There are Opening Day game-used baseballs galore, perfect for commemorating that first trip you might have taken to the ballpark last spring. The Cabrera ball was thrown by Twins reliever Casey Fien in the top of the seventh at Minnesota, in the dirt. Fien struck out the side that inning, Cabrera his last victim -- but, obviously, the Tigers slugger recovered from that 0-for-5 debut pretty well.
It was the year when the Major League Baseball All-Star Game returned to New York, hosted by the Mets, and you can bid now on the actual third base used from the sixth and seventh innings on July 16 at Citi Field. David Wright of the Mets and Manny Machado of the Orioles played third during those two scoreless innings.
During All-Star Week, fans saw Apples on Parade positioned throughout the Big Apple for the festivities. That included one that was signed by all the National League All-Stars as they got into ballpark-bound parade trucks for the All-Star Game Red Carpet Show presented by Chevrolet. Your friends won't have this.
Roy Halladay threw the last pitch of his career in 2013, and you can bid on a ball used in his 200th-win game. Halladay threw the ball to Placido Polanco on April 14 at Miami. Halladay allowed only one run over eight innings in recording his first win of the season that day, and he went on to win three more games before announcing his retirement with a 203-105 record.
Michael Wacha finished the season as a big topic of conversation, going on to a 5-1 postseason record for the Cardinals, and you can bid on a ball used in his MLB debut against Kansas City. Or how about a ball thrown by Wacha to Dodgers rookie Yasiel Puig during the NL Championship Series?
There are many more like this, and any of these items can be a perfect way to remember a season that led to a Red Sox World Series championship. Koji Uehara threw the last pitch of the season, and you can even find a ball he pitched to Prince Fielder in the postseason.
