The other night at the game in Pittsburgh, my former roommate David Aceto and I checked the OBAs of the starters in the Pirates lineup. Four of them were under .300. One player who might have made a difference for them is Rajai Davis, who now toils in San Francisco. The Giants were smart enough to install him as a leadoff man, and he's rewarded San Francisco with a .417 OBA. The player has no power, but the Giants concentrated on what he can do. What he does is get on base, something the Pirates needed more than an old starting pitcher. David reached base three times in six plate appearances last night, scoring the first run for the Giants after a leadoff walk, and getting hit by a pitch in the thirteenth to put the winning run at third. The Giants took the game 3-2.
