The next baserunner that Philip Humber allows will be his first in quite some time.
Humber retired all 27 Seattle Mariners he faced in his last start on Saturday, pitching the 21st perfect game in major league history.
On Thursday, against the Red Sox, he will try to replicate that feat, and chase history again by attempting to become the second pitcher ever to throw two consecutive no-hitters.
The only man to ever pull that off was Johnny Vander Meer, who did so in 1938 against the Boston Bees and then the Brooklyn Dodgers four days later. Humber, on the other hand, will likely have a more difficult task facing the Red Sox on Thursday than against the sometimes-hapless Mariners squad.
However, Vander Meer's feat is far from the only one in baseball lore that may never be touched again. Many of baseball's records have stood the test of time
Ted Williams was the last player to bat .400 in a season, a feat that hasn't been matched in over 60 years. That same year, Joe DiMaggio recorded a hit in 56 straight games, a streak has stood alone since then as well. More recently, we have seen Barry Bonds smash 73 home runs in a single season and Cal Ripken's "Iron Man" streak of consecutive games played stand at 2,632.
Baseball is a game of numbers and a game full of history. When taking a look at some of the sport's most famous numbers, however, which feat seems most attainable for today's player?
