The Mariners Friday acquired LHP Marco Gonzales from the St. Louis Cardinals in exchange for minor league OF Tyler O’Neill, who was widely considered the top prospect and best position player in Seattle’s minor league system. Except for making a spot start against Milwaukee June 13, Gonzales has toiled in the minors this season as he works his way back from Tommy John surgery.
“Marco is a quality athlete with high character and a strong pitching pedigree who we feel fits our roster well in both the near and long term,” club GM Jerry Dipoto said in a statement. “We find his current performance, preparedness and proximity to the major leagues to be very appealing traits in a pitcher, particularly a young lefty who is now under club control through the 2023 season.”
Gonzales, 25, has appeared in 12 games over parts of three MLB seasons (2014, 2015, 2017) with the Cardinals, compiling a 4-2 mark with a 5.53 ERA, including seven starts. In addition, he appeared in six innings over three games in the 2014 post-season against the Dodgers and Giants, going 2-1 with 3.58 ERA.
Thank you, St. Louis. Greatly honored to have been a part of such a great organization. Looking forward to a new chapter! Go M’s!

A plus for the Mariners is contract control. Gonzales won’t be arbitration-eligible until 2020 and won’t reach free agency until 2023. His elbow-ligament replacement surgery cost him all of 2016 and did not return to game action until May at Class AAA Memphis.
In 11 starts at Memphis, he went 6-4 with a 2.90 ERA. Since June 18, he is 5-1 with a 2.61 ERA.
The 6-foot, 199-pound lefty has twice been listed by Baseball America as having the best change-up in the Cardinals organization (2013 and 2014). In 2014, he was named the Cardinals minor league pitcher of the year.
Gonzales missed part of the 2015 season after suffering a severe left pectoral injury.
Gonzales, who resides in Seattle in the off-season, was selected by St. Louis in the first round (19th overall) of the 2013 draft out of Gonzaga University. He won the John Olerud Award as the nation’s top collegiate two-way player in 2013 after being a finalist for the award in 2012.
O’Neill, 22, hit .244 with 54 runs, 21 doubles, two triples, 19 home runs and 56 RBIs in 93 games with Tacoma this season. He struck out 108 times while drawing 44 walks and posted a .328 on-base percentage and a .479 slugging percentage.
He recently adjusted his swing choices and had good results: 13 home runs in his past 24 games and a .326/.413/.779 slash line.
The native of Burnaby, B.C., appeared in three games for Team Canada in this year’s World Baseball Classic. He went 1-for-11 (.091) with 1 walk and 5 strikeouts.
The Mariners selected O’Neill in the third round of the 2013 draft out of high school. In parts of five minor league seasons in the organization, O’Neill, son of Mr. Canada powerlifting champion Terry O’Neill, hit .269 with 89 home runs and 300 RBIs.
The move by Dipoto to improve the pitching staff was his second in two days. Thursday he acquired RHP David Phelps from the Miami Marlins for three Class A-level prospects. Dipoto paid a heavy price to land Gonzales, who will begin his Mariners career in AAA Tacoma as he works his way back from elbow surgery.
