The 28-year-old Romine will add another name to the mix of internal candidates to replace the injured Jose Iglesias at shortstop for the Tigers. In a career-high 123 plate appearances with the Halos last season, Romine batted .259/.308/.287 and saw action at third base, shortstop and second base. In his limited time at shortstop in the Majors, Ultimate Zone Rating and Defensive Runs Saved peg Romine as below average at shortstop, but small sample warnings should definitely be applied, as he's played just 189 innings there at the game's top level. Baseball America ranked him as the best defensive infielder in the Angels' system four times from 2007-11.
Alvarez, 24, made his Major League debut last season and posted a 5.82 ERA in 38 2/3 innings with 7.2 K/9, 3.7 BB/9 and a 40.3 percent ground-ball rate. Opposing lefties roughed him up at a .265/.321/.531 batting line, but he's been much better in the minors. At the Triple-A level, Alvarez has a 2.80 ERA with 8.0 K/9 and 1.7 BB/9 in 128 1/3 innings. He was named Detroit's Minor League Pitcher of the Year in 2013.
