PHOENIX -- Not many players go from the Minor Leagues to a No. 3 hitter for a Major League club quickly, but that's what Astros first baseman Jon Singleton has done in the span of a week.
With fellow rookie slugger George Springer out for the second straight game, Singleton has taken up the third spot in the lineup against the D-backs.
"Jon Singleton is a really good player," manager Bo Porter said. "You look at even him getting plugged into the three-hole [Monday], it was more centered around Springer getting scratched, but he's been swinging the bat well."
As the No. 3 hitter in the Astros' 4-3 win against the D-backs on Monday, Singleton went 1-for-5 with a strikeout, but he also came around to score a run.
Singleton's first week in the Major Leagues has been an eventful one. He's already appeared on highlight reels thanks to his first big league grand slam, which came on Sunday against the Twins, and was part of a pair of grand slams in the same game. Teammate Chris Carter also hit one.
"Really, I'm just having fun," Singleton said. "I'm just glad to be here and taking it all in. It's a great experience."
Although Singleton has made a quick splash, he's not lighting up the league with his numbers. Through seven games, he has a .200 batting average and a .659 OPS.
Cold streaks to start careers aren't anything new -- Springer struggled when he was first called up before going on a tear and hitting 10 home runs in May.
Singleton isn't resting on his laurels now that he's with the Major League club. Before Monday's and Tuesday's games, Singleton has spent time watching video.
"I'm just watching it to see what's going on," Singleton said.
The Astros have been on a roll lately, winning six of their last 10 and 18 of their last 30. Singleton hasn't been a part of all those games, but he's certainly enjoying the ride.
"It's pretty cool," Singleton said. "We all want to go out and win, so we can all do our part and can definitely help the ballclub win."
