Outfielder Yoenis Cespedes has made quite an impression on Red Sox Nation since he was acquired nearly a month ago for ace Jon Lester.

On Saturday afternoon, he continued to add to his resume.

With just over three quarters of the MLB season complete, it is a good time to take a look at some records that are on the verge of being broken during the rest of the 2014 campaign.

True, the marks we are going to discuss don’t necessarily carry legendary weight. No one is on the precipice of breaking Barry Bonds’ single-season home run record, for example, or of topping the 233 strikeouts Mark Reynolds amassed in 2009.

These will be a bit more obscure.

The 2013 playoff races were defined by strong rookie performances.

There was Michael Wacha, who went from first-round draft pick in 2012 to No. 2 starter for the St. Louis Cardinals down the stretch and well into the postseason. Gerrit Cole and Sonny Gray had similar impacts on their respective teams, as both right-handers reached the major leagues in the middle of the season and ultimately shined in their first tastes of playoff baseball.

Charlie Hustle, for 25 years now, has been waiting for a second chance that continues to outsprint him.

When is a lifetime ban long enough?

A smart string of September call-ups can often be the difference between a playoff berth and a phone call to the local golf course.

When MLB rosters expand to 40 on September 1, expect some of the game's top youngsters to get the call to the majors. The New York Yankees will certainly make some additions, but who will be brought up to help the team's run at the American League Wild Card?
