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.
By the numbers: Jump's last four starts: 1.42 ERA, 4 ER, 25.1 IP. MLB career to date: 118 batters faced, 0 home runs allowed. Recent outing reported June 19: 7 scoreless innings, 7 strikeouts, season ERA down to 2.37 through five starts.
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.
