One change to the 28 players to face the Houston Astros

It’s Monday afternoon and the Oakland A’s are about to begin their ALDS against the Houston Astros. This morning, they announced the roster they’ll use for the series.

There is only one change from the Wild Card Series roster, and it’s to add an extra pitcher. Reliever Jordan Weems was added, and to make room for him, infielder Vimael Machin was removed.

This is a sensible move. The rookie Machin didn’t make it into a single game against the Chicago White Sox, and it’s difficult to envision a scenario in which he would. The A’s already have four starting infielders (Olson, La Stella, Semien, Lamb), plus backups in Tony Kemp and Chad Pinder, plus another emergency backup for shortstop in Nate Orf. Even among that group, Orf only saw one defensive inning last week and Kemp didn’t play at all, so it would require several things happening all at once for Machin to even begin to become an option. His bench spot was being wasted.

Meanwhile, you can always use more pitching. Maybe a game goes to extras. Maybe a starter gets knocked out early, like Mike Fiers in the 2nd inning of Game 3 against the Sox. Maybe there’s an intentional piggyback/bullpen strategy. Whatever the case, there’s one more arm available, and it’s a good one as Weems had an impressive rookie year in Oakland’s deep and excellent bullpen.

Weems, 2020: 3.21 ERA, 14 ip, 18 Ks, 7 BB, 1 HR, 3.05 FIP, .295 xwOBA

All of those numbers are better than average, except the walk rate which is a bit high.

As for the Astros, their roster looks as healthy as it has all year. There are still big names missing, of course, like Justin Verlander and Yordan Alvarez. But the star infield is back intact, and the main outfielders are there, and some relievers have returned — though there are still six rookies on the pitching staff.

Like the A’s, their only change from their Wild Card Series is adding an extra reliever, Luis Garcia. He made a spot start against the A’s this year and tossed five scoreless frames with just one hit allowed. Infielder Jack Mayfield was removed to clear space.

Another new name is Chas McCormick, who has not yet debuted in the majors but was on the Wild Card Series roster (and didn’t play). Based on his gaudy minor league steal numbers, he’s presumably here to pinch-run.
