Also, consider the fact that it was his first full season back from Tommy John surgery. In 2009, he tossed just 15.2 innings. So, we should have expected Marcum to probably hit a bit of a wall in 2010 at some point, right? In his first 125 innings, he had a 3.24 ERA. And, sure enough, over the final two months of the season he had a 4.35 ERA, though even that's not bad considering his schedule. (Yankees, Boston x3, Tampa x2, Rangers) That is concerning to me. How much damage if any was done by pitching him that many innings when he experienced a obvious decline in effectiveness?
