After he posted a 5.79 ERA in 2017 and was left off Houston’s postseason roster, Pascagoula native Tony Sipp’s future with the World Series champs appeared rather cloudy. The left-hander’s results in spring training weren’t great, but an injury to another relief pitcher enabled Sipp to grab the last spot in the Astros’ bullpen. To his credit, he has not let go. The former Moss Point High and Mississippi Gulf Coast Community College standout enters the second half of the season with a 1.93 ERA in 27 appearances. Over his last 15 games, it’s a 0.66. Home runs plagued him in 2017, when he yielded eight. He hasn’t allowed one this year. Sipp, now 35 years old, is only used situationally – he’s worked just 23 1/3 innings – but he has been effective in his role. “I can use him a little bit more, the way I used him in 2015 and 2016, and he adds a different dimension to a bullpen that I’ve been able to mix and match,” Astros manager A.J. Hinch told The Houston Chronicle last week. The first-place Astros are said to be seeking bullpen help for the second half (and beyond), but Sipp’s job would appear secure. Quite a change from just a few months ago.
