Morneau had surgery on that wrist last September to stabilize a tendon and was in a cast for six weeks during the offseason.
He said it started bothering him again during the club's three-game series in Tampa from April 20-22 and that he began to feel more discomfort as the week went on. He said it was particularly painful in his second at-bat against Angels left-hander C.J. Wilson in the fourth inning of Monday's 4-3 loss, when he struck out swinging.
"It was one of those things I was able to deal with but then it kind of got worse over the weekend," Morneau said. "I don't know. There's not much I can do. Hopefully it's just scar tissue breaking up."
Morneau said he's not sure if he'll have an MRI exam taken on his left wrist during his meeting with Varecka. He added the ligament doesn't feel loose, but that his wrist feels more sore than anything.
"I'm not going to play worst-case scenario yet," Morneau said. "I'm going to try to stay positive and hopefully it's just a normal part of the process and will just be a couple days and maybe needs a cortisone shot or maybe some rest. Hopefully it's just scar tissue breaking up. So I'll stay optimistic now until I hear different."
Morneau grounded out to first base and struck out in his two at-bats against Wilson. Sean Burroughs went 0-for-2 as his replacement, as he grounded out to lead off the seventh and grounded out again with two runners on and one out in the eighth against reliever LaTroy Hawkins.
Morneau, 30, played in just 69 games last season after battling concussion symptoms and undergoing surgeries on his neck, left wrist, left knee and right foot.
He's batting .230 with a .313 on-base percentage and .459 slugging percentage in 20 games this season. He also has four homers, five doubles and nine RBIs while seeing action in 16 games as designated hitter and four games at first base.
