ST. PETERSBURG, Fla. -- The Tampa Bay Rays have agreed to terms with right-handed pitchers Dylan Covey and John Curtiss on minor league contracts with invitations to major league spring training. In addition, the Rays have agreed to terms on a minor league contract, without a non-roster invite, with outfielder Johnny Davis.

Covey (COE-vee), 28, split last season between the Chicago White Sox and Triple-A Charlotte for a third consecutive year. He was with the White Sox for four stints, including his second career Opening Day roster and two trips to the injured list, both for right shoulder inflammation. His win on May 31 against the Cleveland Indians was his first as a starter since July 21, 2018 at the Seattle Mariners, snapping a streak of 14 consecutive winless starts (0-10). Over three seasons in the majors, he is 6-29 with a 6.24 ERA (250.1-IP, 182-ER) in 63 appearances (45 starts) and his ground ball rate of 50.5 pct. ranks 10th in the American League over that stretch. He was selected by the Athletics in the fourth round of the 2013 June Draft out of the University of San Diego and by the White Sox in the major league phase of the 2016 Rule 5 Draft.

Curtiss, 26, spent most of last season at the Triple-A level between the Los Angeles Angels and Philadelphia Phillies organizations. He pitched out of the Angels bullpen on April 15 at the Texas Rangers, his only outing in the majors last season. He was designated for assignment on June 3, signed by the Phillies on June 13 and released by them on July 7. He spent parts of the 2017-18 seasons in the majors for the Minnesota Twins and is 0-1 with a 6.75 ERA (17.1-IP, 13-ER) in 18 appearances, all in relief, over parts of three major league seasons. He was selected by the Twins in the sixth round of the 2014 June Draft out of the University of Texas, where he was the closer for the Longhorns team that reached the College World Series.

Davis, 29, appeared in eight games for the Rays last season, his first career major league action, after signing as a free agent on August 26. He led the Mexican League with 54 stolen bases while batting .300/.353/.392 (127-for-424) in 106 games between Dos Laredos and Oaxaca. He was selected to the Rays active roster on September 11 and was used six times as a pinch-runner and twice as a defensive replacement. On September 13 at the Angels, he tripled to lead off the 9th inning, becoming the first player in franchise history to triple in his first career plate appearance, according to Stats LLC. He was selected by the Milwaukee Brewers in the 22nd round of the 2013 June Draft and is a career .265/.326/.320 (405-for-1,528) hitter with six home runs, 76 RBI and 142 stolen bases over parts of seven minor league seasons.

The Rays have also invited 15 of their minor league players to major league spring training: right-handed pitcher Paul Campbell, outfielder Dylan Cozens, left-handed pitcher Josh Fleming, infielder Tristan Gray, first baseman/outfielder Dalton Kelly, infielder/outfielder Miles Mastrobuoni, left-handed pitcher Shane McClanahan, right-handed pitcher Sam McWilliams, right-handed pitcher Joe Ryan, right-handed pitcher Phoenix Sanders, left-handed pitcher Ryan Sherriff, catcher/outfielder Brett Sullivan, right-handed pitcher Ryan Thompson, infielder Taylor Walls and right-handed pitcher Tyler Zombro.
