It might be a good time to invest in some Tim Anderson rookie cards. A web site devoted to such things reveals that the average price of a rookie card of the former East Central Community College standout is $4.96. But one card, a “2013 Leaf Draft Superfractor RC Rookie Auto Autograph 1/1,” sold for $58 in January of 2015. Anderson hasn’t played a big league game yet. He was sent down to Triple-A Charlotte by the Chicago White Sox on Thursday, but it won’t be long before the highly rated prospect assumes the shortstop job at Comiskey Park. Could be this summer. A first-round pick (17th overall) out of ECCC in 2013, Anderson put up some great numbers at Double-A Birmingham in 2015: .312, 12 triples, 49 steals, 79 runs and 46 RBIs in 125 games. Some might remember that he homered at Trustmark Park in Pearl in his first Southern League game back in 2014. He has been in the White Sox’s big league spring camp the last two years and made an impression. “The biggest thing for me seeing him in the last couple years is, defensively, he just looks so much better and confident,” ChiSox manager Robin Ventura told mlb.com. Buy low, they say. Might be a good time to load up on some Tim Anderson rookies.
