I too have been critical of Justin Smoak ... lets face it the Mariners are a young club and are no threat to the league right now. So lets allow the young players some room and time to develop. That includes Smoak.
Smoak's percentage of fly balls may just be an indicator he is not suited for Safeco. Beltre drove me crazy while he was here, loved the man but he was not suited for Safeco. I think Safeco gets into hitters head after a time and they press too much. Visiting hitters can come into Safeco with a decent swing and mental attitude (from playing elsewhere) and hit okay ... but the Mariners are here 50% of their games and I think the place gets into their heads.
Move the fences in? Could be what they have to do. I'll be interested in seeing what the Ms do during the offseason ... I bet the fences come in. But that won't solve the problem of line drives hanging in the air just long enough for speedy outfielders to track them down. Safeco will always be a tough place for line drive hitters (Ackley), the heavy air seems to transform doubles into fly ball outs.
Moving the fences in would favor power hitters over line-drive hitters, thus Smoak (with the fences in) could be a good fit.
Play out the year, let the young guys play and develop, get ready for Hultzen, Paxton and Walker. Hopefully it will all come together in 2013 (fences in) and 2014.
