There are, most baseball aficionados agree, eight different ways to reach first base. In the crazy top of the fifth inning on Thursday night, the Chicago Cubs produced five of them – in a row — and went on to a 9-8 victory over Washington that sent them to the National League Championship Series. With two outs in the fifth, down 4-3, the Cubs did this: three straight hits (infield hit, single, double), intentional walk, dropped third strike (albeit controversial), catcher’s interference and hit batsman. All that was missing in the four-run inning was an error, a fielder’s choice and fielder’s obstruction. For the record, former Mississippi Braves Jason Heyward (the intentional walk) and Tommy LaStella (the catcher’s interference) were involved in the madness. P.S. Austin Riley, the ex-DeSoto Central High star and Atlanta prospect, went 3-for-5 with a home run (off Madison Central alum Spencer Turnbull) and four RBIs to pace Peoria to a 10-6 win against Mesa on Thursday in the Arizona Fall League. Turnbull, a Detroit prospect, worked 2 1/3 innings, yielding eight hits, a walk and seven runs (four earned) to take the loss.
