What happened: Gage Jump has posted a 1.42 ERA over his last four starts, allowing four earned runs across 25.1 innings. MLB noted he has faced 118 big-league batters without allowing a home run.

Why it matters: That run gives the Athletics another rotation development to track as they try to stay in the AL West mix. For a young starter, missing barrels and keeping the ball in the park can change how quickly a team trusts him with deeper outings.

What to watch: Watch whether Jump keeps holding a rotation spot and how the Athletics manage his workload. His next start will test whether the homerless streak can survive a second look from big-league lineups.
