David Robertson

This MLB offseason offered little in terms of impact pitchers. And as we look to round third base on it, any that were available are now off the market.

The big three closers—Mark Melancon (San Francisco Giants), Kenley Jansen (Los Angeles Dodgers) and Aroldis Chapman (New York Yankees)—all signed with teams. The Chicago White Sox sent starting pitcher Chris Sale to the Boston Red Sox, and the Kansas City Royals shipped closer Wade Davis to the Chicago Cubs.

It has left the market for pitchers looking like August in Death Valley.

Only a few days remain before the MLB trade deadline Monday. Yet there are probably still a couple front offices around the league surveying the market and the tight-knit playoff race to determine whether they should be buyers or sellers leading up to Aug. 1.

If it wasn't clear after the additions of Zach Duke and Adam LaRoche, it's definitely clear after the latest addition:

The Chicago White Sox are going for it in 2015.

After rejecting a qualifying offer to remain with the New York Yankees, right-handed pitcher David Robertson has found a new employer in the Chicago White Sox.

We've now come to roughly the one-month mark, and many teams have already indicated the roles they'll play in the coming weeks.

There's always that dark-horse team that gets in the way of your MLB free agency predictions.

Don't worry; it happens to everybody.

But staying informed on the hottest free-agent rumors makes it easier to decipher which teams will be players for which free agents. Of course, you'll always have those situations like when the Seattle Mariners shocked the entire universe and outbid the New York Yankees for Robinson Cano.

But that doesn't happen often.

With David Robertson heading to the disabled list and an already young and inexperienced bullpen, the New York Yankees must explore the several relief options that still remain on the free agent market in an attempt to upgrade their roster.

Matt Snyder of CBSSports.com reports that the New York Yankees announced Tuesday afternoon that reliever David Robertson is being placed on the DL with a strained left oblique muscle.

On the heels of a season-ending ACL injury to legendary New York Yankees closer Mariano Rivera, it appeared as though the ninth-inning job was there for the taking for set-up man David Robertson. Now that an injury has felled Robertson as well, though, things are as uncertain as ever in the Yankee bullpen.

The Yankees bullpen is not looking too good right now.

First, Joba Chamberlain with the dislocated ankle. Then, Mariano Rivera with the torn ACL,
