Both teams are 1-1 after splitting the first couple of games of the season.
De Jesus had four strikeouts and gave up just four hits and one walk over seven innings to pick up the win. Leahy gave up three hits over the final couple of innings, including two in the ninth, but survived to earn his first save of the young campaign.
Johnson City won despite striking out 10 times and accounting for only three hits the entire game. The Cardinals got on the scoreboard first when Donivan Williams hit a RBI single to score Sanel Rosendo in the second inning. Rosendo had singled, then advanced to second base on a wild pitch and to third on a ground out by Nolan Gorman.
Dariel Gomez provided the game’s only other run in the sixth inning with a solo shot over left field.
Bluefield threatened in the ninth when Alejandro Kirk singled to start the final inning, but John Aiello hit into a double play on the next at-bat. The Blue Jays’ Patrick Morris followed with a double, but Luis De Los Santos flew out to right field on the next attempt to end the game.
Overall, the Blue Jays were 0-for-3 with runners in scoring position and left seven batters on base.
Eric Pardinho (0-1) suffered the loss, despite striking out five and giving up just one run and two hits.
The teams will wrap their three-game series in Bluefield on Thursday, starting at 7:05 p.m. before the Cardinals open the home season Friday by starting a three-game series against Kingsport.
