Went down to the concourse to grab some dinner in the bottom of the first and heard one of the Arizona radio guys — not sure which one — say “Brett Tomko has always struck me as a guy whose talent far exceeds his won-lost record in the major leagues.” That, of course, is a fancy way of saying he’s an underachiever — something that is very much in evidence tonight. Tomko already has walked four batters in three-plus innings, his body language is suspect, and he just picked up a tapper by Chris Snyder and threw it up the rightfield line, allowing Chris Young to score from first to cut the Dodgers lead to one run. Oh wait, he just gave up an RBI single to opposing pitcher Micah Owings to tie the game. It was Owings’ first major-league hit, but not his first ML RBI. He got that two innings ago, when he hit a sac fly, also to tie the game. Dodgers 3, D-backs 3, bottom 4.
