Martin Peguero signed as Esteilon, and did so under some strange circumstances, though they didn’t appear to be age-related. Peguero isn’t that much different that Carlos Triunfel was before injuries and stalled development derailed his prospect status. Peguero has a ton of offensive potential, and like Triunfel there is a likelihood that he will have to move off of shortstop. Presently it appears that second base will be his best option, which would limit his value since the Mariners are hoping Dustin Ackley holds down the position for the next decade or so, but so much can happen between now and Peguero’s big league debut that his position isn’t presently-damning. Peguero has projectable offensive skills, and he wasn’t terrible at 17 playing in a league full of 20 year olds (.103 ISO, 83 wRC+). The rookie leagues though, are really disproportionately old, as they are frequently filled with a bunch of college-level draftees. Peguero’s minor league level in 2012 will make a pretty big declaration about what the organization thinks of him. He seems likely to be promoted to one of the A ball ranks, and if he makes it to High Desert by the end of the year it will probably be because he had a pretty good year.
