Input: Consider Input: Question: How old was the person traded to the Oakland Athletics when the trade occurred? Passage:Although in 2008 Baseball America projected Venable as an every day starter for the Padres in 2010, some experts questioned whether he would be a long-term solution in center field for the team. Venable started the 2009 season with the Padres' Triple-A affiliate, Portland Beavers, but he was recalled by the Padres on June 3. His father, Max, served as the Beavers' hitting coach in 2009. Following the July 5 trade of Scott Hairston to the Oakland Athletics, Venable shared right field with Kyle Blanks. On July 12 against the San Francisco Giants, he had his first home run of the season in his first career four-hit game. Between July 30 and August 5, he homered in five of seven games. In an August 23 game against the St. Louis Cardinals, he was involved in a bench-clearing incident when Albert Pujols thought he threw an elbow while being tagged out. In 2009, he posted 12 home runs and tallied 38 runs batted in (RBI), while defensively 493.2 of his 643 innings were spent in right field and only 117 in center field.
