On Twitter, Matthew Mowery of The Oakland Press drives home just how fragile Guillen has been over the past four seasons.
Carlos Guillen played 284 of a possible 605 games during his current four-year, $48 M contract w/ #Tigers. Missed 1st 93 games this season.
Will Rhymes is being called up. He was sent down to Toledo in May after hitting just .221 in 19 games. His line at Toledo this year is .303/.373/.398/.771 (with three home runs!), similar to what it was when he got his first call up last year.
Guillen is barely over the Mendoza line, and hitting 4-38 with one RBI in his last ten games, so it's not surprising there's something wrong.
