So let's pretend we get Renteria or A-Rod to play short? Why is everyone so quick to assume DeRosa is automatically the starter at second base over Theriot. They both have a career OBP of .341, Riot does have a 29 point lower slg of .379 compared to DeRosa's .408, I'd say they are about the same when it comes to batting, with a slight edge to DeRo. So another tool we can use to value them is baserunning, and yes it is relevant. Riot stole 28 bases and was caught 4 times in '07, good for a 87%. DeRo stole one base and was caught twice good for 33%. over their career, Riot has a 87 percent success rate compared to DeRosa's 48 percent. We've now concluded that Riot is considerably faster and better at stealing base than DeRosa and that DeRosa is a slightly better batter. Next tool I can think of is fielding, Riot has a career FP of .992 percent at 2B compared to DeRosa's .984 percent. We've now concluded that Theriot is a better fielder and baserunner than DeRosa but slightly weaker batter. Let's not forget that DeRosa is on the wrong side of 30 and likely to decrease while Theriot is 27 going on 28 and should improve or stay the same. Based on the evidence, and if we get a new SS, I'd say we'd go into ST in a fair battle between DeRosa and Riot with the better performer getting the nod and without experience or past performance being considered. Ideas?
