by Jeff Lippman | CBSSports.com (3/4/2013) Oakland relievers Ryan Cook and Sean Doolittle may be competing for saves early in the season for as long as Grant Balfour is out. There is no guarantee that Balfour misses any regular-season time, but he's out for the time being and is questionable to be healthy to begin the year. Doolittle and Cook each pitched on Monday against the Angels in Cactus League competition. Doolittle pitched the fourth inning and went 1-2-3 with three strikeouts. Unfortunately, Cook struggled as he allowed three earned runs on four hits and a walk over his inning. Vernon Wells took Cook deep in the fifth for a three-run shot. Cook did strike out one batter.
