The Giants added a body to their infield depth chart this week, claiming Shay Whitcomb off waivers after the Astros designated him for assignment. It's the kind of roster move that barely registers outside the standings page, but it says something about where San Francisco is at down the stretch — always scanning for cheap depth, especially guys who can bounce around the dirt and the outfield corners.
Whitcomb never really got a foothold in Houston. Across parts of 3 seasons with the Astros, he hit just.167/.216/.292 in 102 career plate appearances, and this year he managed only 3 hits in 23 at-bats before getting squeezed off the 40-man. The DFA came so Houston could open a spot for Nelson Velazquez, the outfielder they picked up from the Cardinals — a straightforward numbers game that left Whitcomb searching for a new home.
That lack of big-league production doesn't tell the whole story, though. In Triple-A over 2024 and 2025, Whitcomb was legitimately productive — a 128 wRC+ with 50 home runs and 42 stolen bases across roughly 950 plate appearances, plus a walk rate north of 11%. This year's Triple-A line,.274/.338/.420 with 23 steals, came with some BABIP inflation, but the track record of a guy who can hit for pop and run is exactly the type of upside a team stashes in the minors and monitors.
San Francisco didn't just add him and move on — they made a corresponding move too, transferring right-hander Trevor McDonald to the 60-day injured list to clear the 40-man spot. McDonald needed Tommy John surgery earlier this summer and is done for the year, so the Giants used his absence to take a flier on Whitcomb rather than let a rebuilding-adjacent contender like Houston simply cut him loose to the wind.
Whitcomb has been assigned to Triple-A Sacramento for now, not the big-league roster, and he still has an option remaining, which gives San Francisco real flexibility with how they use him. It's a low-cost, low-risk grab — the kind of move that either quietly pays off in September when someone gets hurt, or fades into the background as organizational depth. Either way, it's one more body the Giants control heading into the final stretch.
