It's been a sort of whirlwind week for Halsey, who has benefited from a gloomy forecast. If rain forces the A's to play a doubleheader against the Yankees this week, as widely expected, then they will need a spot starter on Saturday in Seattle. Thus the A's deviated from their original plan to carry 11 pitchers, creating room on the roster for Halsey.The A's haven't had much time to evaluate Halsey while wearing their jersey -- he threw a perfect seventh inning on Sunday -- but Macha noted that he has been impressed with the 25-year-old since seeing him in Spring Training last year. Halsey will also be available out of the bullpen through Wednesday in case a doubleheader taxes the pitching staff. Whither the weather? The A's continued to brace for the possibility of an Opening Day rainout -- as of Sunday afternoon, the National Weather Service forecast called for a 60 percent chance of rain in Oakland at game time on Monday. While the rainy weather that has plagued the Bay Area over the last month has been record-setting, and the A's have had only 19 rainouts in their 38-year history at McAfee Coliseum, Macha wondered one thing. "When you open up on the East Coast, they always plan [an off-day after Opening Day] so that they can keep the Opening Day gate," he said. "We don't have an off-day here to protect us from that." Briefly: The A's suggested using the designated hitter for Sunday's game so that Frank Thomas could get in a few more preseason at-bats. The Giants agreed, knowing it would give Barry Bonds the same opportunity. Thomas went 0-for-2 with a walk and finished his abbreviated spring with two hits in 12 at-bats. ... During the three-game Bay Bridge Series with the Giants, the A's batted .292 (31-for-106) and scored 23 runs. ... The A's concluded the exhibition season 15-17.
