All three players also receive invitations to big league spring training.
Peterson is an interesting signing. A former 49th-round pick back in 2002, he appeared in 23 games with the Cardinals in 2013, his first taste of the big leagues at age 29. He went 2-for-26 (.077) with two RBIs, two walks and 11 strikeouts.
Peterson, now 30, put up a monster season at Triple-A Memphis, however, hitting 25 home runs, driving in 86 and posting a strong .296/.364/.531 slash line.
I had previously reported Delcarmen's signing. The former Red Sox righty last appeared in the majors in 2010, posting a 4.99 ERA and 1.471 WHIP in 57 games. He helped lead Boston to a World Series title in 2007.
Last season, Delcarmen put up a 2.83 ERA and 46 strikeouts in 54 innings at Triple-A Norfolk, the Orioles' Triple-A affiliate.
Jeroloman batted .228/.333/.278 as part of three minor league teams (Pittsburgh's Triple-A affiliate in Indianapolis, Triple-A Syracuse and Double-A Harrisburg).
He was hospitalized for multiple days after a vicious home plate collision during the playoffs while playing with Harrisburg. He joined the Nationals' organization last year after being traded from the Pirates during the season.
Update: Major League Baseball announced that more than $120,000 was raised for StandUp2Cancer through its online auction of unique baseball experiences and items.
The top money-raising item was having Bryce Harper and Anthony Rendon visit a child's school for lunch. That item raised $9,126.
A tremendous cause, and a tremendous amount of support by some baseball fans out there.
