Ruben Tejada: In 25 at bats, he is hitting .320 with eight hits (five doubles) and four walks for an on-base percentage of .414. He has stolen zero bases and made no errors in the field.
Jose Reyes: In 33 at bats, he is hitting .242 with eight hits (two doublts & one triple) and two walks for an on-base percentage of .286. He has stolen three bases and made three errors in the field.
There aren't many surprises away from the plate. Many thought Tejada would be a defensive upgrade over the flashy Reyes and on one expected Tejada to keep up with Jose on the base paths. However, so far (and I stress a small sample size here), Tejada has more than held his own against the much more high profile Reyes. Many have commented that they're impressed with Tejada's approach at the plate this season, and the early numbers warrant that praise.
When you factor in the fact that Tejada will make only $491k versus Reyes' $10 million it only aids the case for Tejada, thus far. We'll be sure to keep an eye on this as I expect the numbers to get much tighter and/or shift in Reyes favor as the season progresses.
