Minor League Transactions: Feb. 20-26 (VIDEO)

Official minor league transactions, conveyed to Baseball America by Major League Baseball, for the period Feb. 20-26.

Arizona Diamondbacks
Placed on voluntarily retired list: C Joel Thys, OF Todd Glaesmann

An exceedingly light of installment of Minor League Transactions—the lightest ever?—still contains a bit of player-development news. Todd Glaesmann, a 23-year-old corner outfielder who appeared in the 2013 Prospect Handbook, has decided to retire rather than head to spring training with the Diamondbacks. He joined the Arizona organization last December as the player to be named in the three-team trade that landed Heath Bell and Ryan Hanigan with the Rays, prospect southpaw David Holmberg with the Reds and righty Justin Choate with the D-backs.

Glaesmann, who signed with the Rays for $930,000 as a third-round pick out of high school in 2009, spent last season at Double-A Montgomery, batting .240/.289/.378 with 11 homers in 132 games. Noted for a strong throwing arm and plus raw power, he peaked at No. 16 on Tampa Bay’s prospect list heading into 2010. With a .257 average and .308 on-base percentage in full-season ball, however, his batting approach required improvement to unlock his power more frequently.

"There is a learning curve mentally (and) 2012 gave me a lot of confidence," Glaesmann told correspondent Jack Magruder this offseason. "Numbers-wise, (2013) was not the year I wanted. Sometimes I think people get caught up in numbers. I take it as a learning experience."
