SEATTLE -- The Mariners announced the signings of four additional 2015 Draft picks Monday, bringing the club's total to 33 of 40 players signed.
Seattle signed ninth-round pick Conner Hale, a third baseman from LSU; 23rd-round pick Art Warren, a right-handed, 6-foot-4 pitcher from Ashland University in Ashland, Ohio; 31st-round pick Logan James, a left-handed pitcher out of Stanford; and 36th-round pick Matt Walker, a right-handed pitcher from Weatherford College in Weatherford, Texas.
Hale, 22, hit .327 with four home runs and 56 RBIs during his senior season for a Tigers team that swept its regional and a super regional against Louisiana-Lafayette on its way to the College World Series. LSU's run ended at the hands of TCU in Omaha on Thursday.
Warren, from Napoleon, Ohio, started 12 games for Division II Ashland in 2015, finishing his junior season with a 5-4 record and a 3.88 ERA.
James worked mostly as a reliever for the Cardinal, earning a 2-4 record and posting a 4.75 ERA in 17 appearances in 2015, 15 of them coming out of the bullpen. Walker, 20, made 12 starts for Weatherford, finishing his 2015 season with a 7-1 record and a 4.59 ERA. He struck out 78 hitters in 66 2/3 innings.
Hale and James have been assigned to the Class A Everett AquaSox, while Warren and Walker will start their rookie-ball careers with the Arizona League Mariners in Peoria, Ariz. With Hale's signing, the Mariners have reached deals with each of their top 15 Draft picks.
The Mariners' highest unsigned Draft pick is 16th-round selection Ricky Eusebio, an outfielder for the University of Miami who also just wrapped up a trip to Omaha when his Hurricanes lost to the Florida Gators on Wednesday.
Seattle also has not signed local talent and 20th-round pick Parker McFadden, a right-handed pitcher out of Yelm High School in Yelm, Wash. McFadden is expected to stick with his commitment to play for Washington State.
• Mariners manager Lloyd McClendon said on Monday that lefty James Paxton had not resumed throwing since straining a tendon in the middle finger of his throwing hand.
Paxton has been on the disabled list since May 29 after he was pulled from a May 28 start against the Indians when he felt discomfort in his left middle finger. Paxton is 3-3 with a 3.70 ERA in 10 starts for Seattle this season.
