JAN. 24: Jon Heyman of CBS Sports tweets that Colvin's physical revealed that he still has back issues, causing the Orioles to reduce their offer from a Major League contract to a minor league deal. As such, Colvin will not sign and remains a free agent. Heyman points out that Colvin can now seek a big league deal with a club, knowing that he can sign a minor league pact with the O's as a fallback (Twitter link).

JAN. 22: A source tells ESPN.com's Jerry Crasnick (Twitter link) that the Orioles found an issue with Colvin's physical, which could be creating an obstacle to the deal.

JAN. 15: The Orioles have agreed to terms with free agent outfielder Tyler Colvin, reports Dan Connolly of the Baltimore Sun (Twitter links). Only a physical stands in the way of the deal, Connolly says, which is believed to be a guaranteed MLB contract. Colvin, 28, is represented by Relativity Baseball.

The left-handed swinging Colvin has seen MLB action in parts of five seasons. In 2012, his first year with the Rockies, Colvin posted a promising .290/.327/.531 triple-slash in 452 plate appearances. But he took a step back last year, earning only 78 MLB plate appearances and registering a meager .160/.192/.280 line in the process. He continued to hit at the Triple-A level, however, slashing .275/.377/.480 in 269 trips to the plate for Colorado Springs.

Colvin started his career with the Cubs before heading to Colorado in the Ian Stewart trade. The 13th overall choice in the 2006 draft, Baseball America considered Colvin the game's 75th-best prospect after the 2007 season.

Colvin joins a long list of outfielders that will join the O's for Spring Training. (The Sun's Eduardo Encina counts 12, on Twitter.) Other offseason outfield additions include Delmon Young, Quintin Berry, Xavier Paul, David Lough, and Francisco Peguero.
