Mark Teahen down, Dallas McPherson up

whitesox.com:

Prior to tonight’s game vs. Texas, the Chicago White Sox placed infielder Mark Teahen on the 15-day disabled list (retroactive to May 12) with a strained right oblique and purchased the contract of infielder Dallas McPherson from Class AAA Charlotte. … McPherson, who will wear uniform No. 45, was signed by the Sox as a free agent on November 10, 2010. The White Sox 40-man roster is at 36.

McPherson is hitting .305/.366/.458/.824 with 39 K and 12 BB, a .361 wOBA and a .435 BABIP. Clay Davenport says his EQA (Equivalent Average) is .291 and McPherson’s Major League EQA is .229.

UPDATE: And McPherson singles on his first White Sox at-bat! Bring him in boys!

BP about Equivalent Average:

A measure of total offensive value per out, with corrections for league offensive level, home park, and team pitching. EQA considers batting as well as baserunning, but not the value of a position player’s defense. The EqA adjusted for all-time also has a correction for league difficulty. The scale is deliberately set to approximate that of batting average. League average EqA is always equal to .260.

Dayan Viciedo wasn’t the one that got the call because: 1: he’s more of an outfielder, 2. he wouldn’t get regular ABs like in AAA.

Well , he wasn’t getting enough ABs last year in the Majors but that didn’t stop the Sox from calling him up.
