The Cardinals' Rick Ankiel, the pitcher-turned-outfielder, has been having a hot July, batting .349 with 5 HR (20 overall) & 12 RBI (50 overall). For the year, he's averaging 1 homer for every 15.35 AB, which is more frequent than teammate Albert Pujols (1 every 15.89) & AL HR leader Grady Sizemore (1 every 15.74).
Ankiel's 99 Ultimate Victory RC started the season on fire averaging $37.04 in April. As his performance cooled, so did his values. His UV RC then dropped to an average of $18.53 in May, and $15.54 in June. I haven't seen any sell this month yet, but I expect them to be on the rise. His most popular autograph card, his 00 SPx Auto #'d 1500, is selling in the $40-50 TAC range so far in July. You can probably find his 99 SP Top Prospects Auto for around $20.
Has anyone been tracking Ian Kinsler? I've been watching him since July '07, and all I can say is WOW! He's batting .337 with 14 HR, 58 RBI & 23 SB, he's in the middle of a 25 game hit streak, and he's been selected to his first All-Star Game. Only downside? His Rangers are 7.5 games behind a pretty tough AL West-leading Angels team.
Expect to pay in the $15-25 TAC range for his 05 Bowman Chrome Ref RC.
