Manny Ramirez had a slow start in '08, batting .256 with 1 HR & 8 RBI through 4/11. During those first two weeks of the season, his 92 Bowman RC was averaging $12.20 TAC. Since then, he's been lighting it up at the plate, now with a .356 BA and 6 HR & 20 RBI. That same Bowman rookie is now averaging around $17.99.
Through 4/6, Rick Ankiel was batting .348 with 3 HR & 6 RBI, and his 99 Ultimate Victory RC was selling in the $40-56 TAC range. It was all downhill from there, with his BA plummeting to it's current .244, with just 4 HR & 11 RBI total so far for the season. His UV rookie has also been falling, first down to the $30's last week, and now into the $20's this week.
The Yankees' Phil Hughes was commanding top $ this past off-season, but has not been able to find his groove through his first 4 starts. His first outing was decent, posting a 3.00 ERA and a no decision. He then proceeded to lose his next 3 starts, and his ERA has risen to 8.82! All of his key Auto rookie cards have experienced drops in value as a result. His 05 Bowman Chrome Auto RC fell from around $112 TAC at the beginning of the month down to the mid $80's range. His BC Ref Auto RC dropped from the high $140's down to the low $130's, and his BC X-Fractor Auto RC dropped from around $280 down to around $250.
Johan Santana was a super hot commodity when he got traded to the Mets. Last month, his 00 Bowman's Best RC #'d 2999 averaged $76.57 TAC, and his 00 Finest RC #'d 3000 avearged $136.76. Through his first 4 starts, he's posted a disappointing 2-2 record & 3.12 ERA (hobby expectation was much higher, with a lot of anticipated value already built into his pricing). Both of key rookies have dropped off quite a bit in April, with his BB RC averaging $65.75 (last sale $46.88 on 4/20) & Finest RC averaging $114.10 (last sale $99.65 on 4/20).
Felix Hernandez started the season with a 0.00 ERA in this first two starts, but received no decisions in both due to disappointing reliever performances. He finally got his first win in his 3rd start, and is now 2-0 with a 1.67 ERA after 5 starts. His 04 Bowman Chrome Auto RC was selling for around $105 TAC in early April, and has since risen to around $115. His BC X-fractor Auto RC was at around $220, and is up to around $230 now.
