Left fielder Austin Hays was placed on the 10-day injured list Friday afternoon in a series of roster moves by the Phillies.
Hays has a left hamstring strain that Phillies manager Rob Thomson said is similar to the one suffered by Brandon Marsh in early June. Marsh was placed on the IL on June 3 and activated June 12.
Without Hays, Weston Wilson and Johan Rojas will gain playing time. Wilson is the offensive half of that equation and had a solid night Thursday starting against lefty Jordan Montgomery, singling and doubling and also barely missing a three-run double that might have been fair after all.

Left-hander Kolby Allard was optioned to Triple A with Taijuan Walker due back early next week. Allard pitched well in two starts and one bulk relief appearance, allowing five runs in 13 innings.
Up from Triple A are left-handed outfielder Cal Stevenson and right-handed pitcher Max Lazar. Both had their contracts selected and were added to the 40-man roster.
Stevenson is a natural center fielder and strong defender who's spent most of the last two seasons with Triple A Lehigh Valley, performing well offensively. He's hit .307/.420/.488 this season with one fewer walk than strikeout. He has 29 games of big-league time with the A's and Giants in 2022 and 2023.
Lazar had a 2.40 ERA with 35 strikeouts in 30 innings with Lehigh Valley after opening the season with 10⅓ scoreless innings at Double A. He was the Phillies Minor League Pitcher of the Month in June with a 0.00 ERA and 0.49 WHIP in 11 appearances.

To make room on the 40-man roster for Stevenson and Lazar, Darick Hall and right-hander Max Castillo were designated for assignment.
