What happened: Philadelphia has filled rotation turns with Brian Keller bullpen games. Clay Holmes is working back from injury after shifting from relief work to mostly starting with the New York Mets.
Why it matters: His sinker-heavy approach depends on infield outs, creating a fit question for the Phillies' defense. His high-leverage history with the New York Yankees could give Philadelphia another October role if it reaches the postseason.
By the numbers: Holmes has a 3.26 ERA over 218 1/3 innings with the Mets, mostly as a starter. As a Yankees reliever, he threw about 2 mph harder; his current mix adds a kick-change against left-handers and leans more on curves and cutters against right-handers.
What to watch: Holmes' next rehab step and Philadelphia's rotation moves are the key markers before the Aug. 3 deadline.
