Injuries and poor performance has kept the charter between New Orleans and Miami busy early in the season. John Maine was the latest roster causality for the Miami Marlins. The team decided to designate Maine for assignment after he was lit up by Cincinnati Red bats last night. Tom Koehler was called up to take Maine’s spot.

The 31-year old right hander pitched a total of 7 1/3 innings for the Marlins over the course of four appearances. Maine did not pitch well at all for the Marlins, as he allowed 10 runs on 15 hits and five walks, leading to an ugly 12.27 ERA and a 6.76 FIP. Maine also struck out seven hitters, but struggled to do much else right.

Maine pitched in relief of Jose Fernandez last night, entering the game in the bottom of the fifth. Maine lasted just two innings, allowing six earned runs allowing four hits and five walks. Maine only made one appearance in which he did not allow a run with the Marlins. That appearance was his first one of the season, and the first since 2010, against the Atlanta Braves.

Koehler, who was a candidate for the final starting rotation spot this spring, has made three starts in Triple-A New Orleans on the season. He has struck out 14 hitters in his 17 innings of work, allowing just two earned runs, good for a 1.06 ERA. He has struggled with command at times, walking 10 batters and allowing seven hits.

The Marlins will use Koehler in the long relief role that Maine had been in. Earlier this year, I ranked Koehler as the Marlins 18th best prospect. Here is what I had to say about Koehler:

"Tom Koehler is a tad bit old to be a prospect at the age of 26, but he is an underrated pitcher and has the stuff to be a four/five pitcher, or an effective reliever. He showed some of that promise last September when he received a call-up. Koehler pitched decent, though his MLB numbers would suggest otherwise. Seven of the eight runs he allowed came across two games, five out of the other six appearances Koehler did not allow a single run. Koehler also made one start, as a fill in for Mark Buehrle."

Koehler will be presented a chance to hold down a job in the Marlins struggling bullpen. Hopefully he does well and provides some stability to the Marlins pen.

Interestingly enough, the Marlins were never interested in Francisco Rodriguez, according to Juan C. Rodriguez of the Sun-Sentinel.

K-Rod signed a minor league deal with the Brewers yesterday. The team did sign former Seattle Mariner closer David Aardsma to a minor league contract earlier this week.

The Marlins current 40-man roster now sits at 39, potentially leaving one spot open for a potential roster move in the future. Stay tuned.
