The Miami Marlins added a new arm to the starting rotation on Thursday by acquiring Jarred Cosart from the Houston Astros.

Going to Houston will be Jake Marisnick, Colin Moran, Francis Martes and the first overall pick in the 2015 Competitive Balance Draft. Miami also acquired Enrique Hernandez and Austin Wates from the Astros.

Cosart will immediately join the Marlins' starting rotation and will replace either Brad Hand or Jacob Turner. It is likely that the odd-man out will return to the bullpen as both players lack minor-league options.

After a good rookie season in 2013, Cosart has taken a step back and has struggled more this year. In 20 starts this season, Cosart has a 4.41 E.R.A and a poor strikeout to walk ratio. The 24-year old has issued 51 free passes and has only struck out 75 in 116.1 innings pitched.

Hernandez and Wates will likely head to the minor-leagues for Miami for more seasoning. Hernandez is a versatile player that can play the infield and the outfield. He's currently enjoying a great offensive season at AAA with a slashline of .337/.380/.508. Hernandez who is 22 could be an option for the Marlins at some point this season.

Wates is a speedy outfielder who has already swiped 31 bases at AAA this season. He also has good offensive numbers across the board. In the big leagues, there are presently no openings for an outfielder but Wates will likely take over the Marisnick role of being the first outfielder promoted if needed.

Moran was the Marlins' first round pick in 2013 and was considered the third baseman of the future for the team. Marisnick who was acquired in a blockbuster trade with Toronto in 2012 was looked at as a future starting outfielder on the Marlins.
