No matter how you frame it, potential contenders have holes to fill

The Minnesota Twins signed Jason Castro to a three-year, $24.5 million deal in November in spite of a rough history as a hitter, and at least partly because Castro has been one of the dominant catchers in pitch-framing statistics, which theoretically reflects the ability to present pitches to umpires in a way that makes them look like strikes.

Castro ranked fifth among all catchers last season in one pitch-framing metric, as compiled by Catcher Report, after finishing in the top 10 the year before. During the postseason, Cleveland catcher Roberto Perez seemingly turned borderline pitches from Corey Kluber, Josh Tomlin, Ryan Merritt and other Indians pitchers into strikes, a performance thought to have made the difference for the Indians as they advanced to Game 7 of the World Series.

Wieters is looking for a job now, at a time when the Orioles are looking for a frontline catcher, one of the 10 biggest holes in the market among teams that are working to contend in 2017.

Among 36 pitchers with at least 30 postseason innings pitched since 2010, Davis ranks first in ERA and strikeouts per nine innings pitched (12.8). He has only allowed one home run in his postseason career, and that was to Nelson Cruz back in 2010 when Davis pitched for the Tampa Bay Rays.

Davis was limited to 43 1/3 innings last season, a low for him since moving to the bullpen full time. His ERA nearly doubled from 2015 to 2016 (0.94 to 1.87), but he had a 2.29 FIP (fielding independent pitching) in each of those seasons.
