One of the old axioms is that a player must have power, or the threat of power in order to draw a large number of walks. In 2009, Russell Martin is trying to show a man can walk when he is able to. After playing in his 85th game, Martin's triple slash numbers are .262/375/.315, in 357 PAs, good for a 85 OPS+, among all hitters in the NL, but also good enough for a 100 OPS+ among catchers.
Obviously the big worry about Martin is his declining power, and the lack of power he has today. Of Martin's 79 hits, only 10 are doubles, and 2 are home runs. Yet, he still leads the Dodgers in walks and is on pace to near his career walk total established last year.
Obviously, we all want Martin to slug more. He was considered to be one of the better offensive catchers when he came up. But as he currently, he's still considered to be worth 1.5 WAR to date.
Will Martin ever regain his power stroke? Who knows, but if he doesn't, he is still a valuable catcher in his own right.
(But hopefully he will one day, right?)
