Zeid is a 27-year-old righty who has made over twenty appearances in each of the last two years for Houston. After a solid, if unspectacular 2013, he hit a wall last year with a 6.97 ERA and 6.33 FIP in 20 2/3 innings. While Zeid’s K:BB numbers (7.8 strikeouts and 3.0 walks per nine) were not problematic, he allowed 13.1 hits per nine and surrendered a troubling 27.3% HR/FB rate. On the positive side, both his xFIP (3.87) and SIERA (3.64) marks were within range of league average.
Carrera, also 27, swings from the left side and has seen scattered MLB action over the last several years. All told, he owns a .253/.305/.340 line through 478 total MLB plate appearances. It would seem that his usefulness in Detroit was undermined by the addition of Anthony Gose.
