Singleton went 1-for-3 with a walk and a solo home run in Thursday's win over the D'Backs. Singleton belted a second-deck rope off of Wade Miley in the third inning, breaking a 1-1 tie at the time. The rookie now has three home runs in 44 major league plate appearances, slashing .250/.295/.525 with nine RBI.

Jon Singleton went 3-for-4 with a run scored in Tuesday's loss to the Diamondbacks. Singleton eventually scored after leading off the sixth inning with a double, but it was the lone tally for the Astros on the day. The first baseman had three of the team's seven base knocks and their lone extra-base hit. Singleton is batting .265/.286/.500 with two homers and six RBI in his first eight games with the big club.

Jon Singleton went 2-for-6 with a grand slam as the Astros pounded the Twins 14-5 on Sunday. Singleton's ninth inning blast was the second grand slam of the game for the Astros, following Chris Carter's shot in the seventh. It was the first baseman's second home run in six games since being recalled, with all six of his runs batted in coming on homers. It's been an up and down first week, as he's hitting just .200 with a .231 on-base percentage and a 10/1 K/BB ratio to go along with the two bombs.

Jon Singleton homered in his major league debut, and the Astros beat the Angels 7-2 on Tuesday. Singleton looked silly in striking out against C.J. Wilson in his first major league at-bat, but the first baseman worked a bases-loaded walk for his first RBI as part of the Astros' five-run third inning. Later, with the bases empty, Singleton launched a Matt Shoemaker pitch to right field for his first big league blast. Enough hype surrounded his promotion that he's likely been snatched up in most leagues, but he's worth a flyer for his power potential in any leagues where he's still on the wire.

Astros signed 1B Jon Singleton to a five-year, $10 million contract extension. The deal also includes three club options and can be worth up to $35 million if all the options and incentives are triggered. It's a nice safety net for Singleton, but it will wind up being an extremely club-friendly deal if he comes anywhere close to reaching his ceiling. Singleton will make his major league debut on Tuesday.

According to Jeff Passan of Yahoo Sports, the Astros have signed top first base prospect Jonathan Singleton to a five-year contract with three club options. The historic deal -- a first for a player with zero major league service time -- carries $10 million in guaranteed money and can be worth up to $35 million if all the options and incentives are triggered. Singleton, 22, will be promoted from Triple-A Oklahoma City before Tuesday's game against the Angels to take over as Houston's regular first baseman. He was sporting a .941 OPS, 14 home runs, and 43 RBI in 54 games this year at Triple-A and should be owned in all mixed fantasy leagues.

Astros prospect 1B Jonathan Singleton went 2-for-5 with his 13th home run of the season on Monday for Triple-A Oklahoma City. The long ball was Singleton's first since May 12, and it pulled him out of an 11-game skid during which he batted .158 with zero extra-base hits and 12 strikeouts. Overall, the 22-year-old is batting .272/.392/.550 with nine doubles, 39 RBI and a 49/36 strikeout-to-walk ratio through 49 games. He figures to be the next Astros prospect to join George Springer in the major leagues, possibly as soon as next month.

Astros general manager Jeff Lunhow said Wednesday that first baseman Jonathan Singleton is "on deck." Lunhow refused to disclose details, but noted that "when the time is right" Singleton will be promoted to Houston. The Super Two deadline is set to pass in early June. That's presumably when the time will be right. Singleton, 22, is batting .293/.401/.629 with 12 home runs and 34 RBI in 38 games this year at Triple-A.

Astros first base prospect Jonathan Singleton went 2-for-4 with a solo homer on Monday for the Triple-A Oklahoma City. After a brief slump, Singleton has hit .444/.524/.889 with two doubles and two homers over his past five games. More importantly, he has walked eight times and struck out only four times in his past 42 plate appearances. If he can keep his strikeouts down while picking up walks and hitting for power, he could make a big splash in Houston. He is likely to be up in early June.

Astros prospect 1B Jonathan Singleton enjoyed a big game Thursday, going 3-for-5 with a home run and three RBI for Triple-A Oklahoma City. The 22-year-old had been slumping over the last few weeks after opening the season on fire, as he was batting just .192/.348/.385 with four extra-base hits in his previous 16 games headed into Thursday. On the year, Singleton has posted a 1.028 OPS with 19 extra-base hits (11 home runs), 31 RBI and a 33/23 strikeout-to-walk ratio in 33 games for Oklahoma City. With George Springer now manning right field for the Astros, it's seemingly only a matter of time until Singleton joins him in the major leagues.
