Baseball & 5" x 6" photo both personally signed by Minnesota Twins #19, 3rd baseman Danny Valencia.

Valencia made his major league debut with the Twins in June 2010. He was named the third baseman on Baseball America's 2010 All-Rookie Team, and on the 2010 Topps Major League Rookie All-Star Team. In 2011, he led the Twins in RBIs, and led all major league third basemen in assists.

On June 3, 2010, Valencia was called up to replace Michael Cuddyer. On July 26, he hit a grand slam off reigning AL Cy Young winner Zach Greinke to record his first big league homer. The feat marked the first time in the 49 years of Twins franchise history that a player's first Major League home run was a grand slam. The game was also his first 4-hit performance. The next day, Valencia became the first Twins rookie to have back-to-back games with 4 hits apiece.

In 2010, Valencia hit .394 with runners in scoring position. That was best in the AL (ahead of Josh Hamilton), among those with at least 75 plate appearances in that situation. On defense, he had the 5th-best fielding percentage among AL third basemen (.973).

For the 2010 season, his .311 batting average (the best by a Twins rookie in 46 years), .448 slugging percentage, and .799 OPS were the highest among AL rookies with 300 or more plate appearances. He came in 3rd among AL rookies in hits (93) and total bases (134). In 65 games after the All Star break, he led AL rookies in batting (.311), RBIs (37), and doubles (16).

In 2011, Valencia batted .246, with 15 home runs and a team-leading 72 RBIs. On defense, he led the all major league third basemen in assists, with 260.
