MLB Team Report - Houston Astros - INSIDE PITCH

HOUSTON -- The Houston Astros continued their roster shuffling Friday, promoting touted right-hander Mike Foltynewicz while also welcoming center fielder Jake Marisnick, acquired as part of a six-player trade with the Miami Marlins on Thursday at the non-waiver trade deadline.

Foltynewicz went 7-7 with a 5.08 ERA over 21 appearances (18 starts) with Triple-A Oklahoma City, numbers that don't necessarily reflect the need for a promotion. But Foltynewicz is ranked as the Astros' fourth-best prospect and, with two players shipped to Miami (right-hander Jarred Cosart and super-utility Kike Hernandez) there was a roster spot available. Foltynewicz will work out of the bullpen in the foreseeable future.

"It's definitely going to be an adjustment, especially at the big league level," Foltynewicz said. "I relieved in spring training so I kind of got used to it there. I'll just take it step by step and we'll go from there.

"It's going to be a different mentality coming out of the bullpen than starter and to be a pitcher instead of going out there trying to throw as hard as I can. It was the same mentality when I was a reliever. I'm going to have to start using my off-speed right away to guys and know it's a different approach to hitters."

Marisnick, originally drafted by the Blue Jays in the third round in 2009, has only sparse experience in the big leagues, compiling just 169 plate appearances over two seasons with the Marlins. Such a small sample size doesn't offer much of a glimpse of his potential with the Astros, who immediately inserted Marisnick into the lineup on Friday.

"If you go back and look at my track record my first 100 at-bats everywhere I've been it's been an adjustment period," Marisnick said. "Once you start getting a certain number of at-bats I start to adjust and see what pitchers are trying to do. I've done it my whole career; I've been able to make adjustments. I'm not worried at all. I think I'll be good."
