For Twins reliever Taylor Rogers, MLB’s updated guidelines in cracking down on the use of foreign substances on baseballs is going to take some adjusting to.

The league's new enforcements will include periodical checks from umpires on starting and relief pitchers either between innings or after pitching changes have been made.

MLB stated in its memo that “enhanced enforcement of Official Baseball Rules 3.01 and 6.02(c) and (d), which prohibit applying foreign substances to baseballs, will go into effect” beginning on Monday. Of the substances banned in rule 3.01: soil, rosin, paraffin, licorice and sandpaper are among those listed. Part of MLB’s memo on Tuesday also stated that “players may not intentionally combine rosin with other substances," citing sunscreen as an example.

“There's no one way to go about this,” said Rogers, the Twins’ MLBPA player representative. “Obviously, the sunscreen [and] rosin is not acceptable. What are we doing for day games? That was one of the things that wasn't mentioned in the memo. We talked about night games. Places with roofs. But if you're wearing sunscreen in a day game in Kansas City when it's 105 [degrees], I'm not really sure how that's going to play, and I think that's why maybe it's not being enforced till Monday. Maybe it'll give us some time to work out the kinks.”

Rogers added that the implementation of the rules could be uncomfortable and strange at first. He said they could come in situations when a player is roughed up or gives up the lead following a bullpen appearance, and then is inspected shortly after by an umpire.

“Say I go in and give up the lead, you're not going to be in the best mood of all time,” Rogers said. “And having somebody check your stuff is not ideal, but that's what we have to work with.”

Twins manager Rocco Baldelli said certain situations could take some adapting to, but the implementation of the rules is what’s necessary for the game of baseball.

“I’m glad I’m not making these rules, because these are very, very difficult things to deal with,” Baldelli said. “I feel for the umpires, too. It’s not going to be easy on them either, but in order to get where we need to go, we’re probably going to have to have some uncomfortable conversations and interactions. So what Rog is saying is right.”
