Question: What age was Pastornicky's replacement in 2012? Passage:Following the conclusion of the 2011 season, Braves general manager Frank Wren highlighted several important areas to improve during the offseason. Since most players were committed contractually to the team in 2012, Wren acknowledged that he would likely make few major changes. One spot that was mentioned for a major overhaul was the shortstop position, where Alex Gonzalez had played since the Yunel Escobar trade with Toronto in July 2010. Gonzalez entered the offseason as a free agent and proved too expensive for the team. Wren ultimately allowed prospect Tyler Pastornicky the starting duties in 2012, until he was replaced by Andrelton Simmons in mid-June. When Simmons was hurt in July, Jack Wilson, Paul Janish, and Martin Prado filled in for him. While center fielder Michael Bourn returned to his position in 2012, Wren also suggested that the corner outfield positions were areas of contention. In 2011, the Atlanta outfielders finished the season last in the National League in on-base plus slugging and slugging percentage. Wren stated that right fielder Jason Heyward and left fielder Martin Prado had no guarantee of getting the starting jobs in 2012. On the day after the Braves were eliminated from the playoffs in 2011, Wren said that veteran starter Derek Lowe was unlikely to have a spot in the starting rotation in 2012, due his poor performance in 2011 and a plethora of rookie pitching talent in the Braves farm system. With Lowe guaranteed $15 million in 2012, Wren projected that any of Lowe's salary picked up by another team would significantly assist his efforts to find a shortstop or outfielder. By the end of October, Lowe was traded to the Indians.
