Mike Foltynewicz and Jake Marisnick activated for tonight’s game

The Astros have filled the two open roster spots left vacant by the trade that sent Jarred Cosart and Kike Hernandez to Miami. Michael Foltynewicz and Jake Marisnick will be in Houston for tonight’s game against the Toronto Blue Jays.

Marisnick, who came over in the deal with the Marlins, will get a chance to play every day in the Astros outfield. Marisnick should be in centerfield tonight, and every night, until Dexter Fowler is healthy and able to play. Rated as high as the Marlins’ #3 prospect, the 23-year old fly chaser has been described as anything from a 5-tool player to a bust. We’re about to find out which category he actually fits into.

Foltynewicz, rated the Astros #4 prospect, will be pitching out of Bo Porter‘s bullpen. The 22-year old flame thrower has moved quickly through the Astros system since being drafted in the first round of the 2010 draft. Folty has struggled a bit in his first season at the AAA level, posting a 5.08 ERA and a 1.46 WHIP in 21 games (18 starts).

On the decision to put Folty in the bullpen, JeFF Luhnow told Brian McTaggart:

"He’s refined his offspeed stuff and has been able to work on a lot of different things. We’re going to pitch him in the bullpen here for the remainder of the year, and that will give him an opportunity to get his feet wet at the Major League level and show us what he’s got. He’ll help us win some games."

Astros fans have been clamoring to see Mike get his chance. I will be at the game tonight and hoping to see Folty’s big league debut.
