Orioles designated hitter Jim Thome is headed back to Baltimore to have tests on his sore neck.

Thome said Monday, before the Orioles played the New York Yankees, that he will have an MRI on Tuesday morning because the spasms in his neck aren’t subsiding. He said he is having the scan to make sure there is nothing structurally wrong.

Baltimore manager Buck Showalter said the slugger was given a pain injection and trigger-point treatment on Sunday. The 41-year-old Thome, who has hit 611 career homers, hasn’t played since Friday night.

Zambrano moved to bullpen

The Miami Marlins moved Carlos Zambrano to the bullpen on Monday.

Marlins manager Ozzie Guillen said left-hander Wade LeBlanc, who has worked only in relief this season, will take Zambrano’s spot in the rotation on Wednesday night against the Atlanta Braves.

LeBlanc is 1-1 with a 1.15 ERA. He was 17-21 with a 4.47 ERA in 52 career starts the past four years with San Diego.

Zambrano is 5-9 with a 4.54 ERA. He gave up five runs, four earned, in five-plus innings of a loss to the Padres on Friday night. He has a 6.91 ERA in his last three starts.

Brewers fire bullpen coach

The Milwaukee Brewers have fired bullpen coach Stan Kyles following another meltdown by its relievers.

Brewers general manager Doug Melvin said Monday that the change was necessary to improve a bullpen that has recorded the most losses and blown saves in the major leagues.

Kyles had been the bullpen coach since 2009. He will be replaced in the interim by Lee Tunnel, who is in his fourth season with the Brewers as minor league pitching coordinator.

Padres place Thatcher on DL

The San Diego Padres have put left-handed reliever Joe Thatcher on the 15-day disabled list because of tendinitis in his right knee.

Thatcher is 0-4 with a 3.42 earned run average in 40 appearances.

Brewers’ relievers have gone 15-26 with a 4.80 ERA this season.
