From rotohardball.com comes a well done report that desvribes Marcum's change as bar far the most effective in baseball....... Let's look at just how good Marcum's 2010 season was. Here's his roto line: 13 W, 3.64 ERA, 165 K, 1.15 WHIP, 0 SV. Looking deeper, he pitched the most innings of his career (195.1) and had the highest K/9 (7.60) and lowest BB/9 (1.98) of his career which resulted in the 6th best K/BB% in the majors. Marcum's career whip is only 1.24 thanks to his consistent ability to limit walks and maintain a low batting average against (.247 career and in 2010). He's probably always going to give up 20+ homers a season in the homer-friendly Rogers Centre though many are solo shots thanks to this ability to limit baserunners. Both his career BABIP (.280) and LOB% (77.4%) are above average and if he can improve even more with his K/9 and BB/9 those numbers may only get better. Looking at BIS pitch/fx data via Fangraphs, Marcum abandoned his slider completely, throwing more fastballs and cutters to set up his devastating change-up. His change-up resulted in a swinging strike a whopping 28.1% of the time, resting at about 80-81 mph, or about 6 mph slower than his 86-87 mph fastball. According to Fangraphs, his change ranked top in the league in wCH at about 26 runs above average. That's over 5 points higher than the second best, Felix Hernandez's 18.7. The improvements Shaun Marcum made in 2010 after missing over a year, coupled with his dominance in the first half of 2008 make me a serious believer that lands him within top 25 SP territory for me. Some may be weary, and some may even take fellow pitching standouts Ricky Romero and Brandon Morrow first, especially in keeper leagues. Toronto has a wealth of useful pitching and Marcum does have two years left of arbitration which increases his trade value. If Toronto does resign him, he should be considered their ace. The question remains: Will he be drafted like it?
