Here's another interesting player comparison. Take a look at these minor league numbers of two slugging first basemen:
Player A: 48 G / 171 AB / 10 HR / 28 RBI / .316 BA / .994 OPS
Player B: 41 G / 133 AB / 5 HR / 30 RBI / .316 BA / .962 OPS
Player A is Mark Teixeira and the numbers are from when he was a 22-year old at AA Tulsa.
Player B is Red Sox prospect Lars Anderson and the numbers are from last year at AA Portland. Anderson will be 22-years old next year. Here's something to note from the linked page:
Upside potential: All-Star-caliber first baseman that will contend for batting titles and RBI crowns, with plenty of homers to boot.That's a description of Mark Teixeira. And that description of Lars Anderson is perhaps the main reason why the Red Sox won't be signing Mark Teixeira.
