The Cardinals’ roster is looking a little different again today.

Matt Carpenter and Mark Hamilton were called up from Triple A Memphis, to take the spots of Maikel Cleto and Pete Kozma. Cleto was sent back to Double A Springfield, while Kozma returned to Memphis.

Here’s a look at Carpenter from Matthew Leach at Cardinals.com:

Carpenter was a Spring Training sensation and very nearly made the Major League roster out of camp. He got off to a slow start in the regular season, but is currently hitting .283 with a .421 OBP and a .387 SLG at Memphis. Carpenter was the Cardinals’ Minor League player of the year in 2010.

Hamilton was with the Cards for a while last month, as Leach writes:

He went 3-for-15 earlier in 2011. Over parts of three seasons at Triple-A, however, Hamilton has shown himself to be an offensive force. In 25 games at Memphis this year, he’s batting .391 with a .509 on-base percentage and a .552 slugging percentage. His career Triple-A line is .318/.409/.564 with 26 home runs in 143 games.

Kozma appeared in 10 games, mostly off the bench, while Cleto made his debut last night.

Both Carpenter and Hamilton will be available for tonight’s game.

And speaking of tonight, join us for our live game thread as the Cards hopefully beat up take on the Cubs. Check back later for a guest post from Julie DiCaro of A League of Her Own, which will most certainly include some bashing of Ryan Theriot. Be sure to remind her that THERIOT HAS A 16-GAME HITTING STREAK (since that’s about the only positive there is).
