Phillies’ moves include placing OF on 10-day injured list..

The Phillies announced a series of roster moves on Friday. Outfielder Austin Hays has been placed on the 10-day injured list, retroactive to Aug. 8, with a left hamstring strain.

Left-hander Kolby Allard was optioned to Triple-A Lehigh Valley. To take those two roster spots, the club selected outfielder Cal Stevenson and right-hander Max Lazar.

To open 40-man spots for those two, first baseman Darick Hall and righty Max Castillo have been designated for assignment.

Hays left Wednesday’s game with left hamstring tightness, per Todd Zolecki of MLB.com on X. It’s unclear how long he is expected to be out of action, but it seems the Phils will have to progress for at least a week without their recent outfield upgrade.

Acquired from the Orioles prior to the deadline, Hays hit .263/.282/.395 and stole two bases in his first 10 games with Philadelphia, but will now sit on the shelf for a while.

The club still has Nick Castellanos, Brandon Marsh, Johan Rojas and Weston Wilson in the outfield mix, but will bolster that group with Stevenson.

Now 27, he was claimed off waivers from the Giants in May of last year but then was outrighted off the Phillies’ roster the following month.

He’s spent all of this year putting up great numbers at the Triple-A level.

In 91 games for the IronPigs, he’s hit seven home runs and drawn walks at a massive 16.4 percent clip while limiting his strikeouts to a 16.7 percent strikeout rate. His .307/.420/.488 batting line translates to a 138 wRC+ and he’s also stolen 27 bases while lining up at all three outfield spots.

Stevenson has put up strong numbers in the minors before but struggled in limited major league looks. He has 29 big league games under his belt at this point, with the Giants and Athletics, but he hit just .145/.259/.188 in those contests.

If things click this time around, he still has one option remaining and he won’t be able to get to one year of service time this season, meaning he could be retained well into the future at minimal cost.

But getting Stevenson onto the roster seems to have cost Hall his spot. He has done some exciting stuff at the plate in the past but is not having his best year.

He’s spent the entire season in Triple-A and does have 12 home runs, but his .248/.324/.402 line translates to an 86 wRC+ in the strong offensive environment of the International League this year.

Hall is in his final option year and therefore will be out of options in 2025. Even before this year’s struggles, he didn’t have a path to playing time in Philadelphia with Bryce Harper at first base and Kyle Schwarber in the designated hitter slot.

With less roster flexibility next year, he was going to have a hard time hanging onto his roster spot going forward, so the Phils have nudged him off today.

With the trade deadline now passed, they will have no choice but to put him on waivers in the coming days. Clubs may be interested based on his past performance.

From 2021 to 2023, he hit 60 home runs in 297 minor league games, walked at an 11.1 percent clip and had a 21.1 percent strikeout rate.

His combined .261/.351/.486 batting line translated to a 117 wRC+. He can be kept on optional assignment for the rest of this year but will be out of options next year and has no defensive versatility as a first base/DH-only player.

The club also made a switch on the pitching side, giving Lazar his first major league call. Drafted by the Brewers back in 2017, he climbed as high as Double-A but didn’t get the major league call by the end of 2023 and qualified for minor league free agency.

The Phillies signed him to a minor league deal in the offseason and have been watching him post great results. In 40 1/3 innings between Double-A and Triple-A, he has a 1.79 earned run average, 33.8 percent strikeout rate and 5.8 percent walk rate.

Those impressive numbers get him up to the Philly bullpen and he’ll be making his major league debut as soon as he gets into a game.

Castillo, 25, was claimed off waivers from the Red Sox in February. Like Hall, he is in his final option year and may been running out of time.

Claimed off waivers from the Red Sox in February, he has been providing the Phils with some starting depth but the results haven’t been there this year.

In 52 innings between Double-A and Triple-A, he has a 7.62 ERA, 16.4 percent strikeout rate and 10.4 percent walk rate.

The Phils will have to put him on waivers in a few days. As recently as last year, he seemed like a capable up-and-down arm, as he posted a 4.43 ERA in the majors with the Royals and a 4.58 ERA at the Triple-A level, but it’s obviously been a different story this year.

Between Castillo and Hall, neither has a previous career outright nor three years of big league service time. If either of them clear waivers, they would stick with the Phils as non-roster depth.
