While the hype surrounding Major League Baseball's free agency period tends to focus on well-known and high-profile players, smaller signings are often just as important.

In a way, low-profile signings can be the difference between a championship team and one that is out of any race before September. 

For the second time in three years, the San Francisco Giants will enter spring training with the feeling of being World Series champions. 

However, there are still some questions that need to be answered and some concerns about the defending champions.

Tonight is a very big game for the Yankees. I don’t like to throw around the cliche that it is a must-win game until it actually becomes a must-win, but tonight is pretty close.

The big series in the standings may be the Yankees vs. the Rays, but judging by the ticket prices on StubHub, the one the fans care about is Yankees vs. Red Sox and we have a good one tonight as Andy Pettitte goes up against Josh Beckett.

Last night in a 7-2 loss to Tampa Bay, Yankees manager Joe Girardi brought in relief pitcher Royce Ring, who was making his debut this season after pitching in Triple-A for most of 2010.

Ring was very effective and efficient, so should Girardi include Ring on the postseason roster?
