Mark Derosa has attributed much of his success to Rudy Jaramillo! In 2003 and 2004 Mark Derosa's career looked to be going down hill, after two dismal seasons at the plate putting up back to back years of sub .700 ops. Derosa's batting line in 2003 .263/.316/.383/.699, in 2004 .239/.293/.320/.614 not very inspiring to say the least! In 2005 he joined the Texas Rangers and Rudy Jaramillo started working with him, Derosa's line in 2005 .243/.325/.439/.764. Better but certainly not optimal, notice though his slugging % and Obp rose significantly. In 2006 Mark's second year with Jaramillo, Derosa turned the corner .296/.357/.456/.812!
Marlon Byrd had back to back dismal seasons as well in 2005 and 2006 putting up sub .700 ops. Line for 2005 .264/.318/.380/.698 in 2006 .223/.317/.350/.667 simply terrible! In 2007 Byrd joined the Rangers and hitting coach Rudy Jaramillo set to work, Byrd in 2007 .307/.355/.459/.814, in 2008 .293/.380/.462/.842, in 2009 .283/.329/.479/.808. Byrd saw almost immediate substantial improvement.
Baker has shown some pop in his bat, yet has been inconsistent over his career, what impact will Jaramillo have on a player like Jeff Baker? I think he can be a very solid everyday second baseman, if he is a quick study under Jaramillo. Mark Derosa was 30 when Jaramillo got his hands on him, Baker will be 29 in June. Mark Derosa is 6 foot 1 205 pounds, Jeff Baker is 6 foot 2 210 pounds! I am just saying Baker has very solid potential and is in his prime right now, I think the cubs will be fine with him starting at second base. What do you think?
