• The Rangers have assigned third baseman Mike Olt to Double-A Frisco, and expect him to be activated on Friday night. He has not played in a game since April 25 because of vision problems that have been addressed with eye drops and medication.
Olt was hitting .139 with one home run and six RBIs at Triple-A Round Rock before going on the disabled list. In 72 at-bats, he struck out 32 times. He has spent the past week working out at the Rangers training facility in Arizona. He is the Rangers' second-ranked prospect.
• The Red Sox's rotation is uncertain for their three-game series against Texas that starts Tuesday at Fenway Park. Boston is undecided because Clay Buchholz keeps getting pushed back because of an AC joint injury. But the Rangers will likely see John Lackey on Tuesday and Jon Lester either Wednesday or Thursday.
• Triple-A Round Rock and Double-A Frisco were also rained out on Wednesday.
• Because of Wednesday's rainout, Texas lost a half-game in the standings to Oakland. That's the fourth straight day the Rangers have lost ground, something that hasn't happened since May 26-29, 2010.
