In case you missed them over the weekend there have been some changes to roster.

 With Alfredo Amezaga tweaking his knee Saturday, the Marlins decided to play it careful, so they have called up Alejandro De Aza from AAA and sent down reliever Carlos Martinez.

 The drops them back to 12 pitchers.

 Fredi Gonzalez said this way they can get by without Amezaga four a couple games. Consensus is that he will be OK and won't need to go on the DL, but they didn't want to be forced to use him with a short bench.

In order to make room for De Aza on the 40-man roster, VandenHurk was placed on the 60-day DL.

In case you are wondering, why Carroll wasn't recalled, a player who is optioned can't be recalled for 10 days.

In other news:

John Koronka was DFA'd after Sunday's game.  I'm guessing he will have no trouble clearing waivers.

The Marlins selected the contract of right-hander Brian Sanches from Triple-A New Orleans, filling the pitching staff vacancy created when the they designated John Koronka for assignment following Sunday's game.

Manager Fredi Gonzalez has said either Burke Badenhop or Hayden Penn will take Koronka's rotation slot and face the Rays Friday. The guess here is Penn gets the call. He's been throwing better than Badenhop of late and has shown consistent glimpses of swing and miss stuff.

As for Sanches, he is deserving of the promotion. In 16 games for the Zephyrs, he went 1-1 with a 2.04 ERA, four walks and 22 strikeouts in 17 2/3 innings. Sanches has been the closer there, saving four games and holding opponents to a .206 average.

If you look at Sanches' major league stats, he tends to walk a few too many hitters but he did do a decent job of striking some out.

We will see what transpires.  But whatever happens, it can't be worse than Koronka having a spot in the rotation.

Brian Sanches' stats.
