McGrath has been with the Padres since 2014, when they selected him in the 36th round of the draft, and made his major league debut last year. Across 23 innings in San Diego, including four this season, the 25-year-old has notched a 3.13 ERA with 7.83 K/9, 3.52 BB/9 and a minuscule 28.1 percent groundball rate. Additionally, McGrath has limited left-handed hitters to an ugly .152/.243/.250 line.
Should a team in need of a lefty reliever claim McGrath, it would have the ability to send him to the minors. McGrath still has three options remaining, and has spent most of this year with the Padres’ Triple-A affiliate.
