Josh Hamilton, who has publicly battled addictions to alcohol and drugs, admitted to having a relapse on Monday.
The Dallas Morning News reported that sources told the paper that Hamilton was drinking at Sherlock's Pub in Dallas on Monday night and that teammate Ian Kinsler showed up to attempt to convince the slugger to return to his home in Westlake.
Hamilton and the Rangers scheduled a press conference for 1 p.m. Friday afternoon at Rangers Ballpark in Arlington to comment more on the situation.
"We are aware of a situation but have no further comment at this time," the Rangers told NBC 5 in a statement Thursday night.
On Friday, Hamilton's wife Tweeted the following: "“Truly appreciate all the encouraging & supportive tweets we've been getting. God is Faithful and forgives- so thankful that you all are showing us such love and encouragement during this time.”
Former assistant hitting coach Johnny Narron, who left for the Milwaukee Brewers in the off-season, used to help keep Hamilton on the straight and narrow.
A few weeks ago, Hamilton's father-in-law turned down the position. At the time, he said that he didn't think Hamilton needed an accountability partner.
Hamilton also said he felt he was fine.
Hamilton has had an on-going struggle with addiction, including a relapse in 2009. In August 2009, Deadspin.com published photos of Hamilton drinking and cavorting with several women at a bar in Tempe, Ariz., that January.
Prior to that episode, Hamilton said hadn't had a drink since Oct. 6, 2005.
Hamilton created headlines in 2008 with his inspired comeback from the depths of alcoholism and drug abuse to lead the major leagues in RBIs and nearly win the Home Run Derby.
When the Rangers acquired the 28-year-old outfielder from the Cincinnati Reds on Dec. 21, 2007, they were aware of Hamilton's off-the-field problems and came out with a "zero tolerance" policy regarding his drinking.
NBC 5's Lita Beck, Frank Heinz, Greg Janda and Amanda Guerra contributed to this report.
