With one-fourth of the season in the books, let's have a look around some injury situations and how they might impact the developing trade market.

• The Cardinals and Yankees provide an interesting case study as we enter the second quarter of the season. Both have excellent records and lead their division. Both have sizeable payrolls as well as large portions of those payrolls sitting idle on the DL. Both have had to insert players onto their active roster that they did not anticipate. But, as Derrick Goold of the St. Louis Post-Dispatch well explains, the source of those substitute bodies has been drastically different. While the Yankees spent well over $20MM to bring in players like Lyle Overbay, Kevin Youkilis, Travis Hafner, and Vernon Wells — all of whom are 34 or older — the Cards reached into their minor league system. Remarkably, St. Louis has plugged all of its holes with players making league minimum, including young pitchers John Gast, Shelby Miller, and Seth Maness.
• The Goold piece also includes some valuable insight from GM John Mozeliak. According to Mozeliak, amongst the team's Double-A and Triple-A rosters, "there is almost at any one position, if we needed help at the big leagues, someone we could call on from there." He acknowledges that such cheap, youthful depth cannot always be achieved, and says the team is prepared to pursue other markets as necessary. "I don't want us to go down the path where we feel like we've created this functional model and don't utilize a really robust pro scouting model that makes sure we understand the trade market and understand the free agent market. We can't be scared of those." Yet, by looking internally first, the team has managed to retain salary flexibility to add outside impact down the line. "This organization's way now of staying healthy is not being tied to those outside markets to fill needs," says Mozeliak. "Having some young players step up like they are now gives us additional flexibility when we're going to need it."
• The Cards' internal depth will once again be put to use with starter Jaime Garcia now staring at a strong possibility of season-ending shoulder surgery, writes Goold. Even with fellow starter Jake Westbrook also stuck on the DL, the team has multiple options among its current relief corps and Triple-A rotation that make a look outside the organization unlikely. Of course, it remains to be seen whether Garcia's replacement(s) can match his strong start to the year. He had thrown 55 1/3 innings of 3.58 ERA baseball to open the season. Veteran starter Chris Carpenter is increasingly shaping up as a viable mid-season option for the club. But any setback in his surprising recovery, or hiccups among the team's young hurlers, could lead St. Louis to consider eventually utilizing some of its salary reserves and young minor league depth in a trade.
• The Braves are another National League contender dealing with injured arms. As Matt Snyder of CBSSports.com's Matt Snyder writes, Eric O'Flaherty appears likely to join fellow setup man Jonny Venters as a season-ending Tommy John patient. While the team seems likely to utilize internal options to fill in for the present, the loss of its two late-inning lefties leaves the team with just one southpaw in the pen, Luis Avilan. Ultimately, then, Atlanta could be forced to explore the trade market to re-establish its depth as the season wears on.
• Teams shopping for starters at the trade deadline appear likely to find a limited supply of attractive arms, says ESPN.com's Buster Olney (Insider subscription required). Two Cubs pitchers headline the developing market, with Scott Feldman shaping up as the surprise top option at the moment. (Matt Garza, of course, will begin his potential audition on Tuesday.) In addition to several other well-documented trade candidates in Ricky Nolasco of the Marlins and the Astros' Bud Norris and Lucas Harrell, Olney pegs the Padres' Jason Marquis and Edinson Volquez as likely available. Meanwhile, Bartolo Colon of the Athletics and Cliff Lee of the Phillies could also be dealt, writes Olney, with the A's having other internal options and the Phils still weighing how to proceed with their excellent (but expensive) 35-year-old co-ace.
