Walker struck out two in a perfect inning to earn the save in Friday's 3-1 win over the Marlins.
Walker has allowed just one unearned run on seven hits and two walks over his last 14.2 innings, striking out 27 in that span. He's picked up all five of his saves this year over his last eight appearances, and it doesn't look like Walker will be letting go of the closer role any time soon. He's now at a 1.92 ERA, 0.87 WHIP and 92:15 K:BB through 70.1 innings this season. Walker's 67 appearances have him tied for second in the majors with Houston's Bryan Abreu and trailing only his Giants teammate Tyler Rogers (68), who earned the win Friday.
