TAMPA, Fla. — New York Yankees star slugger Aaron Judge will soon get an offer for a long-term contract extension, General Manager Brian Cashman said Saturday.

“Between now and Opening Day we’ll make an offer and he’ll obviously receive an offer and all the conversions will have taken place and will either resolve into a multiyear deal or it won’t,” Cashman said.

“We’re committed. We’ll make an offer and hear what he has to say in response and then it will be pencils down before opening day,” he said.

The Yankees open on April 7 at home against the Boston Red Sox.

Judge has said he doesn’t want to negotiate an extension during the regular season. The outfielder, who turns 30 next month, is eligible to become a free agent after the World Series.

The Yankees and Judge so far have failed to reach a deal for 2022, which could result in the two sides heading into arbitration during the season. He asked for a raise from $10,175,000 to $21 million, and the Yankees offered $17 million.

STICKY SUBSTANCES: Major League Baseball is asking umpires to make more random checks of pitchers for sticky substances after watching its crackdown become less effective late last season.

MLB instituted regular checks last June 21 for grip aids. Seattle’s Héctor Santiago was ejected on June 27 and Arizona’s Caleb Smith was tossed on Aug. 18, and both received 10-game suspensions.

“After an initial dip in spin rates as a result of the periodic checks, unfortunately the data showed that spin rates started to rise toward the end of the season as players grew accustomed to the circumstances of routine umpire checks,” MLB Senior Vice President of On-Field Operations Mike Hill wrote in a memorandum Friday to team owners, executives and managers, and all major and minor league players.

“As a result, umpires have been instructed to be more vigilant and unpredictable in the timing and scope of their checks during the 2022 season,” he said.

The memorandum, first reported by Sports Illustrated, was obtained by The Associated Press.

GUARDIANS: Reliever James Karinchak could miss the start of the regular season with a shoulder strain suffered earlier this week in camp.

One of Cleveland’s top bullpen arms, Karinchak underwent an MRI on Thursday that revealed a mild strain in his right teres major muscle. The team said Karinchak has already shown improvement, but won’t throw for up to 10 days before being re-evaluated.

The Guardians open the season on April 7 in Kansas City.

The hard-throwing Karinchak, who also has a devastating curveball, went 7-4 with a 4.07 ERA and 11 saves last season. Manager Terry Francona has used Karinchak in a set-up role and as a closer.

BLUE JAYS: Pitching coach Pete Walker apologized Saturday after being arrested on a charge of driving under the influence a day earlier.

Walker was arrested early Friday morning in Pinellas County, Florida, and released later that day on $500 cash bond.
