The Los Angeles Dodgers are adding an arm, but their latest move comes with considerably more uncertainty than immediate help. That gives Los Angeles some valuable flexibility, especially for a front office accustomed to stashing injured pitchers with the hope of unlocking them later. Dodgers' trade for injured Royals pitcher Kris Bubic raises more questions than answersBubic has spent his entire seven-year major league career with the Royals, recording a respectable 4.14 ERA over 522 innings. But this is still a questionable deadline move if Los Angeles is counting on him for meaningful innings down the stretch. For a contender trying to survive October, another injured pitcher feels more like a gamble than a solution.
