For those of you who like bringing up pitchers quickly when they are young after they have had a drop of success and let them learn at the majors, please look at the quotes below from McCatty about Balester. Basically, the early promotion last year cost him about a year due to screwed up mechanics. My guess is that the Nats will wait to call Balester up until Detwiler or Zimmermann struggles enough that management decides to send one down for the AAA season JZ/RD should be having at this age.
"Balester's struggles began last season when he made his major-league debut with Washington on July 8 at the age of 21. He started 15 games for the Nationals in 2008, going 3-7 with a 5.51 earned run average.
"When he went up to the majors, some observers compared Balester to Tom Seaver, whose powerful drop-and-drive technique resulted in a trademark dirt mark on his knee. Balester emulated Seaver's motion, but in doing so, Balester threw his pitching mechanics out of whack.
"'When he went up last year a lot of people called him a drop and drive pitcher,' McCatty said. 'There's not a whole lot of drop and drive pitchers in the big leagues. There are some, but not many.
"'Bally's 6-foot-6 and by dropping so low down, I told him he was pitching like he's 4-foot-4.'
"Balester struggled to find his natural motion in spring training. "
