I've gotten so many of these ATCRCS cards back in the past few weeks, it is hard to decide who to write about next. Alphabetical sounds good for now so I'll go with Mitch Atkins. The Cubs drafted him in the 7th round of the 2004 draft. He hit all the stops along the way, Boise, Peoria, Daytona, Tennessee and Iowa before making his MLB (and Cubs) debut on July 29, 2009. He pitched a perfect inning in a 12-0 blowout of the Houston Astros to finish the game. The next day, he gave up one hit but still pitched a scoreless inning in another Astros blowout, this time 12-3. And that was his season...
I don't remember the details behind a roster move but he spent the rest of the season in Triple A Iowa. The following season, he pitched ten innings over a span of five midseason games. He gave up at least a run in four of the five appearances, so not as well as his debut.
He was granted free agency at the end of the season and signed with the Baltimore Orioles. He didn't really catch on there either, pitching 10.2 innings over three games in 2011. Again a free agent, he spent all of the 2012 season with the Washington Nationals Triple A affiliate, the Syracuse Chiefs.
Atkins started the 2013 season with the Somerset Patriots, a team in the independent Atlantic League. This card was signed with a little help from a member on SCN who regularly 'graphs that league. Atkins has since signed with the Atlanta Braves and is currently with their Double A team, the Mississippi Braves. He is 4-1 in 10 starts since signing in June.
