On 4/22 in Baltimore, Loiaza pitched around an error by Jose, I think, and definitely an infield hit caused by Jimenez' nonchalance.
Loiaza has definitely gotten much better defensive support than Mark, but sometimes it's up to the pitcher to pitch around an error. Of course, Buehrle can't be blamed for that horrible inning in Toronto and Jimenez's muff of a pop-up in Oakland.
