Brad Keller: Everything you need to know

Keller picked up the save Wednesday against the Athletics, allowing no runs on one hit and two walks in the ninth inning. He struck out one. Closer Jhoan Duran was shaky in his return from the injured list Tuesday, allowing one run in the ninth frame versus the A's, and he was presumably unavailable to work back-to-back days. Keller let the possible tying run get aboard, but he was able to strand the bases loaded for a scoreless outing. The right-hander has converted all three of his save chances while posting a 4.02 ERA, 1.21 WHIP and 16:6 K:BB over 15.2 innings, but he'll likely revert back to a setup role once Duran is fully back up to speed.

Keller earned the save Monday against the Marlins, allowing two hits in a scoreless ninth inning. Keller got the job done in the ninth despite some traffic, allowing a pair of singles but limiting the damage to secure the save. After giving up a leadoff hit to Kyle Stowers, the right-hander quickly induced a double play that helped him regain control of the inning. The save was his second in a row with Jhoan Duran still sidelined. Entering Monday Keller struggled recently, allowing runs in three of his last four appearances. The 30-year-old now holds a 4.30 ERA, 1.09 WHIP and a 15:4 K:BB across 14.2 innings.

Keller recorded the save in Friday's 6-5 win over the Marlins, allowing one run on one hit and one walk with two strikeouts in the ninth inning. Closer Jhoan Duran (oblique) has been sidelined since April 11, and Friday was Keller's first save chance in Duran's absence. Keller has been shaky this season and has now allowed a run in three of his last four appearances. However, he's yet to blow a save opportunity and owns a 1-0 record with four holds and a 4.61 ERA with 15 strikeouts to four walks across 13.2 innings.
