NEW YORK - While the Seattle Mariners were losing to the New York Yankees in New York on Wednesday night, veteran right-hander Casey Lawrence was spinning a historic gem for the Triple-A Tacoma Rainiers.

Per Kristilyn Hetherington of the Mariners PR team:

Per Tacoma's PR: Lawrence became the 1st minor league pitcher at least 37 years old to throw 7.0 shutout without a walk since Brad Penny (7.0 IP, 7H, 0R, 0BB, 5K) did so for Charlotte against Gwinnett on August 11, 2015.

Lawrence, 37, has been up-and-down with the Mariners all season, and he even made an appearance for the Toronto Blue Jays as well. He's been designated for assignment multiple times by Seattle, but keeps finding his way back to the organization and on the roster. He's gone 1-2 with a 4.08 ERA this season and he threw five solid innings against the Chicago White Sox in a 1-0 loss during his last major league appearance in late May.

Thus far, he's struck out seven batters in 17.2 total innings.

He's 3-2 with a 4.29 ERA in Triple-A this season. He's struck out 29 batters in 42.0 innings.

At the big-league level, the Mariners are 48-44 and in second place in the American League West. They are currently tied for the third and final wild card spot in the American League wild card race.

They will finish out a series with the New York Yankees on Thursday afternoon with first pitch coming at 4:05 p.m. PT. They'll head to Detroit aftewards to finish out the first half of the season.
