Josh Fields secures fourth save Tuesday

Astros pitcher Josh Fields earned his fourth save Tuesday, striking out one in a 1-2-3 ninth inning to finish off his team's 2-1 win over the Mariners.

Seattle was only able to get two baserunners in eight innings against starter Collin McHugh, and they didn't fare any better when Fields entered the game. He's allowed just one hit and no walks in 6 1/3 scoreless innings over his last six appearances. Fields owns a 4.45 ERA and 70:17 K:BB ratio in 54 2/3 innings.
