General managers use the offseason to improve their teams at various positions via free agency, trades, waiver claims and international signings. This offseason, we've witnessed more player movement than we've seen in more than a decade, and aggressive GMs throughout the industry have addressed most of their teams' perceived weaknesses and offseason goals.

However, some GMs simply haven't been able to improve certain positions because they didn't match up well with trade partners, they lacked the financial resources in their budget to persuade free agents to sign with them or they just weren't willing to pay the price, in terms of player talent or dollars, to get the deals done.

When this happens, players get opportunities to win a job in spring training that we otherwise didn't think they'd have a shot for. Or in some cases, players simply get a second chance to prove they belong. Unfortunately, it might their last or only chance.

Here are several pairs of players who, at the moment, look like they will get an opportunity to compete for an everyday job because their teams weren't able to address that position this offseason:

1. Wilmer Flores and Ruben Tejada, SS, New York Mets

The Mets were very thorough this offseason, checking in on practically every available and unavailable shortstop in baseball.
