In the third installment of MLB.com’s seven-part Spring Training preview, we take a look at some of those White Sox prospects who could help the team in the future.

The Yankees and left-handed closer Aroldis Chapman agreed to a one-year contract worth $11,325,000 Friday, avoiding arbitration.

The true measure of any relationship.

The nice days in Denver mean overnights for Mike Craig, the National Hockey League’s senior manager of facilities operations.

With a wealth of pitchers set to be in camp this spring, the Indians added another layer of catching depth to help handle the workload. On Friday, Cleveland signed veteran catcher Guillermo Quiroz to a Minor League contract, which includes an invitation to attend Spring Training with the big league club.

The Indians already stood to have a tight bullpen race this spring. Cleveland just made the competition for relief jobs a little more interesting with the signing of right-hander Tommy Hunter to a one-year, $2 million contract.

As numerous record-breaking deals were handed out to free agents this offseason, speculation quickly shifted to Bryce Harper’s possible free agency after the 2018 season. More specifically, how much money could Harper, the reigning National League Most Valuable Player, potentially earn if he reaches free agency at the prime age of 26?

Spring Training gets underway in a week, and ideally the Marlins would like to add another pitcher or two before pitchers and catchers take the field on Feb. 19. But the signings have to make sense, and the club is willing to wait, even if it means reaching agreements after practices begin.

The Astros held a season preview luncheon for the media Friday at Minute Maid Park that would have made the local optimist club envious.

Major League Baseball on Friday issued Mets reliever Jenrry Mejia a lifetime suspension after he tested positive a third time for a performance-enhancing substance.

The first official report dates are about a week away, but the first reports are already emanating out of Spring Training camps. On Friday, for example, Masahiro Tanaka told reporters that he “can’t really say” whether he’ll be ready for Opening Day until his progression from offseason elbow surgery involves throwing off a mound.

Major League Baseball and the Major League Baseball Players Association have collaborated on a new design for protective headgear that will be unveiled this spring.

The bullpen must improve. It was below average during the second half of the season last year. Yes, the Nats revamped the relief corps by adding Shawn Kelley, Trevor Gott and Yusmeiro Petit, but we will not know how much they help until the season starts.

Twins first baseman Joe Mauer told the St. Paul Pioneer Press that his vision has been affected by the concussion that ended his 2013 season, especially during day games, as the sun makes it tough for him to pick up the ball. Mauer’s offensive production has declined the past two seasons.

Malvina Singer is amazingly stoic, grieving the sudden loss of her husband of nearly 43 years, Tom, our 15-year colleague at MLB.com, at 67. It has been a whirlwind of shock for the family, fortunately a far-reaching, faithful, highly supportive and positive group.

The Phillies could pack their Spring Training truck blindfolded at this point. But they made things easier on themselves Friday morning, when they loaded the truck for its annual 1,058-mile trek from Citizens Bank Park to Bright House Field in Clearwater, Fla.

Fenway Park was home to a different type of world-class athlete Thursday evening.
