Here are today's minor transactions, with the newest moves at the top of the page…

• The Rangers have purchased the contract of first baseman Chris McGuiness from Triple-A Round Rock and created a spot for him on the 40-man roster by moving Colby Lewis to the 60-day DL, according to a team press release.  McGuiness will fill in for Mitch Moreland, who was put on the 15-day DL in a corresponding move.  The 25-year-old McGuiness is a left-handed hitter who was acquired by Texas from Boston as part of the Jarrod Saltalamacchia trade in 2010.  McGuiness has an .858 OPS at Triple-A this season.
• The White Sox have purchased the contract of right-hander Ramon Troncoso from Triple-A Charlotte, the team announced.  Troncoso, 30, signed a minor league deal with Chicago in January after spending all of 2012 with the Dodgers' Triple-A affiliate.  Troncoso posted a 3.92 ERA, 2.07 K/BB and 6.4 K/9 in 197 1/3 IP out of the Dodgers' bullpen from 2008-11.  In corresponding moves, the Sox also recalled righty Deunte Heath from Triple-A, optioned Brian Omogrosso to Triple-A and placed Jake Peavy on the 15-day disabled list.
