Two ball players, who've been remarkably hot for long periods this season are Joey Votto of the Cincinnati Reds and Jose Altuve of the Houston Astros. Yes, I've read Bill James and know hot streaks aren't real, but I like pretending.
Votto has always engendered controversy over his refusal to swing at pitches outside the strike zone, regardless of circumstances (see Skynet Is Activated), but consistently hit for high average, on-base and slugging percentages.
(Votto, not swinging, zimbio)
This year he seemed to make the argument moot. Joey was horrible for the first 50 games, hitting only .207 on May 29, with an on base percentage (OBP) of .330, and slugging a miserable .367. This was coupled with an erosion in his control of the strike zone. In his last two full seasons, Joey walked in 20% of his plate appearances (PA) and struck out in 19%. As of May 29, he'd walked in only 14% of his PA and was striking out 27% of the time.
But in the 69 games since then, Votto has played like a alien visitor from another galaxy with superhuman capabilities, hitting .378, with an OPB of .507 (that's Ted Williams, Babe Ruth territory), and slugging .622, raising his season average to .307, and his stats now look like a normal Joey Votto year. During this run, he's been walking in 21% of his PA and striking out in 17%.
(Altuve, from espn grantland)
Jose Altuve, the diminutive second baseman for the 'Stros, has played well since the beginning of the season. On May 27, he was hitting .311, and an OPS of .939, with more power and walks than he'd had in prior years.
And then he got really hot. Over his last 73 games, Altuve's batting .402 (raising his average to .366), with an OPS of 1.042, and propelled himself into the American League MVP discussion.
It'd be fun to see both of them continue at this pace until the end of the season.
